[Q] Which microSD card will maximize performance on the Xperia Z1 - Xperia Z1 Q&A, Help & Troubleshooting

Hi, I am debating on which microSD card I should purchase for the Xperia Z1. These are the two products I am looking at currently:
Sandisk Extreme PLUS microSDXC UHS-I (SDSDQX-064G) (Red/Gold)
Capacity: 64GB
Read Speed: Up to 80MB/s
Write Speed: Up to 50MB/s
$70.54CAD (Regular: $199.99CAD)
SanDisk Ultra microSDXC UHS-I (SDSDQX-064G) (Red/Grey)
Capacity: 64GB
Read Speed: N/A
Write Speed: N/A
Transfer Speed: Up to 30MB/s
$59.99CAD (Regular: $69.99CAD)
I would prefer the higher performance card but I am not sure if the Xperia Z1 can benefit with that extra speed.
I am planning to use the microSD card for storing 1080p movies, flac and apps.
Any suggestions would be much appreciated.
Thank you very much

With the Sandisk I had bad experience, I use Samsung Ultra-Pro 64GB SDXC, Write Speed 20mb/s Read Speed 70mb/s and I got no problem at all, is damn fast. And chipper than Sandisk. I will recommended also A-Data, very good, but hard to find. Anyway in any case you will not see the difference.

Thanks for the quick reply, eclyptos
What kind of bad experience are you referring to?
See, in terms of write speed and read speed, I have heard that smartphones cannot benefit from anything above 30MB/s, I have not been able to find solid proof however. I will be playing a lot of large mkv videos, so I am hoping there wwill not be any stutter.

Losing data or corrupted, and after few weeks the sd stopped working and I had to replace the sd. The second one was working good but the access to the card was laggy, so I sell the SD. Was a year ago and maybe, I said Maybe, the newest sandisk are better but I got 3 Samsung and they working like a sharm.

All new smartphones are implemented to working with SDXC so faster the SD will be, it will just guarantee the best work. There is not any proof but the hardware are made to support all the new technology so probably they have higher bandwidth.

Ultra speeds are not that great, my class 8GB class 4 is almost as fast as the ultra in this phone. My old 16GB class 10 is faster than the ultra (was more expensive also when it was purcahsed) You get what you pay for I think.
I have a 8GB Sandisk card class 4, 16GB class 10 Sandisk card, then the 32GB ultra card (now sold) 64GB Extreme due to arrive.
I have a sandisk extreme that should arrive today or tomorrow, will post to advise.
The reason I purchased the extreme was that another user posted 40MB/s write using this card in the Sony Z1, I will confirm later.

SDXC is not the issue, it is more that we need android to support UHS Speed Class 1 until then we will be constrained to get the full performance out of the memory cards

Who said the SDXC is the issue here, the cards was faulty. Also I was saying about hardware, software is good enough. You can buy best card ever and will be no difference on smartphone to see with your eyes. I did a bandwidth test with SCSI app and what I paid I get. Do you think we need write speed 40mb/s for smartphones, Where?
We need read speed, so any app or vid will not be stutter or laggy. You spending money for a card with highest writing speed just for nothing. This is my advice.

You said SDXC is faster, when it is not, read what I was quoting from you I was just highlighting the performance issues is if the hardware can support the new UHS-1 format to get full speed.
potentially 4k video, raw camera recording, and uploading large files to the phone, just a few from the top of my head.

Format SDXC in FAT32 and test the speeds, the SDXC is faster because of his exFAT system is more efficient. All new devices support now exFAT which is faster than FAT32. I had SDXC 64GB on my old device which was not supporting SDXC and with FAT32 was, sorry, is working fine, but slower. I did my tests.

Look, I said this in another thread, the 4K is useless so high writing speed either. When we will see on the market 128Gb of microSD we will talk about this seriously. Now is just a wast of time. Z1 was never meant to record 4K even if it can with some tricks but he still support UHS-1 format.

Don't touch the ultra if you are after performance and future proof yourself.
see attached, brand new 64GB Sandisk Extreme.
You can clearly see here the bottle neck with the phone, almost everything at least twice as fast with my USB3 UDMA card reader vs the phone interface from the computer
Sandisk Ultra in phone best 40MB/s average around 30MB/s read but around 10-12MB/s write.

I'm using the Samsung Pro 64gb SDXC UHS-1 as well. This card is very fast and good price as well. I bought it on Ebay for about 65 AUD. I've tested on the GS4 & my XZ1 as well the speed is awesome... But you should be aware of fake cards goin' on at Ebay. It is very important where the card is coming from. The other day I bought another card for my brother in law, on the package it said made in Korea, but on the card itself made in Taiwan was printed on and guess what... The speed ain't the same!!!
Before you buy the card, ask the seller specifically if; "made in Korea" is printed on the card itself.
I tested with a few sd tester here are the results:
Made in Korea W 18mb/ R 42mb
Made in Taiwan W 9mb/ R 16mb
I've uploaded 2 pictures the one on top is FAKE from Taiwan!!! So now I've to return it to the seller and ask for a refund...

I see, to get that scores with Extreme Sandisk and reach 90mb/s you have to have USB 3.0 on your computer and any device to test the card have to be implemented with USB 3.0 if not all your test will stack al 35mb/s in reading and writing.
Anyway that Sandisk Extreme is very impressive but I told you, the Android and the hardware on Z1 support that kind of card but they are not made to reach that speed. What for? You will still not have problems what so ever.
PS: which kind of Benchmark App did you use to test the card, I want try with mine and post some results.

I'm using Sandisk Ultra 64GB, no issues and works nice, I use it to store some music, video and save my pictures / recordings.

So we are stack on 42mb/s for external memory bandwidth. That's ok. If you see we have 70mb/s in internal memory. Wath we can do? Nothing, we have to keep Z1 like that. It was meant to be.

Same here corrupted sd card experience using sandisk...
Now Im using transcend for 6 months, very reliable, no problem at all.

I always knew that I would not get full speed out of the card due to the android interface, this has been my biggest annoyance for a long time, but three times the speed in phone to copy movies, mp3s, flac... will definately give me benefit, titanium backup now flies.
I labelled most of the files so if you look down the bottom you will see what picture is what.
Which bench mark?

Unlucky, I have been using Sandisk for a long time, never had any problems. All of mine were 100% genuine, that could also be part of the difference as there are so many knock offs out there.

Been using this one for quite some time and it's been superb, never had to reformat due to it being glitchy or corrupting anything.

Had it since the S3 and was actually used as the internal memory as i switched the memories around, it was then used in the Asus Prime and then the Galaxy Camera and finally it's now in my Z1 and i'm using folder mount (which is excellent by the way) formatted into Fat32, 4096 byte allocation size i think.
It's been like a marine for me, but i have heard of people having problems, just not in my case.

It was a pc based tester atto benchmark.
The method in which the OS is accessing the micro sd cards, not compliant to UHS-1 as well as the bridge between the USB interface
Yeah I was also looking at the Samsung chips, they were looking quite good, the sandisk for me was on special and ended up a very similar price

That why I was telling to do not spend money for super pro ultra extreme ultimate Sd cards, is not needed. But if the price is low probably is worth to buy.

32gb class 2 vs class 4

Hey guys,
I'm interested in getting a 32gb card. I will be watching movies off it and just basically reading books. Is there a huge diff between the two? I googled and I found the diff write and read speeds but my question is how relevant is it to the user? Like will the movies be choppier or books open slower? etc

Sadly, to throw a wrench in your question, there is authority behind the class markings. Basically, there is nothing stoping makers for marking a card Class 10, even when it can barely do 1MB/s writes. So, how does that answer your question?
It comes down to brand. Sandisk by far makes the best microSD cards, which almost always outperform their rating. I have an 8Gb Class 2, that constantly benches at 5MB/s sustained write, and 12MB/s sustained read. I also have an 8GB Kingston clas4, that can barely hold 2MB/s write, if it is lucky. The other issue few talk about is random reads, where again, the Sandisk is much faster (and random reads are not part of the class specifications)..
So, if you get a decent brand (again, Sandisk), a class 2 should be suitable for all music, and most movies. If you can afford it, class 4 will give you wiggle room.
How about adata? Have you had any experience with them?

personal experience no, but i haven't heard alot bad (actually, better than Kingston in many cases). I know they have decent prices on their cards.
With what i was saying before, it is fair to mention that while slow, my Kingston does still work. But saving things to it was painful, and so i avoid its use. Even if you don't get the fastest card, i think the biggest pain will be filling it once.. after that, using it should be ok..
I see. What about the performance? Saving stuff to it isnt much of an issue to me I think. Im more concerned on the performance. Like running movies off it and launching programs etc the sandisk sounds awesome but the price is much higher
For the use you are planning(movies) the big factor will be sequential read speeds. The class system is too easy for the manufacturers to game. Check the specs for the card you are looking at...if they don't tell you, it's likely because they suck. Sandisk class 2 cards are, as stated, usually better than the class 2 they are rated.
so you guys would recommend a class 2 32gb sandisk over a class 4 adata card of the same size yeah?
Can't really say one way or the other. From reading reviews at Newegg...seems like Adata tech support might be a bit iffy...then again those reviews are usually posted by those who have issues or feel like they have to defend their purchase(ie...fanboi's).
One thing I can see for myself...Adata is the only manufacturer on Newegg to actually list their full specs. Even on the manufacturers pages...only Adata has manned up and posted specs. otherwise they all just fall back on the SDHC specifications for class...which as stated can be gamed a bit.
At the end of it all..it's your cash...spend it the way you feel like...do some research for yourself first.
I have a scandisk class 4 32GB and it is way slower then a smaller class 6 that I have. For me, I don't think I could stomach anything slower then the class 4 for large files.

Sandisk is great. I was originally running Nookie Froyo from a class 2 Sandisk. It was actually pretty solid. I moved up to a Transcend class 6 and it's been good too. Both seem to perform well over their class specification when I'm transferring files and have been very stable.
On the other hand, my friend has a Kingston class 10 which seems pretty buggy. A lot of force close errors, looping boots, etc. Though these could just be a coincidence. Haven't seen him transfer any files though, so I can't judge the speed.
SD Cards..
You should be aware that Sandisk, Adata and others do not actually manufacture flash memory chips, they mostly package and test it - the big boys in the game are Intel, Samsung, Toshiba and Hynix. Depending on where or from whom Sandisk buys the basic chip the specs may be different.

Actually there is a requirement if you're in the SD Association. But in reality anyone can stamp a C10 on a card, especially no-name brands.

Absolutely. AData are junk in my experience.
Kingston and SanDisc are the only ones that are reliable for all devices that I've owned. Others are hit and miss, PARTICULARLY Patriot. I've had 3 Patriot cards that were JUNK in most devices. I had two Patriot SD cards for a camera that were fine but couldn't work right in anything else, and I (stupidly) purchased an 8G uSD card a few years ago for a phone and it was junk there, and I've periodically tried it in new devices for giggles and it's been junk in every single one.
I'll bet a SanDisc C4 out classes any other brand C10 in device like a phone or tablet.
Side note: All 3 Patriot's work just fine on my computer. I did tests particuarlly on the 8G uSD over and over and over and it was fast and reliable in my card reader. Every device locks up or goes slow as hell if it's in 'em. My guess is that they didn't follow specs closely.
So a Sandisk Class 4, 8GB would be a good pick?

SD cards are a complicated topic... not to throw another wrench into the system but you also want to be careful WHERE you buy your card. SanDisk counterfeiting is RAMPANT since a vendor can take a blank card, less than a pennies worth of ink and then charge you some percentage of the SanDisk price while still reaping a huge profit. As unfortunate as it is, real SanDisk cards always seem to just work while the other cheaper cards can be hit or miss. Honestly though the only real problem with off brand cards and the NC I have had is that they don't always boot so good. So I use my SanDisk 8GB C2 (bought from Costco) to boot and my Patriot 16GB C10 to watch movies and store stuff. Buying from Retail, Newegg, or Amazon (Amazon itself, not a sold through vendor on Amazon) should help make sure whatever you buy is the real thing. Good Luck!

[Q] Minimum micro SD class for the galaxy note

Hi guys, I am about to purchase my galaxy note next week and I was wondering if anyone could shed some light into the matter..
Which class of micro sd card should I buy? (minimum) I was hoping to get a 64gb but if that would underperform, there would not be much of a sense to it.
The maximum reading/writing I will be doing in the note is probably playing 1080p playback + mirroring it to the tv. maybe some hi definition video recording as well straight to the memory card.. but most often than not, I would play a 720p mkv movie.
Would a class 4 suffice? Any suggestions on which brands I should look at / stay away from?
Class 4 of any decent brand should suffice.
Class 2 cards from Sandisk will also suffice (their read/write speeds are enough for 1080p encoding and decoding). May be a hassle if you regularly transfer a lot of data to and from the card since thats the time when the slower R/W speeds will come into play.
Why get anything less than class 10? If you can afford a Note, you should be able to spare another $20 for a fast sdcard...
class 10 cards can cost upwards of $80 for an 8gig card.

i picked up my class 10 a-ram 32gb microsd for $49.95AU + shipping.
it really depends on what you plan to use your note for. if youre filming 1080p video at the default 17mbps, thats about 2mb/s that you'd want minimum for just filming. so any speed should be fine as long as its above class 2. i just prefer faster cards since theyre getting cheaper.

I've read class 10 doesn't always mean fastest read speed or something to that effect. Not always beneficial to get a class 10 since it writes faster but doesn't always means it reads faster. Someone else can probably elaborate for me.

A-RAM is the brand. i bench'd it. write speeds are 11mb/s, read speeds are 14mb/s.
it was one of the random daily specials they had at www.shoppingsquare.com.au a week or so ago.
right now, the next best deal they have is http://www.shoppingsquare.com.au/p_276323_Kingston_32GB_Class_10_Micro_SDHC_Memory_Card

normally read speeds of class 10 are still higher than write speeds. but the read speeds dont really vary much between classes. my kingston class 10 reads at 12mb/s, my a-ram class 10 reads at 14mb/s, my sandisk class 2 reads at 10mb/s. so if all you need is read speed, then any card will do.
even class 2 or 4 on Sandisk it will work fine. i believe just buy a good make one ( not a fake from China ) , but i bought mine Lexar class 10 and work great , i couldnt be happier.

I've read class 10 doesn't always mean fastest read speed or something to that effect. Not always beneficial to get a class 10 since it writes faster but doesn't always means it reads faster. Someone else can probably elaborate for me.

It doesn't necessarily write faster either!
All the class indicates is the minimum sustained write speed under optimal (i.e. unfragmented) conditions. It says nothing about the read speed, which is what is generally important in mobile devices since they are usually used for content consumption rather than creation.
As NZtechfreak has already mentioned, Sandisk Class 2 cards almost always well exceed the class minimums - I've been using 16gb Sandisk Class 2 cards in my phones for a long time now, and I've yet to get one that had a write speed less than the Class 6 minimum of 6MB/s, and the read speed has always been 20MB/s or above.

A good read why Class 4 cards are the best ones to use for your smartphone: http://forum.xda-developers.com/showpost.php?p=14456360&postcount=42
I started out with a Kingston Class 2 32GB I had laying around, and then switched to a Class 10 32GB made by PNY that I got from Microcenter for $59.95.
There was a very noticeable difference in photo taking lag and the media scanner, plus app access on the card. Now there is almost no photo lag, from snap to saving. Haven't messed with the video much yet...
I've Samsung class 10 32 gb. It's really good, but my device started rebooting because of it. "System Process has stopped working."
What I found out is that after removing my micro sd my device is a hell FASTER than before!!!
Maybe a faulty micro sd, no since it works fine in my pc and other devices.
I want to check does any of you have the same problem???

[Q] Optimum MicroSD Card for Galaxy Note

Guys,
For use with Galaxy NOTE (GT-N7000) Which Memory Card Should I get ?
Hoping to order one over ebay next week.
* 16GB or 32GB ? (Larger the better, but I need to know whether the note will handle 32GB)
* Which Class ? (4, 6 or 10 ?)
Thanks !
yes it will handle 32gb, it will also handle 64gb cards
it is your choice on what size you get it is your requirementrs that decide this
i havea 32gb class 4 card and it suits my needs, class 10 are wasted in mobile phones
I also heard Note can handle 64GB MicroSD, though it's very expensive atm.
Sandisk Class 4 32GB would be an optimal choice for its price, quality and speed.
Samsung 32GB Class 10 for around $50CDN shipped on eBay. Performance is quite good.

It's newly released so not many people have their hands on. Got a lot of features which is kind of appealing to me lol :d.
Just that I read somewhere Class 4 provide much better handle than Class 10 at reading random data, while Class 10 excels at writing large files. So if you want to transfer lots of space then Class 10 would be better.
One more thing, the Class X only tells the minimum speed, while the maximum speed depends on the card make, brand, technology...
After searching online, I assume Sandisk is the best.
Over here class 4 and class 10 cards are almost the same price so I just went with a 16GB class 10 myself. Working just fine, though I didn't expect it not to anyways.

Indeed. My class 10 can write at 16 megabytes/second (not megabits!) and read at 20 megabytes/second, it's just that the specification is several years old and they defined speeds only up to class 10.

+1 I have one in my note and it is fine
Class 4:
High sequential read speed/medium sequential write speed
Good random 4k_Thread read/write speed (needed to initialize some system relevant data faster that's why SSD on PC can boot so much faster than HDD)
Class 10:
High sequential read/write speed (if you copy media files very often that's the one for you)
Good random 4k_Thread read speed/very very VERY horrible random write speed
Both don't have Problems recording HD material on note and also playing them.
Remember : higher class doesn't necessarily mean it's better.
Thanks a lot for the input guys !!
Samsung 32GB Class 10 it is then..
How about Sandisk Mobile Ultra 32Gb Class 6 and I think the performance is above the Samsung Class 10?

I've heard lots of good things about Sandisk lately..
I only have files I rarely use on the 'external' card. These are usually large files like mp3 or videos. As such I went for the Lexmark 32 GB class 10. It does the job very well.
Everything I access often is on the 'internal' sd to save battery.
buy samsung class 6 32gb microsd card
its cheaper & optimum for note
I own too.
It works like a charm

UHS-I [Ultra High Speed] microSDHC card

I ordered a samsung microsdhc 32gb class 10 card but I received a samsung plus UHS-I Card. Does anyone use an UltraHighSpeed Card ? I would like to know if this speed class is compatible with our razr i before I open it. Because if not, I will send it back to get the proper one I've ordered.
Thanx.

Yeah I'm not sure on the difference myself but going by the sandisk website they call it a UHS-I card so I'd guess its the same standard

I think I did, well I'm pretty sure it does it itself when it mounts the SD card for the first time, but don't quote me on that

Because I was migrating from a class 6 to a UHS-1 I simply dumped the card contents to a folder on PC, and transferred everything - so the formatting was handled by the PC. If you were to let the device handled it.
If you were to let the device format it and used it to copy any existing content over you'd be using horribly slow MTP - much better off with a card reader.

SanDisk SDSDQUA-128G-U46A 128GB microSDXC card

Looks like SanDisk is keeping it under wraps - spoke to SanDisk support rep - he denied existance, but the info is getting spread all over the internet and some Taiwanese sites already list it in their inventory, like this one: http://www.sbit.com.tw/en/productsearch.aspx?_searchtext=SDSDQUA-128G-U46A
Making a placeholder thread for this card - please post any news here and of course links, if you see it available. I expect formal announcement from SanDisk in the next couple of months or so
I wonder how much those will go for?
a year ago, when 64GB one, the one in my signature, came out it was $229.99 on SanDisk site...Don't expect this to be any less...after all - it's double in size

Has the 64gig one only been out a year? Seems longer.

It would be much cheaper and even as effective to simply get a Ribbon adapter (microSD to SD) and buy a standard 128GB SD card with a good write speed.

That is true and you should theoretically even get better performance and data integrity from the card with the larger surface area. However there is the convenience to the micro sd of have not having to worry about possible mods to make it fit inside your case etc

Bingo- I have a ribbon adapter soldered to a Kingston sdcard. Believe me its a pain if I want to remove it to put it in an adapter to go in the PC for whatever reason. It was difficult to solder, it's difficult to fit, and just plain a nuisance overall (but I do love having my 70gb music library and tons of leftover room for videos or whatever). Even I would strongly consider getting a $200 ish 128gb microsdxc.
I don't understand what Sandisk is waiting for. There is obviously a demand for 128GB microsdxc cards. is it possible that Sandisk couldn't manage to fit 128GB on the tiny microsdxc card?(not yet anyway?)
the 128GB SDXC cards are selling quite well... I bought the Sandisk one for only $120 recently.(for use in my camera)
Its a combination of time it takes to develop the technology and making a production pipeline for it. Once its ready they're not gonna make 100 of those cards - they're gonna make 100 million of them.

It's probably pressure from the network carriers. The service providers want people using smaller built-in memory so they use the cloud more. If users rely on the cloud over local storage, there is a much higher likelihood they'll go over their monthly data cap and get charged for overage. It's likely part of the reason Apple is the only major smartphone manufacturer (that I can think of) that hasn't adopted expandable memory via a MicroSD card slot. A 128GB MicroSD card would allow the majority of people to carry their entire collection of music, videos and pics around. Bandwidth demand would drop and carriers would lose overage revenues.

Yeah but their is a shi* ton of people qho take thousands of pics and videos. Music etc. Unless they go 64GB internal or 128GB internal there is still a need.

Disagree.
Carriers aren't making the phones. Carriers do want people to rely on added data usage but don't want to over-burden data plans which is exactly what streaming 128 gigs of media would do if it weren't onboard.
My media collection is just over a terabyte still and I have no desire to try to stream that even on my unlimited data plan.
BTW, HTC is also on this 'no expandable storage' kick for some reason. I think they're just being cheap on components to maximize profit.
the delay is most likely they're still testing the card to make sure it works as expected on various devices. These cards are used in other devices besides phones.
I highly double carriers have much input into this. The memory makers are always looking for ways to add more storage and a reasonable price for profit. And more and more, mobile devices are not including ways to expand memory; then the phone can be charge for stupid amount for a tiny bit of extra memory.
Like many, I look forward to having the extra memory. I seem to blow through memory on my phone; yet, not on the tablet.
Cant wait till these are out!
I have way too much music, and to be honest, this would be great for carrying roms and kernels with me, as well as other stuff in case I have to do an emergency reflash. 128GB would be dandy to have.

I'm not super familiar with microSDXC technology, but I have a question -- how do we know a Note II will support a card of this capacity? I thought that the largest card a Note II could support is a 64GB one.

At the time that the phone was released, the largest capacity sdcx micro card available was 64gb. I suppose that theoretically, the phone might be able to see higher cards when they are released.
8 months ago I bought a SanDisk 64GB micro SD for $56. I think it has been out for almost 2 years. When the 128GB comes out it will drop in price quick. Why? Because they need to get them sold before the 256GB comes out. Then the 512GB. Then the 1TB and so on...

What really matters is that this phone supports microSDXC, so it should support any size microSDXC. All of my android phones worked with the 64gb microSDXC even though this is the first one that officially supported it.
