Only reason I bought a 400GB card was for my Switch

Thanks all for the response, I went with the Samsung 256GB EVO Plus Class 10 UHS-I microSDXC U3.

[Q] read/write speed on extra SDHC storage for DS7?

What is the max read/write speed on the SDHC slot for the DS7?
I saw Amazon's gold box deal of the day for $20 on a Kingston 16GB card with 20MB/s read and 15MB/s write speeds. & I am sure there are other/better deals on there for SDHC cards but it made me question what is the speed on this DS7 reader?

[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

Can i use microSDHC 16gb ?

I dont know wether my galaxymini support SanDisk Mobile Ultra MicroSDHC class 10 16gb/ Micro SDHC (TF) 16GB SAMSUNG Pro UHS-1 Class 10 or not ?

thanks guys! I've used both kingston and sandisk but only up to 8GB. I'm concerned if the 16GB SDs from them can still perform well and I'm still looking for a class 10 though. It was always out of stock in the stores here.

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

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.

[Q] Which microSD card will maximize performance on the Xperia Z1

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?

PS: Is not a problem of the OS, if you se Internal memory reach 70mb/s with Android, is the limit of Z1 Hardware for external Sd cards.

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.
PS: Saying all that it'll probably die on me now

I was referring of which apps did you use to test the cards, but I figure out anyway, my attached pictures are from same apps as yours in the last post.
Not really, when was the first time of the release of Sandisk SDXC 64GB Ultra many had this problem, the cards was faulty. I remember well, was all over the internet.
Samsung SDXC 64GB Ultra-Pro UHS-1. Speeds 70mb/s in reading, 20mb/s in writing

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.

I get twice the write speed as you, so if I am transferring 40GB of mp3's up you will be waiting quite a bit longer than me, I think my $30 extra cost out ways my waiting times
