Does anyone know what is the MicroSDHC class speed rating of the X1?
i currently have a SanDisk Micro SDHC 8g Class4, and i'm planning to upgrade to 16Gb. is it better to buy a 16GB Class6?
4 vs. 6 that's the different

What the heck are you talking about? Any card will work on the Xperia. The X1 does not have an internal card so it has no MicroSDHC write-speed rating.

I'd take the Class6 card - needless to say my card is Class6 already

he's asking if the x1 can support those speeds or if it will be a pointless waste of money

sorry for the late reply.. yep ale07 is right, i just wanna know if there would be any difference if I use a Class 6 or Class 4 card on my X1.
well I guess I'll go for the Class6. can anyone recommend a GOOD brand? Transcend is the most common and the cheapest.. but I've read bad reviews about their products and same goes for Kingston.
I wonder why Sandisk isn't making any Class 6 cards.
i've got a transcend and have no problem with it...
i also have 3 sandisks and also have no problems
so personally i don't think branding is really that important
Prob no difference. The class rating is the MINIMUM guaranteed write speed it will do (barring any host-side issues). I have several microSD cards, all class 2 ranging from 1GB to 16GB and all of them provide over 20MBps read speeds.
Hello
I got my Legend about 2 months ago, and I have a big problem with storage space...
What is the biggest sized SD card the Legend can use?
What is the type of SD card (micro, mini, etc...)
What is SD card class?
Thank you very much
microSD compliant with SD2.0 Standard (aka microSDHC)
The biggest size available currently is 32GB.
I don't know if even more is possible with microSDHC or if bigger cards will only be possible with SD3.0 (aka SDXC) but that question is not relevant as you can't buy any greater then 32GB yet.
The Class of the SDCard is a measurement for guaranteed minimum speed in random read/write.
The Class does not provide any information about real-world speed or max speed.
For your mobile phone the class is a pretty useless criterion as you don't need any guaranteed minimum speeds but good overall speeds ESPECIALLY sequential.
The guaranteed minimum speed is important for HD Video Cameras for example where you write data all the time at a given speed (resolution).
thanks.
but I DO need class with high speed because I want to use Data2Ext...
Don't pick uSD card based on class !! class tels you MB/s for sequential write only... you need a card that is overall fast, I had 16GB class 10 Kingston and data2ext was just horrible!
Now I'm with class 4 Sandisk mobile ultra and it is in fact faster in every test I ran...
So read reviews before you buy
ye but that is exactly why im asking...
well then, I recommend sandisk mobile ultra as I have it and it is OK, there are probably faster cards...just see the small files read / write speeds in reviews those are of greatest importance
i purchased a kingston 8GB class 4 which crapped out. android kept reported sdcard unexpectedly removed. tried all sorts (formatting in windows, android, quick, long, etc).
RMA replacement did exactly the same, so i'm guessing kingston class 4's are best avoided.
If I recall correctly I have a 16GB microSDHC Class 4 card. After applying data2ext with this card, my Quadrant scores hit around 1500, which is crazy.
This is where I found my card: http://www.amazon.co.uk/SanDisk-16G...P06K/ref=sr_1_1?ie=UTF8&qid=1298984123&sr=8-1
I personally recommend this card.
witch is better class 4 or class 6?

class 6 is better , but class 10 is even better
I've got a Sandisk Ultra Mobile 16gb SDHC which works fine in the Legend. Make sure you format it with the phone to stop it being dismounted, well known issue and the fix
Hi, I bought this card and the difference between the orig is a huge, Antutu beanchmark is always at the speed measurement card hangs the phone is slow with it even after a clean format (does anyone know what with it?
sorry for my english
my kingston class 10 is also very slow, it barely makes 6mb/s write which is way below specs.
i ordered a other clasd 10 from samsung to see if there is a difference.
Dear readers,
I'm searching a for a new SD card for my HD2 for a while now and wanted to buy a 32gb class 10 microsd card from samsung.
But then i saw a new cards with new classes called "UHS".
I also saw one of them having the class 6 and the UHS class.
I have a few question regarding this:
1. Does this UHS class work on the HD2?
2. Is it possible for a card to have a normal class and a UHS class?
3. if not, are UHS 1 cards as fast as class 10 cards on devices that do not support UHS?
4. How can UHS 1 be cheaper then class 10?
adata 32gb micrsosd UHS 1: cant post url...
the same card for 22 euro's: cant post url...
samsung 32gb microsd class 10 for 26 euro's: cant post url...
I hope this topic will answer the the questions i think other people have too.
kind regards,
4rjan
Can't answer for sure if they are 100% compatible with HD2 hardware(there is certain hardware requirement for UHS), but in theory any speed after class 8/10 is pointless. Class 10 is close to HD2 hardware bandwith limit. You won't benefit that.
Nobody??
I was also looking for a 32GB class 10 card and found the UHS-i type, but in the reviews i saw said about compatibility issues in non compatible devices or transfer speeds relatively low in devices without UHS-i compatibility.
To avoid problems i purchased one Samsung Class 10 card, works perfectly in my HD2 and don't have to worry.
That is exactly what i thought, that the uhs-i has a lack of performance on not supported uhs-i devices and that they are not completely backwards compatible to normal class 10 speed.
Do you maybe have a URL of those complaints?

That would be expected for transferring relatively small files and using windows formatting as the random read/write speed (most frequently used) will be slower with a higher class, whereas the sequential read/write speed will increase. This may beneficial for users with WP7 but if you use it anywhere else it will seem much slower.

But do UHS class 1 cards run ass class 10 cards when they are used with non supported UHS devices? If it is true what you guys are saying then its not.
I can't find anything about it on the English Wikipedia, but on the dutch Wikipedia it says it runs like class 10 on non supported devices:
http://nl.wikipedia.org/wiki/SD-kaart
UHS: MB (Megabyte) Mb (Megabit)
UHS Class 1 10 MB/s (min) 80 Mb/s (min)
UHS-I 104 MB/s (max) 832 Mb/s (max)
UHS Class 2 105 MB/s (min) 840 Mb/s (min)
UHS-II 300 MB/s (max) 2400 Mb/s (max)

WHAT IS UHS-1 ?
"UHS-1" or more accurately "UHS-I" stands for "Ultra High Speed" - 1 and is a speed class for SDHC and SXDC memory cards.
UHS-I is the fastest category of card available today with a bus interface speed of up to 104 MB/s.
An SDHC UHS-I card will work in any SDHC compatible device at lower speeds, but to take advantage of the UHS-I speed, a UHS-I compatible device is essential.

the question is what are those "lower" speeds?

The speeds would be the Class 6 or Class 10 speeds, depending on what's listed on the card. Of course, even that can be bottlenecked by your device's cache.
UHS-I doesn't work nice!
I try to use a SanDisk 16GB class10 Ultra MicroSd HC-I but as I found out it doesn't feet with my HD2 EU..... ...Although it works very smooth and fast after some hour my phone just freezes....only the light of the hardbuttons works...screen turns black...I take off the battery...and all this sadness comes to my face...
So I got back to my Transcend 16GB class10 and everything works almost fine (a little bit slow sometimes, so I use sd card boost and swapper2).
You can see by yourself ...the mmc driver has not included UHS mode...
UHS vs CLASS
The UHS means it has content transfer speed of minimum 30mbps to maximum of 104mbpswhen you transfer the content from MicroSD to System(PC)....but the data write speed on the MicroSD depends on the CLASS mentioned on it i.e., CLASS 10 has MAX write speed of 10MB/S......(Note: all this speed transfer test will use top speculated system configurations so it may vary on our PC's).
Hello,
Just to echo what a few people have said elsewhere and clarify something. Using an SDcard with a UHS classification may well cause your HD2 to hang, black screen, freeze, crash .... especially when using certain ROMs. Some seem more resilient than others, but the NativeSD ROMs in particular rely heavily on accessing the SDcard. The only way to reset after a blackscreen is to remove battery and reboot.
The HD2 was never designed to work with these cards and they require specific voltages from the phone hardware in order to run correctly. The HD2 does not have such hardware. I used a Sandisc 16GB Class-10 UHS-1 card and my phone would hang/crash 7-10 times each day. After replacing it with a Class-10 Kingston card with no UHS classification, the phone runs fine. Nothing else was changed except the SDcard. The exact same installation was used by cloning the SDcard partitions. Consequently the phone runs fine now.
Just thought I'd post up in case it helps others.
Would appreciate if someone could mirror this post for me (I have less than 10 posts on XDA and don't want to spam the forum just to get them) on this thread for [ROM][4.1.2][720p] NexusHD2-JellyBean-CM10 V1.5 [NativeSD] because a few people were complaining of bugs and it's nothing to do with the ROM itself, more the memory cards they are using.

Very strange,i using a Sony 8GB UHS-1 and it works fine with all roms (dataonext,nativesd).I'm thinking to buying a Sony 16GB UHS-1
I am using SanDisk ultra 16Gb UHS-1 card without any issue for some time now with many different ROMs. I would rather bet that not original (Kingston, Sony, no names) that looks like original cause that.
guys what do you think about this card http://youtu.be/PuHfmuJ8pf0.... I am about to buy a new 32gb card for my new phone.
please give suggestions....
Hello guyz,
Can you please recommend me the best microSD card for our phone in 128GB or 256GB?
I am leaning towards Samsung Pro Plus 128GB or EVO Plus 256GB. Should I go for speed or size?
Also there is Sandisk Extreme with similar speeds and Lexar Professional with read speeds @ 150mb/s, but I'm note sure if these speeds are overkill for a Note8..
I would also like to know cause eBay has so many fake ones.
I honestly have had issues with every sdhc I've used except for the EVO's. I don't know about other Samsung classes but I personally would stick with genuine Samsung memory cards.
Sent from my SM-G955U using XDA Free mobile app
I've been using the 256GB EVO that Samsung was giving out for the Note7 promo. Been working great.
I lost my $32 for useless SD card
I wouldn't worry too much about speed, as you can install apps on the SD card (correct me if I'm wrong). I would go for size over speed.
Never had issues with the Samsung or Sandisk memory cards for mobile devices, I have used everything from 2gb cards to 256gb cards and I will be looking at the 400gb card as soon as Sandisk gets it to retailers.
Samsung EVO Plus Grade 3, Class 10 128GB MicroSDXC thats one i have in my Note8 and as i don't shot lot of 4k videos that speed is enough
400gb for the win chuck
sandisk 400gb. Note8 ready. get it ONLY from "ships and sold by amazon". never 3rd party.

Fastest is probably:
Lexar Professional 1000x microSDXC (up to 256GB)
Biggest size is probably:
SanDisk Ultra 400GB microSDXC UHS-I
Best price/size/performance? Probably Samsung Evo+ line of cards, based on the following (it's a guess, I have not benchmarked them myself):
https://www.pidramble.com/wiki/benchmarks/microsd-cards
Do not rely on only the manufacturers' ratings, they can be way off and sometimes read is fast, but write is slow (or vice versa). The most expensive is not always the fastest either. Further, some excel in big sequantial reads, others are a tad better in random read/write IOPS. Even further, Note8 card interface probably is NOT able to use the maximum speed out of the latest UHS-II cards.
And yes, do NOT buy on eBay, unless you are willing to gamble or really know what you are doing.
My experience with SanDisk
Hi,
I just bough an Sandisk microSdhc Extreme 128 GB, Class 10, U3 UHS-2.
I emailed Samsung about my Note 8 and they told me that it supports UHS-2 cards.
When running tests on phone I get MAX 60write 60read
Only on DiskSeed Test App I got 287 MB/S read and 37 MB/S write.
Any input?
I've had my 64gb SD card in my s5 before putting it in my note 8. I might be lucky, but I figured Samsung cards work best in Samsung devices, idk. But yeah, it's been about 3 years and the SD card is going strong.
Andddddd...itll probably break after this post.
Galaxy Note 8 has many options for microSD Card for it. Here I found much different Note 8 Memory Card.
Never had an issue with any Sandisk microSDCard. I have had a bunch of them and they all work fine.
I'm another using the Samsung 256 EVO that came with the Note 7 promo. It also worked fine in an S7Edge for a while before I got the Note 8.

Anyone know where to get this one at a better deal? When it comes to device storage I'm not as much concerned with speed as I am with size and having 400GB at your fingertips, on the go, is just pretty freakin' awesome.
Btw...for those looking for more speed, I happened to catch this video on YouTube the other day that explains what the different speed markings on the sd cards actually mean if anyone's interested. I found it to be fairly informative.
