Sure, https://www.sandisk.com/home/memory-cards/microsd-cards/extremepro-microsd-uhs-ii
Read speed 275mbps
Write speed 100mbps
They're also x-ray, shock, water resistant. At least sandisk is. I don't really see the use in a mobile phone, but if I had a really nice camera I'd consider one.

Well this is the card Specifications, not the phone specification regarding external storage.
as a matter of fact, S7 does not support UHS-II that delivers those speed peaks, it only supports UHS-I, and we are yet to know if it only supports UHS-I classe 10 or it does also support UHS-I U3. in my opinion it's class 10 only, which means : do not expect more than 48 Mb/s in read speed peaks, even if you insert a more capable microSD such as the one you mentioned.

If it supports UHS-I then it should support U1 or U3. The UHS-I is the interface bus speed and it is the thing that the phone would or would not support if it had the choice.
U1 and U3 are minimum guaranteed bandwidth for writing and are a factor of what kind/quality of flash is used in the card. While it may be that the phone is not capable of more than 48MB/s, that is above the U3 rating so that would mean that it could take advantage of a U3 card. (U3 is 30MB/s minimum sustained write speed).
U1 and U3 say nothing about read speed (which is pretty much guaranteed to be faster than write speed) and they say nothing about the real world write speed which may be higher - they simply represent a promise that the write speed will never dip below the specified speed no matter how long you write to the card. Most cards write faster on average and in short bursts.
U3 is listed as promising to support 4k video recording, but it depends on the codec and what bitrate it outputs as to whether you really need U3. If the bitrate of the 4k video on the S7 is under 10MB/s, then a U1 is sufficient. If it is over that, then a U1 may stumble on longer 4k videos, but it might work if the rate is only a small amount over the limit, depending on the card. Since the only rating above U1 right now is U3, a U1 might be able to promise something between U1 and U3 and wouldn't have any way of stating that with an industry standard logo on the card, so YMMV.

So it "supports" the UHS-II card, but does it have the extra pins to take advantage of the speed benefit, or is it limited to UHS-I speeds due to UHS-I hardware?
Sent from my Galaxy S7 Edge using Tapatalk
'UHS-II support' sounds like 'compatible' to me. This is still no proof. I think the most relaible proof will be neutral speed tests with UHS-II SD cards.
I did a test with my Kingston 64 GB microSDXC UHS Class 3 UHS-I and the results are these :
Sequential Read : 72,41 MB/s
Sequential Write : 38,09 MB/s
Random read : 8.09 MB/s
Random Write : 0,56 MB/s
Internal memory :
Sequential Read : 483,43 MB/s
Sequential Write : 141,12 MB/s
I think the sequential write of the Kingston SD card in not that bad. I have a S7 Edge.
Looking at the results from the first post in this thread: http://www.swedroid.se/forum/threads/vilket-minneskort-koer-ni.131343/ it seems to be UHS-I only (see attachment) 128gb 1000x lexar.
Seemed to perform surprisingly bad also though considering what type of card it's supposed to be.
i'm on ebay hunting for a 64gb sd card (i think if you want a fast U3 128gb sd card its too pricey) i'm hesitating between a samsung PRO or a sandisk extreme, both are showing write speeds of over 80 mb/s

These discussions should really be focused in our microSD accessories thread: http://forum.xda-developers.com/s7-edge/accessories/suggestions-microsd-t3321569
Your first link mentions that the card they are reviewing is a UHS-II card and has nothing to say about the actual slot in the S7. The closest they come is that (paraphrasing) "you'll want the fastest performing card for your new flagship device".
The second link was hard to read even with google translation, but it appears to be the same bunch of half-baked information. Someone "confirmed" that UHS-II cards are supported - which is nothing more than a confirmation that those cards are backwards compatible. They also post some benchmarks which confirm some of the benchmarks in our own microSD thread over in the accessories forum - that the Lexar UHS-II cards are not benchmarking any faster than the best UHS-I cards and both are well below the bus speed of even a UHS-I device (with read speeds topping out around 70MB/s, well under the UHS-I bus speed of around 100MB/s and those same cards benchmark over 90MB/s for UHS-I and higher for UHS-II in a desktop or laptop).
The slot in the S7 does not appear to implement UHS-II speeds and doesn't even appear to max out UHS-I speeds. You are best off only spending extra money for a UHS-II card if you have plans to use it outside of the phone as well (such as remove it to plug it into your computer with a UHS-II card adapter to download new media onto it periodicially)...

Hi guys,
So I recently got an Acer a500 and was wondering what the best MicroSD card I can get for it is. I was thinking about a Sandisk class 4 32Gb SD Card. Is that good? I'm looking for a card that will be fast for supporting apps to SD Card. I also heard Sandisk is the best SD cards for Android. Would a class 10, 16Gb be better? I seen one but not Sandisk. Thanks for the help.

There is no such thing as "best" as there are several dozen manufacturers selling cards, and still almost all the flash chips on them come from the same factories. If you want speed then obviously class 10 is better than class 4. Just make sure you don't buy one from eBay or such as those places sell fakes for suckers who do not know how to check if they are fakes or not.

SanDisk Mobile Ultra Class 6 32GB
I'm going for the SanDisk Mobile Ultra 32GB it's a Class 6 30MB/s depending where you are checking you can find it from 43 euros (amazon.de) to 100e, I think it's the fastest, I use SanDisks in all my devices, DSLR, mobile etc, most reliable so far. Not sure why Samsung for example calls its card a Class 10 if it's 24MB/s
Class is the write speed, like class 10 is 10 MB/s. The class bits can't go higher than 10, so it's a limitation of the SDHC specs. The read speed can vary though, so a 30MB/s read means it could probably write that fast, but it can't report over 10. It's set to whatever the mfg thinks is reliable for write speeds.
New interfaces are using UHS (50 MB/s r/w), DDR UHS (95 MB/s) while still calling it class 10 for older compatibility. Then there's UHS-2 which is 4x that.
Sorry to hijackthe thread, but we can go up to 64GB on the iconias, right?
Nope. 32GB is the limit for SDHC. SDXC goes to 2TB, but the Iconia is only compatible with SDHC.

Oh yeah! My mistake.
Update: It is actually a UHS-I class, just read the description more carefully!
I'm using the Sandisk 64GB SDXC in my A501 and it works fine. I only had to format it in the PC to NTFS.
Sent from my A501 using xda premium
Interesting! What does it show for total space after NTFS format? If it's SDXC compatible, it should be able to handle anything up to 2TB.
It says total memory ("Gesamtspeicher" in German) is 59.46 GB.
I have copied many movies on the card (now only about 14GB empty space is available) and all files can be accessed fine.
It would really be nice to know if this means that we even could use cards above 64GB once these will be available...

SDHC-standard supports only up to 32GB cards, SDXC-standard supports much more than than but A500 does not support SDXC. So no.

There's no reason that it should have any trouble if it can handle 64GB as SDXC and NTFS have an addressable range of 32 bits x 512 (2TB). It's similar to switching from a 16-bit CPU to a 32-bit CPU. There's no 17-bit CPU.
It's hard to believe this has an SDXC interface though, but then the difference isn't as much hardware related as SD to SDHC.
I know that the A500/A501 should not be able to handle SDXC cards.
But at least my A501 does it very well with the Sandisk 64GB card. For everybody with doubts I have attached some proof.

i to have put a 64 gb card in my tablet. It does work . I Have the card formatted NTFS. In 3 partitions.. i actually bought it to use in a windows tablet that i no longer own.
In my iconia i now keep a class 10 16 gb card that is PNY BRAND....I see No reason for anything larger.. With what i use my tablet for no reason to be bigger. the 64 gb card was over 100.00. but got on amazon with a gift card from another site...I also have a 1.8 micro drive. that is 128 gb .. that works awesome thru usb port.. I forget the brand as its in a generic case. i think its a Toshiba drive..Not looking while writing this as its in my purse downstairs...

I actually have a very neat portable hard drive in my phone: it has 32GB internal storage plus it also can be expanded with an SDHC card. And the phone can act as a regular USB drive, so it can be plugged to A500 or whatever. Terribly handy.
Yeah, I don't think I'd buy one right now at $3 per GB or even $100, but that's great news for the future when 32 is considered too small to be useful
I search around website but couldn't find the specific specs for the micro sd card reader for Shield TV. Does it support UHS-II?

I assume all the card reader of UHS-1 class3 should have same limit...based on the wiki the limit for that is 104 MByte/s.
I did some further research and seems like random writing and reading speed is actually more important than sequence speed. However, the review on amazon shows Samsung pro plus is best on both random and sequence speed so I guess I will just go with that for now. Laxer is actually only good at reading speed.

thats a pretty misleading article, there compairing a 128gb evo plus to other various sized cards. from what ive seen (so far) all premium 128gb cards have relatively low write speeds vs their smaller counterparts.
lexar's generally have the best sequential read/write speed, samsung's usually are better with random read/write, and sandisk is definitely solid too.
for example
lexar 64gb 633x sequential read/write 93.36 / 48.09 MB/s
lexar 128gb 633x sequential read/write 73.17 / 22.16 MB/s
results are basically the same for other manufacturers.

Definitely a fast card read/write was a bit faster than 80/40 MB/s iirc.
I haven't ran any legit benchmarks on shield yet, but regardless of the sd card i haven't really seen write speeds over 12-15 MB/s while transferring from internal to sd with file managers, ES specifically.
So im thinking internal storage isn't particularly fast, just like on the shield tablet. If i get bored I'll run some tests and see what I come up with
I haven't found a device that's not a camera that support this format yet.
^^ yeah pretty much. even if they call it out. real world speeds dont seem to get there. outside of HD cameras
The microsd reader is UHS-I so you will spend money for nothing. No matter how fast the external storage is you still depend on the speed of the internal storage which is gong to be the bottleneck when you run the OS and apps. 4K video needs 25Mbps and UHS-I can deliver easily. Same story if you read from USB 3 ports. I don't know the speed of the internal storage but it should be at the commercial level of the beginning of 2015.

What's your read/write speed with the pro plus? I got the same, I get 60~ r/w.
I ordered 500gb version...I did get the card for my phone lol but like 40s speed sad
It's a 8GB/1GB version.
The pictures speak for themselves. The Sdcard is PNY Turbo Perf 32GB. The left picture was taken when the PNY was formatted as internal. The internal card performance result in the 1st picture seems misleading, it's actually my sdcard, not the real internal flash memory of the phone.
I believe the sdcard encryption (don't be confused with device encryption) in Android 6.0 deliberately takes away ~50% both read and write performance of my reasonably fast Sd Card.
I am thinking about going back to 5.1.1 where I can move my apps to external storage without any performance compromise.

Buy it from a reputable source if you buy it online, it's also the most counterfeited card. Do a search and you'll find that they even make the packages to resemble a Sandisk package. I purchased a counterfeit card from Amazon once, but they made good on it.
i have 31 MB/s read and 36 MB/s write on internal memory with a SanDisk Extreme PRO 32GB U3
I was really surprised when I got the slow SD card message with a brand new Sandisk Extreme card formatted as internal memory.
I thought pretty much everyone got the slow SD card message, especially since other Marshmallow devices with SD card support had reported that quite a bit as well, and it was just a bogus warning message...
On the 3 G3's I have using Sandisk cards, I've never seen that message. I didn't know that message existed until this thread.

To be clear, we are talking about using Marshmallows "adaptive storage" feature, in particular selecting "internal storage", that is resulting in the slow sd card message. Are you using this same exact feature as well?

I think this might be a problem related to the microsd card interface that Motorola uses on it's low to mid-range phones rather than anything to do with the microsd cards themselves. All of the SOCs that they use (Snapdragon 200, 400, 410) support SD 3.0 (UHS-I) speeds, but I read somewhere that Motorola cheaped out to save costs and used a slower physical interface that severely limits read and write speeds. I can't find a link at the moment; I thought it was on Anandtech, but I'll update the post if I find it. I get this same message on Condor and Surnia.
yeah
performance of SD card is affected
Moto G 3rd Gen Stock w/ Sandisk Extreme Pro UHS-1 U3 = 34.25MBps Read & 49.49MBps Write

You guys do realise there are different classes of SD cards right? There's generally a little number in a circle on the card, most commonly a 4 which is relatively low performance in comparison to speed class 10. Then you have the UHS variants of speed class 1 and 3 which are ultra high speed and the number is inside a little U on the card.
SanDisk Extreme should be a UHS 3 card.
EDIT: Results with a SanDisk Ultra Class 10 Card (5.1.1 16/2 GB)

10 stands for min 10 MB/s
UHS 3 is min 30 MB/s so your card is almost meeting that.
Then there is also UHS-I and UHS-II which might be not supported (specially UHS-II which requires extra pins).
EDIT2: The SanDisk Extreme card should also be a UHS-I card so it seems that the Moto G3 doesn't support UHS-I or/and UHS-II.
I biyed sandisk extreme 32gb sd card for marshmallow update,only 20 euro in germany,class u3,and working perfectly by me.With my old card class 10 phone lags alot.
I've read that with Samsung Phones, Samsung SD cards work perfectly with.
but which one? Samsung Pro Plus or Evo Plus? is there any limitations on what SD card I can put on the s7?
Evo Plus has Read: 80MB/s Write: 20MB/s
Pro Plus has Read: 95MB/s Write: 90MB/s
Price doesnt matter.
thanks
I just bought a pny elite performance card from pcworld. £39.99 tested at 68MB/s read 52MB/s write in the s7. Will do for now!
Samsung Pro Plus is one of the fastest card out. Last week Samsung had the 64GB for $35. I'm waiting on for that price. No rush for me to get one.
Samsung Pro Plus or you can get the 128GB Lexar 1800x that has fast UHS-I speed like the Samsung yet also has support for UHS-II for *much faster* speed when using the card with external USB3 for transferring files. Am using the Lexar 1800x INSIDE the phone and transferred many GBs of files fast. Naturally if I used the card outside the phone environment (read: in the USB 3.0 adapter) it would have been about 2x to 3x faster. The Lexar 1800x is the fastest card out there right now, will handle the next gen when phone support UHS-II, and... if you're like me and have the need for speed
They also make a 64GB version.

Awesome can you post your read write speeds? I was considering this card. It was this or the new Sandisk with UHS-II.

A site says, "The Lexar 1800x microSD card was tested in several UHS-I and UHS-II card readers. In UHS-II card readers the 1800x microSD card reached 272.3 MB/s sequential read speed, just passing its 270MB/s quoted read speed. Sequential write speed measured 222.2 MB/s, slightly less than the 245 MB/s rating. In UHS-I card readers, the 1800x card reverted to UHS-I mode and was limited to 96.5 MB/s read and 77.5 MB/s write speeds. Still fast, but not quite as fast as the fastest UHS-I microSD cards." Have not tested it in the phone yet it seems very fast.
Here's another site review diff than the one above http://www.realhardwarereviews.com/lexar1800x/7/

PS: If you never see yourself using UHS-II and just keeping the card in the phone then the Samsung card is probably best bang for buck. I move some big files around (pro video and pro audio both in pure lossless) so being able to use the card via USB 3.0 makes life easier plus the next gen of phones might support UHS-II and thus I can keep the existing data on card and not have to data migrate.

I actually want to know what kind of speed the S7 gets with this card in it. From some other post I read someone was saying the reader in the S7 is not that great.
I did a test and it was around 70 read and 60 write. Seems the bottleneck might be the phone as saw another test with the SanDisk Extreme Pro on XDA and it was about the same speeds. Keep in mind that, for me, Lexar 1800x will also be used outside the phone environment so the UHS-II will be very useful. YMMV.
What happens when you insert an 256GB Sd
Officially Samsung says we can expand upto 200GB of external storage but unless Samsung intends to make 200GB Sd card, there aren't any of those kinds in the market. i want to take full advantage of the expandable memory but 126Gb won't be enough so your opinions would help greatly. Can pop in a 256Gb Sd card
So I went and bought the Samsung Pro Plus 32GB. hopefully comes here before my S7 Edge
Good choice of card. I have always used Samsung cards with no problems. Got my Edge yesterday. I've had a bunch of phones, including the latest Iphones and this tops them all easily. Enjoy.
This is all being discussed over in the accessories forum, we should probably continue the discussion over there...

Still confuse which SDCard to go for for my s8+, little searching on Google shows me that Sandisk Extreme 128GB U3 MicroSD Card is the fastest, any suggestions?
As far as I can tell (since we have to guess due to samsung failing to provide proper details as usual), it doesnt support UHS-II or UHS-III (275mb speeds). So you may as well get a standard UHS-I card that does around 90mb. Saw a guy test a 275mb UHS-II card and it only got 60-70mb speeds in A1 SD bench, the same as my 90mb UHS-I card does. I have yet to see anyone do any better than about 80-90mb speeds.
Considering UHS-III came out only recently it makes sense the phone doesn't support that.
I went out and bought a UHS-II card though and I'm only getting UHS-I speeds, so I can confirm that the bus in the phone is ONLY UHS-I.
What are decent UHS-I speeds? I'm getting just 40mb/sec on read and 20mb/sec on write

UHS-III was releasedin Feb yes.....UHS-II was release as part of SD spec 4.0, and considering 4.10 came out back in 2013 I see no excuse for not supporting that at least, it allows speeds up to 312mb full or 156mb half duplex, MUCH higher than anything a UHS-I card will ever do.

I agree with you there. I really wish it was a UHS-II bus at the least.

If it's giving you the speed which is mentioned in the specs then it means S8 supports U3!

I didn't check in ny S8...crap.
My note 7 was close to as advertised though 240ish read and around 90 write if memort serves me. When i get my new S8 ill check.
But besides the speed tests i have 55gv of pictures on that card and when i browse my gallery they all load immediately when i scroll. No other card ive ever used would do that Id see lots of white black squares lol

That would mean the note 7 supported UHS-II. UHS-I maximum bus speed is 104mb regardless of read or write, the same speed the S8 supports, and that means something like a theoretical maximum 95mb or so which is why you won't find a UHS-I card quoting a higher speed than that. I don't know if the note 7 had UHS-II or not (I don't think it does and I can't find any info on it either way), it's possible given it's larger size I suppose but if the note 7 was only UHS-I then there is no way it could do anything remotely close to 240.
Speeds
How are you guys testing the speeds on the cards? I have the one that Samsung sent me with my Gear VR and all that... Just wondering, I really don't think I use it enough for anything anyhow.

Its not touching 80 or 90 in any case I think may be Sandisk one is faster as compared to Samsung's card!

I get 60-65 read and write on my 95/90mb r/w sandisk. The very firts time I put it in and tested it I got about 80. It's a 128mb card and only has about 4gb used on it but I can't get anything aboe about 65mb ever since.

Same card as mine but I have the 128gb. Similar speeds too. I think that is about the best we will get on these phones, topping out around 65mb. Although the sd card speed ratings are based on perfect scenarios and we probably shouldn't expect them to hit 90mb, I don't think the phone is capable of going any faster than about 65 anyway, that is the fastest I have had on it and am yet to see anyone with higher.
