Does the S7 Edge support UHS-II - Samsung Galaxy S7 Edge Questions and Answers

Haven't found any straight answer to this. Some argue it doesn't have the right connector for these cards, others say it's fine. Any first hand experience?
Also, are there any specs on the max write/read speed it can handle?
Thinking of getting this lexar in spite of some bad reviews

Anyone? Sorry for the bump

I've bought that exact microSD on Amazon in July and it works perfectly, access speed is extremely high, I've even recorded some 4K videos directly on the microSD without any glitch or video problems.

It can take UHS-II cards but does not gain the speed improvement. There is a thread somewhere where a bunch of people posted their sd card results. No performance gain over UHS-I standard.

ok, thanks. So the only benefit is transfer speed from card to pc. Good enough for me.
Does anyone know the upper write/read speed limit of the phone?

Haven't seen anyone hit more than ~90MB/s read ~90MB/s write

Hopefully the S8 will natively support UHS-II

Micro SD class speeds

I know the differences between the classes, but I'm more concerned about how the speeds effect some what I do on the phone. Currently I have a 16gb Samsung C2 that I took from an Epic. It seems to be working ok, just nothing to write home about. I am thinking about getting a 16-32gb c4 or higher. I'm just curious about what gains I would see
*would the camera be any quicker?
*I assume the gallery would be quite a bit quicker, can somebody verify?
*I use my phone as an mp3 in my car, would the lists load faster? as a player its just fine but it takes a while to load all the artists/albums, which is annoying when I am driving. I thought those were indexed but would a better card help that?
*any other daily activities that would see a direct effect?
I searched, but most people just asked questions I already knew. Thanks

I have a 16gb class 4 and I haven't noticed any significant increase in speed from a 8gb class 2 card both were from sprint don't know the name of them yet
Sent from my PC36100 using XDA App
Class 4 cards will record HD without any hiccups. Class 2 skip all day long, because they can only right at 2mb a second which is far to slow for HD.
thanks for the info.
I just put a 16GB Class 6 card in my Evo and it more than doubled the write speed and more than tripled the read speed. I had the stock SD card that came with the phone. I believe it was an 8GB Class 2 SD Card.
I do alot of flashing of new ROMs and such, so the increase in write speed is very noticable when copying files to the SD card. I use to hover around 1.9-2.0MB/sec and now I'm seeing 4-5MB/sec write speeds.

Does Shield TV has UHS-II reader?

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 am planning to purchase the Lexar 1800x and want to make sure if I can take full advantage of that card which support read speed up to 300MB/S. I'm also wondering about the writing and reading speed of original storage on 16GB version.
Nvm I contacted Nvidia support, only support UHS-I class 3.

by chance, did you ask what the maximum read/write speeds were for on the microsd slot?

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.

Based on this one ....San disk is better? I'm confused...

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

SD Card is So Freaking Slow!

I have a PNY U3 Turbo Performance 64GB High Speed MicroSDXC Class 10 UHS-I, up to 90MB/sec Flash Card. It seems to get slower with time. I mean it is literally taking me like 60 seconds to delete a few pictures. The card is formatted to portable storage. I only store music and photos on it. Reformatting offered no improvement. It is borderline unusable.
So, I benchmarked and found that my read speed is about 59 mb per sec and my write speed is 4.4 mb per sec. I can live with the read speed but the write speed is horrible. What gives?
How many pictures are you talking about, and how large are they?
128KB clusters?
I found trying to use 4K clusters in exfat was resulting in the same slowness. Reformatted to 128KB clusters and it flys (~20MB/s write ~70MB/read). Sandisk ultra plus 64GB.
I have this issue as well I have one of the fast Samsung cards. First few months worked great super fast but now takes a while to carry over a gig of pics and music. I also notice lag in loading and delteing photos through the phone
These are normal pics 5-6 MB. There has to be something wrong.

If you find any info/solution let us know.
Im thinking about running it through one of the tests that show the read/write speed, if its not up to par on that I will contact samsung see if its covered under their warranty.
Why not opt for a 128GB sd card? My Moto X Pure will be here Thursday. I have a 64GB in my old phone but I may get 128.
Has the OP tried backing up their data and reformatting the card?

Yes, I have tried this a few times and it did not help. The write speed of this particular card is somewhere between 5 and 9 mb/sec. I have used multiple benchmarking tools that all confirm the same thing. The sad thing, if you drill down into the specifications for a lot of these new sd cards there is no mention of write- speeds. I asked a question similar to my OP on Reddit and had somebody with the same card echo my issue. Terrible write speeds. I am not in the mood to buy another card with great specs only to find it performs poorly in my phone? There is still a part of me that thinks it's hardware or software related and specific to the phone. I can't quite believe that something advertised as "turbo", UHS-1, Class 10, and 90 mb/sec has an actual write speed of 5 mb/sec. It seems criminal.
^^See my post #3. I've found this card to have very good write speeds on the phone of ~14-16 MB/s, reads around 40-50. On the pc through a usb 3 card reader I can write at the speeds posted above.
But yes, unless you drill down, the marketing and advertising doesn't list write speeds. I can see why. It all depends where you'll be using it. I'll be lucky to see sustained 10MB/s read through my dash cam (not sure what the write speed even is) even through the card is capable of 40MB/s +.
I should say, using the moto x, through MTP, I've seen read speeds upwards of 35-40MB/s, write speeds of about 7-10MB. The card is faster through twrp, backup stats indicate ~14-16MB/s.

Microsd card - Which one to use?

Hi All,
Just like to ask. My S7 Edge will be coming next week and I wonder which of my microsd cards is better to use for Mobile Phone specifically for S7 edge.
I have 2 Sandisk Ultra 64GB with attached speedtest result:
microsd_x - higher read but lower in write. i'm using it on my Yi Action Camera currently.
microsd_y - lower read but higher in write. used it on my HTC One M9+
I just like to know your opinion which one will be better for the S7. Will the microsd_x is better for S7 edge since it has higher read speed that can be maximized when the phone reads the apps that i installed to sdcard? will the write speed is just enough for average daily use?
and will my action cam benefit for microsd_y since it has higher write speed and read speed will not be used most of the time?
Please help. need you advise. not sure if my logic is correct based on the speedtest results. or is there a deeper explanation behind it.
Thanks!

I think it will depend on what you use the card for the most. If it's mostly loading apps, then the one with the faster read speed. OTOH, if you mostly use it to store photos or videos you take with the phone, then then the one with the faster write speeds.
i think i will try to test the microsd card with higher read speed first on S7 edge and see if the write speed of the same card will be sufficient for mobile phone use.
The left one seems to peform far better with random IO and is fast enough for 4K recording so that's the one I'd choose unless you copy a lot of lage files to your phone mostly.

Thanks for your suggestion. that is what I'm thinking also, if the write speed is sufficient to record 4K videos. Anyways, I'm not into capturing videos and 1080p is okay for occasional videos. I think i will be using it more for transferring installed apps to microsd and the read speed is definitely faster. But with your recommendation that it can capture 4K videos, then I will be using the left one instead.
I checked the recommended samsung evo+ speeds, the left one image has similar speed with evo+.

micro SD CARD reader speed

what's the maximum speed of the micro sd card reader? write and read speeds?
I know some android phones are kinda limited. like having 20mb/s maximum speed so it was no point buying a 90mb/s one.
I would like to know what's the lg v20 limit.
Thank you

Not sure what exact limit is but there are 2 threads on here already about micro SD cards speeds. I suggest going through those to get an answer.
Also bear in mind that alot of those advertised speeds are theoretical speeds and you will most likely never see that speed under actual use. At least in my experience
if it would answer my question I wouldn't be making this thread.
