I was using a Sandisk Ultra 64Gb micro SD card that was getting like 30 Megabytes per second read performance and 10 write according to A1 SD bench.
I just got in the mail a Sandisk Extreme Plus microSDXC UHS-I card and according to A1 SD bench on my Note 10.1 2014 it gets like 18 megabytes per second read performance and 20 for write.
I put my Sandisk Ultra 32GB micro sd card in the Note 10.1 and it got similar #'s to the Sandisk Ultra 64GB 30 meg per second read, 9 write.
I tried the Sandisk Extreme Plus microSDXC UHS-I card in my Galaxy S3 phone and it got like 50 Megabytes per second read, 20 write.
I don't understand why the read performance is so bad with the 64 GB card that is UHS-I on the Note 10.1 2014.
If anyone else has a Sandisk Extreme Plus UHS-I 64 Gig card, can you please run a benchmark with A1 SD bench and post your #'s?
Thanks
This might be of no help but I have a Samsung 64GB Class 10 UHS-1 Grade 1 and it works a treat. I haven't done a speed test but its pretty fast.

Could you please download A1 SD bench from google play and run the SD benchmark? The APK is only like 900 Kilobytes.
I looked through A1 SD benches reported results on the Galaxy Note 10.1 (2014 ediition) Almost every returned result I could see was 20 megabytes or under for read speed for 64 GB cards, and 10 - 20 megabytes per second write speed.
I saw a couple Sony devices that had 40 + meg per second read speeds. At this point my Cell phone (S3) with the same card can read from it over 100% faster. So I wonder if it is a Galaxy Note 10.1 (2014) bottleneck with the micro SD card slot with certain cards.
Edit:
I also did some comparing opening large PDF's on my 64 gig Extreme Plus card vs the standard 32 GB Ultra.
Large PDF's open much faster on the 32 GB ultra. 2 seconds vs 9 seconds on some large PDF's (500+ meg)

Yes thanks. It matches the #'s pretty close that I got for my Sandisk Ultra 64 GB card.
To recap in a Galaxy Note 10.1 (2014 edition) performance after several tests with A1 SD bench (using accurate with reboot advanced settings test for each):
Sandisk Ultra 64 GB card : 30-33 MB/S Read performance and 7-9 MB/S for write.
Sandisk Extreme Plus 64 GB card (exfat or fat32): 18-20 MB/S Read performance and 15-20 MB/S for write.
Sandisk Ultra 32 GB card: 30-32 MB/S Read performance and 9-11 MB/S for write.
I also tried my tests on stock firmware and flashed with cleanrom 2.0 R2. My results were the same.
In Samsung Galaxy S3 phone the same cards from above tested with A1 SD bench (using accurate with reboot advanced settings test for each):
Sandisk Ultra 64 GB card : 32-33 MB/S Read performance and 7-8 MB/S for write.
Sandisk Extreme Plus 64 GB card (exfat or fat32): 51-52 MB/S Read performance and 19-21 MB/S for write.
Sandisk Ultra 32 GB card: 32-33 MB/S Read performance and 9-11 MB/S for write.
If someone else has a Sandisk Extreme Plus 64 GB card, can you please post your #'s on the 10.1 2014?
Thanks
I just got a Lexar High Performance microSDXC 600x 64GB... 33 read 16 write. . Am watching this thread... Interested in a better performing card also.
You can't test within an 30mins-1hr of powering-on the device; the Media Scanner runs right after boot enumerating the SD-Card and will cut into your benchmark numbers.

Hello,
My mSD card just died on me, I had 16gb class 2, so I have decided to buy a new one, so my question would be, which CLASS would be the best, and full usable on phone. I mean, if I'll get Class6, will I use the full potential of it on my phone? Or would Class4 be good enough? I am using A2SD, so the speed of the card is essencial for me, but I dont want to buy Class8 if I wont be able to use it on full potential.
thanks for help
I am using the " Transcend microSDHC 8GB Class 6" and it works pretty fast.
I think it's a big difference with a class2 SD Card.
Class 6 is the highest a MicroSD card can go. There is a class 10 but that's for SDXC cards for use with HD video recording etc.

Class 10 cards are really expensive most time. I also heard that sometimes classes don't matter. If you are using a class 4 (high quality) and a class 6 (low quality) the class 4 would be faster. But it's not always this situation.

Look at my sig for a pictural definition of what i use
Speed classes
I bought a class 6 MicroSD card, because the stock SD was defective. It is a huge leap forward!
Class 2 = 13x rating = Read (Mbit) 16.0 / Write (Mbit) 16.0 = Like 2MB min. R/W
Class 4 = 26x rating = Read (Mbit) 32.0 / Write (Mbit) 32.0 = Like 4MB min. R/W
Class 6 = 40x rating = Read (Mbit) 48.0 / Write (Mbit) 48.0 = Like 8MB min. R/W
Class 10 =66x rating = Read (Mbit) 80.0 / Write (Mbit) 32.0 = Like 10MB min. R/W
So, the x rating is equal to 1.2Mb/s (Like the standard CD-rom speed)

The question was actualy, if the Desire CAN use those speeds, I mean, can my Desire be writing 6MBps? or can it read same speed as the best SD card?

Yes, the Desire can use the speeds till Class 10 (And maybe faster) WITH big files. A time back I red a comparison and difference between Class 4 and 10 was with largest file almost 10MB+ faster (for the Class10) But with small files the classes doesn't really matter, 4 or 10 Class cards will be even slow because the Desire HW is the bottleneck!

exactly what I needed, so basicaly, for a2ext it doesnt really matters, and the apps will be loaded equally from class2 or class6, since those are very small files, right?
to my experience, d2ext has shown quite improvement over class 6 card
Get a good quality, high capacity 16GB +, class 4 card. that should do for you for a good while.
I am looking forward to getting a class 6 sandisk microsdhc card for my soon to be bought tablet "Iberry Auxus AX 02" I would be basically using it to carry 1080p video files and running them smoothly. will a class 6 card be sufficient or do i need to look for a class 10 transcend.
Buyer's site lists read speed of sandisk as 30 MB/s and transcend's write speed as 10 MB/s. Suggestions please !
Buy class 10!
Buy a class 10 SdCard. Expensive but good!
better go for class 10
Can anyone comment yet on the speeds they are getting with their internal microsd cards for read and write?
I would like to see if it is worth splashing out on an expensive high speed card, or because it is running USB2 that in real terms it is crippled to about 20MBps read/write. It would be a pitty if the speeds are crappy, as samsung is making some pretty sweet microsd cards these days.

ooops. you are right... a1 sd bench labels it wrong. It says Internal SD card as my external and my internal as my external. (Sorry)
Here's my new results - reading 40 MB/sec 14 MB/s write..
Once again - sorry about that.
Guys, when you say Class 10 you aren't really speaking to the speed of the card. There is a wide range of speeds in cards that are all rated as class 10. Samsung has some that are 90 read and 80 write for example and most only advertise as 30 read and don't even say their write. Anyone have one of Samsung's good 90/50 or 90/80 cards they have tested?
I have just benchmarked a 64GB Samsung Pro MicroSDXC card (rated at 90MB/s read, 80MB/s write). In a USB 3.0 card reader on my computer it writes at around 65MB/s average and reads at upwards of 80MB/s.
In the Tab S 8.4 (Wi-Fi only model) it benchmarks at 49.53MB/s read and 24.53MB/s write in A1 SD Bench
So what would anyone say... Is the best card for this particular device? Any recommendations?
If you're not planning on taking the MicroSD card out of the tablet in order to transfer content onto it, then you might as well just go for a mid-range card as it will be limited by USB 2.0 transfer speeds anyway. I'd say the Samsung Evo or the old Samsung Pro card would be fine depending on pricing.
I dont plan on taking it out. Since the above Benchmade had the pro at 49.53MB/s read. I feel It's just going to be overkill. Since its not getting the full 90 MB/s read 80MB/s write. I'm thinking the Evo should suffice. What are your thoughts?
I meant the old Pro model, which I think was 70MB/s Read - 20MB/s write, these can sometimes be had for similar money as the new Evo. I think you'd be fine with either of those, or even the Plus model. I think the Samsung MicroSDs are fairly reliable in general.
So nobody knows if Tab S has standard bus, high speed bus or Ultra High Speed Bus UHS-I or UHS-II?
I think that micro SD card Class 10 U3 guarantees minimum 30MB/s. So it supports even 4K recording...
But I still don't know if it is worth of a lot of money. If benchmarks are true - Tab S has UHS (your 45MB/s). If!
bus speeds

According to Samsung support, the Tab S micro SD speeds is limited by the USB 2.0 bus, or 60 MB/s. So that would imply UHS, though the 90MB/s cards would not get the full speed. I would like to see someone test a 90MB/s card and see what the results are. Probably just going to go with a 48MB/s card if there isn't any difference. Though I think write speeds are significantly different between the higher speed UHS-I cards and the lower speed ones (50 vs 10 MB/s write I think).
If anyone has a couple cards and a Tab S they can test with, I would love to see the results.
Hey, has anyone used UHS-1 compatable sd card, I was thinking of buying Samsung MicroSDHC 16 GB Class 10 Evo.
Presently I use Scan Disk Class 4 , which give Read/Write speed as 15.07/5.01 on A1 Sd Benchmark tool
Please post your card details and read write speeds.
My main aim is to be able to play games without lag while using folder mount
I own Kingston 16gb class 10 UHS-1 and it is running normally, in comparison to Kingston class 4 4gb it is lightning speed according to Antutu, since i got higher grade
I know, this is probably a silly question, but am I the only one that notices how devices only tend to label compatibility with Micro SD cards based on size, and not speed or class? For instance, my Galaxy Tab S2, it simply says it can take up to a 128gb SD card, but it does not say what speed it will work with.
The reason I ask, is that I am now in the market for a 128gb card, and yet I don't want to buy an expensive fast one, if my tablet will not be able to take advantage of the premium speed. Anyone have any thoughts?
I don't know about the speed but I have a SanDisk 200 GB that runs fine.
I think that any phone or tablet that will read 128 GB will also work with 200 GB.
Shofar
Don't worry
Any MicroSD card will work in your Galaxy Tab S2. But then, you might have to format it. When you buy the card, keep an eye out on the speed class- higher speeds are much better!
You are looking for a 128GB card, and I use one in my tablet so don't worry. It will work! But I seriously recommend a higher performance card because it can get very slow with cheaper cards.
Hope this helps!
I just tested a regular class 10 card and a UHS-1 card. Both tested at 9mb write and 40mb read. The same UHS-1 card tested over 40mb write using an Odroid C1 board.

No, that means that "class" classification is outdated. Fast cards (read and write) bear the UHS-I "U3" classification, "U1" is slower.
In future, only buy U3 cards, like the SanDisk Extreme family.

I guess you missed the part where I stated that the UHS card had a write speed of 40mb using the Odroid C1 board. Obviously, when it only writes 9mb in the S2, then the S2 itself doesn't support the higher speeds. So, no matter ability the card has, if the device's bus doesn't support the higher speed, then the card's ability is meaningless. Any card you use is going to be limited by the bus speed of the device.
Paying extra for a better card is pointless if the device doesn't support the higher speed.

This was what I meant, I'll make sure to buy a decent one but not the "best". Quick question, how are the internal memory write speeds? Actually, what card should I get then? How fast is the internal memory write speeds? Thanks!
Just tested the 32 GB SanDisk Extreme (U3 but not an Extreme Plus or Pro) in my T815 with the "A1 SD Bench" app:
read 59,70 MB/s or 61,04 MB/s, write 22,75 MB/s or 24,70 MB/s. The second numbers are the result of using the "accurate mode" of the test app.

For our fast S2, this one is too slow in writing. Class 10 means only fast reading.
You better choose a Samsung or SanDisk with the "U3" designation, which means fast writing, like this:

FOR EVERYBODY :
I have bought a LEXAR 633x 200GB !!!
And it works !
Speed : read 95Mo/s write : 40Mo/s
For 90$, it do the job very well !
The only better sdcard is the 256GB SAMSUNG but it's out of price !
So a higher performance card or 200GB eill make the tab s2 go faster then? What amount of storage and sd card do you recommend?
It won't make the tab S2 go faster. But it will allow faster read/writing to higher performance sd card compared to a regular one. The S2 can only go as fast as it's hardware can, with or without a microsd card.
Figured I'd share my results with my 2015 S2 8.0 (SM-T710). Right now I have a Samsung EVO Pro (U1) 64GB in my tablet and it does ok, but I'm just about to upgrade it to a new 128GB EVO PLUS (U3) card so got some results below. Note the previous 32GB card I had was waay worse, much older and only did 4MB/sec on writes (forgot the brand) but things have at least come a long way in the years since.
Results as follows...
Samsung EVO Pro 64GB (U1) - 70.53MB/sec Read - 72.86MB/sec Write (Fresh Format)
Samsung EVO Plus 128GB (U3) - 69.91MB/sec Read - 43.40MB/sec Write (Fresh Format)
Samsung EVO Pro 64GB (U1) - 70.07MB/sec Read - 17.81MB/sec Write (Only 4.9GB Free)
Samsung EVO Plus 128GB (U3) - 63.08MB/sec Read - 27.12MB/sec Write (Only 65.9GB Free)
For the heck of it tried the transfer rates on the PC for the 2 cards as well.
Samsung EVO Pro 64GB (U1) - 86.85MB/sec Read - 80.77MB/sec Write (Fresh Format)
Samsung EVO Plus 128GB (U3) - 87.04MB/sec Read - 82.27MB/sec Write (Fresh Format)
Though got to say while cards neck and neck, small file writes where 5x greater on the new U3 card (.5MB/sec vs 2.5MB/sec) on 4k writes.
