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.

I'm using a 16gb class 10...................fast
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.

Is that a MicroSD card or Micro SDXC card?
Transcend 8 GB Class 6 ordered off amazon for 10£, can be locked, thanks
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?

i've bought two of them off amazon, both haven't lasted 3 months.
Wife's htc stock (sandisk class 4 8gb) over two year old is still good. Heck, she used it with her touch hd.

Honestly, I hope you are more than just wrong... the feedbacks on this were 4 1/2 stars there, so I guessed I cannot go wrong... well, I will see
is there a software/app to check speedness of my SdCard?

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.
Just got a new card and did some read speed tests in HD Tune:
Sandisk, SD, Class 4
Read: Min 8.3 / Max 15.2 / Av 15.2 MB/s
Sandisk, microSD, Class 4
Read: Min 4.8 / Max 7.6 / Av 7.1 MB/s
Samsung, microSD, Class 6
Read: Min 7.8 / Max 15.1 / Av 14.6 MB/s
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)

Okay I got 32mb/s for Read and 13mb/s for Write.
Hope that helps.

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.
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
hi, sorry for my english.
