[Q] NTFS, FAT32 or exFAT on my microSD? - General Questions and Answers

Hi,
I have a ADATA 8gb microSD type 6 and I was wondering which file system I should use (NTFS, FAT32 or exFAT).
Can't find a clear answer...
tnx!

Format to FAT32 this is most supported by devices system.

thanks ! That will do

ow.. what about allocation unit size ?

Use default ;]

thanks again!

I've read that fat32 considerably reduces read and write speeds on our microsd cards. What's the downside of using ntfs, which I've heard is much faster?
For example I've bought a Sandisk Ultra Mobile II 32GB MicroSDHC card with 30MB/s read and write speeds on paper. However when using fat32 I'm only getting 12MB/s write even when directly inserting the card into my laptop. This is while transferring 2GB files.

64GB SDXC now being recognized.

Disregard
So did the 64GB SDXC work or not? I know there's been some conflicting information on here before as to whether or not it actually supports SDXC cards.
Yes it works.
Format it to NTFS and it will work. (Takes a while though)
Card is an Transcend SDXC 64GB SD card in the dock.
Sorry for the delay.
My total storage is now 128GB

Compatible/Incompatible MicroSD/SD Cards

Had some problems trying SD cards and MicroSD cards for the Infinity/Prime docks/tablet. Thought I would share them so others could also update and post their compatibility issues.
PNY 16GB (MicroSD) / 32GB (SD) Pro-Elite: Status: Incompatible: Formated with Fat32/NTFS and exFAT. All three had no problems reading from the card however writing any files completely locked the tablet up at the 90MB mark causing it to force reboot. Tried 2 cards purchased from Best Buy (16GB and 32GB) on both my Prime and Infinity tablets/docks both had these issues. Card is rated for 35MB write however I found no circumstance using my PC to copy files to where I got over 10-11MB/sec. Read sat at around 21MB/sec.
Sandisk Ultra 32GB (MicroSD, (Docked with MicroSD Adapter)): Status: Compatible: Formated with Fat32/NTFS and exFAT. All three work great reading and writing on the tablet. Writes were a steady 22MB+, Reads just as good. I assume once the I/O bottleneck is fixed this will improve, as it sits on the PC I get around 30-40MB write, 55+MB read (burst). Writing a 3GB file ~ 15-20MB wite.
I should mention I was using a USB 3.0 card reader to read/write when testing on the PC.
Please update this thread with your cards you have tried so others like me will not have to return to BestBuy 3 times to finally get a compatible card.
Thanks!
Might the incompatibility be caused by card class?

It is possible however I have not tried any other cards from any other brands.
The PNY is listed as: SDHC Class 10, UHS-1
The SanDisk is listed as: SDHC Class 10 UHS-1 so they seem to be exactly the same class.

I also bought Sandisk Ultra 32GB Class 10 micro sd to be used on my phone Xperia Mini, i find my phone to be very slow, does this means that my phone is incompatible with this card.

I do not know how you formatted it, and which filesystem(s) your phone supports. I'd set out my question in the Experia forum(s).
I bought a 64GB Samsung microSDXC UHS-I card pro class 10
http://www.amazon.com/Samsung-micro-UHS-1-Class-Galaxy/dp/B00AK31M3G
And it works great, havent had a problem with it, I tested it through a sd card slot with sd card adapter and I got a constant 16-17 mb/s write speed with files bigger than 5 gb. I also tried formatting in exFAT and NTFS, and both work.
I hope this clears up some doubts about UHS-I cards. Or at least doubts about this card.
I also bought the SanDisk Ultra 32GB Class 10 microSDHC UHS-I Memory Card includes an SD adapter and use that on my TF700 without any issues at all.
I have connected it both directly in the SD slot and also via the adaptor via the OTG dongle into the USB slot as a 2nd memory card.
Both have worked reall well, so am surprised the card is not working for some.

I just got my SanDisk Ultra 64GB microSDXC Class 10 UHS-1 from amazon today, worked out of the package and then reformated to exFAT and worked also. Haven't do much else with it but so far so good.

For an SD card I picked up a Polaroid 64GB SDXC Class 10 UHS-1 for $32 a couple weeks ago (was going to get a SanDisk as well but for $20 off figured I'd give it a shot and it had some nice write/read speeds), worked out of the box on my dock and did the formats. Rght now I've got it filled up with 60gb of movies for an upcoming trip and everything seems to be working fine as well.

Did you try that Polaroid card in the dock only or does it both work in the dock and the tablet. I might just buy 2 of these and be done with it.

Sorry, the Polaroid is an SD only. I picked up the SanDisk for the microSD. I didn't find a Polaroid option with 64gb for the micro.

Is 16gb enough for apps to sd?

I am currently using 64G Samsung in my TF700t. It works perfectly fine with the original format extFAT. I reformated it with FAT32 and Ext4 for Data2SD. I don't have any problem so far.

I got the Samsung UHS-1 from Amazon as well, tested it and I am very happy with this investment of $65. Now when I do a TWRP backup, it finishes in 212 seconds for 1850 MB, averaging 8.7MB per second. When I copy files over from a PC, using the Silicon Power USB 3.0 card reader which is UHS-1 compatible, I constant have a write speed of 14.5 MB/s and the Read speed is over 27 MB/s.
They advertise to have a read speed of 70 and write speed of 20 though.
Your pc probably just cant go any faster .
I'm using two 64gb SanDisk SDXC class 10 in NTFS format, and two Medion (aldi) 32 gb class 6 in NTFS.
All four work perfectly well. But they are only used for storing media.

I use SanDisk Mobile Ultra 32GB UHS card as my Data2SD card. Formatted with FAT32 and ext2. NTFS works fine too. But be aware that ext 4 with Data2SD on this card might cause some trouble. I had a lot of freezes and random reboots with Data2SD as long as I used ext4 format. Now I formatted to ext2 and so far I had no freezes nor reboots.
Comp Addable!

[Q] 64GB MicroSD Class 10 slower than 32GB Class 10?

Hey all,
i bought a 64GB MicroSDXC Class 10 / UHS 1 for use in my HTC Sensation XE. It came formatted with exFAT which isnt an option on the Sensation so i reformatted the card to FAT32 (allocation unit size 32KB, was the default setting in the tool i used). Now, when i transfer files while accessing the card via card reader in my computer, the write speed is somewhere between 9 and 10 mb/s, which is fine. When i use the card in my phone though, the write speed for large files is only about 5 mb/s. The really odd thing: for the last months i've been using a 32GB card that also has class 10, and it gave me those 9-10mb/s while using it in the phone, too. Which means the bigger card is considerably slower than the old one, although the speed class is the same, and they both work at they same speed when plugged in in the card reader. Why is the new card working so much slower in my phone?

Will this SD Card work?

In the SGT 2 10.1?
Thanks
can't see any reason it wouldn't, after all it's just a 32GB card.
Should be an SDHC card at that size, not sure why the article talks about SDXC as you get further down, but even if they failed to follow the STANDARDS and made a 32GB SDXC card all you would need to do is format it to fat32 in a PC (using a drive formatting program as windows won't go that high on fat32 partitions) and you'll be golden. I'm using a 64GB in my 7" thats from the same model line.

Does Xperia M2 Support 64gb micro sd card?

Does our smartphone support that capacity? I need more for long hd video
Thank in advance
Well they recommend 32GB I've not tested it with 64 gigs
-removed-
I can personally confirm the Xperia M2 does support Micro SDXC UHS-I cards, tecnically of up to 128GB, but I'm not too sure about that.
In my case, my Samsung MicroSDXC Professional of 64GB works quite well for 1080p recordings, almost no wait time. Write Speed of something less than 40MB/s, Read Speed of up to 50MB/s, limited by our phone's Micro SD adapter, as in my PC via USB 3.0 adapters I get up to 90MB/s of Read and 80MB/s of write.
The card is standard formated in NTFS i think...
1. Format your 64GB SDXC to FAT32 on your pc.
2. Then insert it and your Xperia will detect your sdcard.
I used this card in my M2 Aqua: SAMSUNG 64GB MICRO SD EVO UHS-I CLASS 10 48MB/S (formated to fat32)
