Hi,
I recently bought a Lexar 633x 128GB SD Card that is rated at 95Mbps. Formatted with Android exFAT, the card shows only 20Mbps in Android but in Windows, the same partitioned card shows 96Mbps. I therefore suspect that the problem lies in the cellphone' software or its compatibility with exFAT extension. I have no option to format other than exFAT with Android. I have tried ext4 with TWRP but Android will not detect or mount it even with the mount command.
Any ideas on how I can get the right speed out of the card?
p.s: I am running the latest 2.19.40.22 firmware for ZE551ML
Have you tried formatting to fat32? You'll need to download a program separately to do that on windows
Hello,
FAT32 does not support filesystems larger than 32GB from what I have read. Windows only gives me the exFAT option. Is there a modded tool to bypass this limit?
Is ext4 faster for large files sequetial read?
thanks
EDIT: I found the utility and it works ok under windows but it freezes the cellphone after I insert the card.
@aziz07 hmm, what software did you use to format it? I used this. http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm I always felt fat32 was more stable on my Android device. It doesn't freeze my phone though my sd is 64gb
EDIT: actually, I just did some benchmarks and it looks like it does only read around 20mbps, regardless of the SD I use.
What are you using to test speed? I have a 64gb Evi and sometimes music stutters a but over Bluetooth. Not sure if it's a slow card, a problem with power amp, or just something that happens with Bluetooth audio occasionally

Just a random SD card benchmark app lol (a1 SD card), I would say that is more likely to be a problem with Bluetooth because you don't need high speeds for audio playback.
Yes, I used the same format utility but my card is 128gb. I will try again. May I ask what allocation unit size did you use and what is the fastest one?
thanks
Edit: I used the default allocation size and it worked. Its because I changed it to highest value before. I don't know if A1 app ratings are real for read but it shows 201mbps read and 47mbps write. I manually copied a 800mb file and speed was 48-62mbps write. For sure, its caching in RAM somehow to achieve 201mbps read. I guess the 20mbps was surpassed as I was getting ~12mbps write before. Worked A+
Try reformating the card. Whats the make of the sd card?
I had kernel mods applied long time ago though. ZRAM at 1Gb, noop scheduler with 2048Kb read ahead.
I like FAT32 because its the most compatible and the fastest for flash memory from benchmarks.
You guys using the 128gb card show all ur space on phone? Asus was telling me it will only show 64gb.

Same here. Yes, eventhough its advertised as 64gb sd card limit, 128gb cards work perfectly. The thing with FAT32 is the 4Gb file limit, many HD movies or high bandwith video shootings will require >4Gb files. I am still not able to mount ext4 formatted sdcards though. TWRP would recognize but not Android ...

Sorry I completely forgot to check back on this thread. I'm glad to hear its working better with the default allocation size, I think I probably changed it to the highest as well because after formating with the default size as well its working great .

Got my Note II. Everything is fine except the screen is too small. I seriously wish was 6 inch.
Anyways, the media player allows me to directly play .mkv movies. But I can not copy movie files onto the microSD that are largerthan 4 GB. Is there a way to overcome it?

Format your card with exFAT & you should be good to go. If you go that route, make sure you are using CWM since TWRP doesn't support exFAT SDCards.

What does CWM and TWRP stand for?
How do you install CWM on the Galaxy Note 2? Is there a link for this?
cwm is clock work mod. it is a replacement bootloader like the bios on your computer. it requires you to root. i cant remember what twrp stands for but its a competing bootloader.
TWRP= Team Win Recovery Project
Anyone knows a good, reliable software that formats to exFAT? Or does windows offer the option on it's own when trying to format? Still haven't received my micro sd, but I want to be ready for when it arrives.
Also, are there any cons to using exFAT, besides TWRP not supporting it?
the phone itself should do exfat samsung licenses the patent for it from microsoft. the stock format is fat32.

FAT32 is the limitation that will not allow >4GB file size. That is not a problem on exFAT or NTFS, but I'm not sure SGN2 reads either standard.

Can you confirm that SGN2 can read exFAT? It will not present an option to format it that standard. I get FAT32 on my 32GB microSD when formatting on the phone.
<EDIT> I really don't need movie files that large on my phone, I handbrake then down to acceptable sizes <4GB.

I doubt that. Internal storage is not like cpu freq, where you can increase it and see whether it is safe or not. This is like " I want to increase my pendrive storage from 1Gb to 2Gb without purchasing new pendrive."
Can it be done? By "hardware hacking" point of view, it is possible.
Should you do it? I guess not.

I saw a very lengthy and complicated way to use an sdcard as the primary storage (involving scripts, etc). So here's my quick question. I have rooted my device and want t know, is there an app or something very simple I can follow so I can start installing apps onto my 64GB sdcard? Right now it's just a piece of plastic with nothing on it.
Any help would be appreciated!
I am using this app it works perfect with Samsung 64gb uhs1 sd just change dev access 179:17 https://play.google.com/store/apps/...251bGwsMSwxLDIxMiwiZXUuY29kbGFiLmludDJleHQiXQ..
Quick questions
Thank you for the reply, I have figured it out now
Interesting - let us know if it's got any gotchas, but it looks like it may do a lot of what the scripts I put together did.
Only gotcha is...

The only "gotcha" that this program has is as follows: If you reboot your device or power it off, you have to reapply the "fix". It doesn't know how to modify the boot rom or whatever it's called to reapply the patch. No big deal since it's literally just two clicks. One to open the app, the other click to "Apply fix".
Hope this helps someone
For me, that'd be a big gotcha - I reboot mine all the time
I took a run at setting it up and I actually found it harder to be sure of what I was doing than when I wrote the scripts but that's really just down to taste.
One thing I saw in the writeup: if you do enable init.d (scripts that run at boot time) this app can create a script which does its magic at startup.
I have a sneaking suspicion that boot scripts are going to be available to everyone pretty soon.
Use SD Card as internal memory or RAM
You can use your SD Card as an internal memory storage space by using "Link2SD" app. There is another app known as "Swapper" (Swapper2 is the latest version), by using which you can use a segment of your SD Card as your RAM.
In both the cases you actually dedicate a portion of your SD Card to use as internal memory or RAM (whatever you desire).
NOTE: In both the cases, i.e for RAM and internal memory, you first have to repartition your SD Card and for that i must recommend you to use "MiniTool Partition Wizard" app.
For more info simply ask me
Thanks for the information. MPW needs the card out of the Note I found out. Makes sense.
Minitool Partition Wizard doesn't see my Note. What am I missing?
Windows 7 64bit, GT-N5110
Thanks everyone for your contributions,
using the external microSD as RAM and/or internal storage sounds great, but.... how does it perform in real life?
I mean we all know that swapping RAM and HDD in a desktop PC isn't gonna speed up things, right?
And although it's an sd card and not an HDD it is none the less a lot slower than the built in memory I would guess.
Does somebody have solid knowledge about it? Is there an impact on app loading speeds and background OS operations?
Thank you very much in advance,

hi! i am currently using a 64gb sandisk micro sd as my external memory. can i ask if this app works with the note 8: https://play.google.com/store/apps/details?id=eu.codlab.int2ext#?t=W251bGwsMSwxLDIxMiwiZXUuY29kbGFiLmludDJleHQiXQ

Good sir.... that ist the app we are discussing since post #2

thanks! i'll try..i'll post again if i have any more questions!
Having been told by samsung customer services not to expect a larger memory device for a while, I'm jumping on this thread to explore my other options as I really had my heart set on the 32GB model. I had limited success when trying this with my ASUS Transformer but I didnt try very hard to make it work to be fair...
Once you have an app like link2sd up and running is there any limitation to what apps you can use it for? My plan is to use it with large games that would otherwise fill up the internal memory.
Are there any performance issues with doing this with large apps due to lower read and write times on a micro SD card vs the internal SD?
Are there any issues if you remove the external SD card when not running those apps (id like to review photos from my camera on my tablet while I am out and about)?
If the answer to these questions are all no, I'll likely order the 16GB tablet ASAP.
Just found this thread.
http://forum.xda-developers.com/showthread.php?t=2285221
Think I will go for FolderMount if I can confirm there are no issues using it with a rooted Note 8.0. Im not fussed about moving the APK files. I'm sure there will be enough room on the internal SD for those. I'll just move the data files.
I dont think there would be any benifit of using a partition of the SD card as SWAP (unless someone can correct me on this). It already has 2 GB and the SWAP will be slow due to the max read write speed of the microSD.
If all goes well I will be picking my tablet up on Sunday ready to start playing

Should probably use exfat, SDXC has some issues in fat32 like loss of data.

Just put it in any Windows machine, right-click -> Format in Explorer, and choose exFAT instead of FAT32 or whatever.
With that said, I've had absolutely no problem using 64GB microSD cards with FAT32. There's one in my phone right now, and another in my tablet. FAT32 is an old (~1995) and simple format, and it's got limitations (no single file can be bigger than 4GB, for example), but it works and the support for it is extremely broad. ExFAT is a new version, and while all SDXC devices are supposed to support it, in practice I'm not sure how true that is. It shouldn't really matter either way, though.
Heck, if you want to, you could format the card with NTFS. You lose a bit of space due to the extra metadata, but you can the ability to encrypt individual files on the card, set access controls (the "Security" tab of file/folder properties), create symbolic links and junctions, store really huge files, and (possibly most important) you also gain journaling so that if the card is disconnected or loses power during a write, the file system doesn't get corrupted. Not saying you *should* use NTFS, just that you could...
I have not seen much information on having your nandroid seamless with the GS4 and able to also use the XFat system too.
What's with XFat? you might ask.... It's the fastest read/write system yet that is available to us GS4 users...
My backups used to take like 45-50 minutes, now it's a tad over 18. Recoveries are as well much quicker. Copying data ie. movie files, or the like, to the external SDCard is a whole lot faster! XFat gets the Class 10 SDCards performing at it's rated speed. Not to mention movies have better playback definition as well.
How do you get this performance gain?
I re-formatted the External SDCard using XFat. I was using FAT32 before due to the inability to use CWM on the XFat format, but I found out that this version (and probably other flavors as well) now supports XFat.... and so does even the Stock Sammy ROM does.... (proves that the hardware is well capable of it.)
Go here, and if you're using anything that is capable of read/writing to an XFat format, get the file!

You can get either:
philz_touch_6.15.4-jfltetmo.tar.md5
or
philz_touch_6.15.4-jfltetmo.zip
of course the "Zip" version is cwm installable right from your recovery, and the md5 one is easily flashed using Odin.(PDA)
I am impressed with this version, as it's very customizable.... Screen colors, menu colors, screen dimming, etc. and so far, I have had nary a problem using it. I like the fact that it will reboot the device after the completion of a backup or recovery, so I really don't have to "babysit" it's operation....
Sorta like a Ronco TV Informmercial product.... "Set it, and..... Forget it" LOL
Anyway, I just thought I'd share the information that has put a whole lot of spunk back into my aging GS4!
Good Luck and Aloha!

In theory, yes. However those specific cards have been known to fail. Not because of formatting, but just in general. There is a specific set of serial numbers that were defective. You'll have to search to see what the range of serial numbers is.
As for backups taking 40-50 minutes...that's the recovery more than the format of the card. Philz is just known to take forever. For all it's benefits, speed isn't among them.
Twrp takes about 5-6 minutes for a Touchwiz backup, 2-3 for an AOSP backup. Doesn't matter what the format of the card is. But TWRP isn't as fancy and customizable as Philz. So it's a tradeoff.
Ill keep that In mjnd thanks
