[Q] Internal SD reading and writing speed

Hi guys, I'm writing this post because I'd like to know if my writing and readind speed of the INTERNAL SD are normal for a stock rom or if there are some problems. I tested it with Antutu and my results are:
Writing Speed 5.6 MB/s
Reading Speed 8.7 MB/s
I actually have JVU rom with stock kernel, I dont'like custom roms and kernels and I prefer keeping the stock ones. I also tried JVS and JVT with same results. I'd like someone of you to post his benchmark with stock roms.
Thank you in advance.

Mine Samsung Galaxy S Plus completely stock Android 2.3.3 nothing changed from buying:
SD card write: (6.1MB/s)
SD card read: (22.4MB/s)

Thank you for your reply. There is an excessive difference, expecially in reading speed. Even if you have a different Galaxy S.

Your reading is a little bit slow?

Yes, it is. I'm worried about reading, not about writing.

Any other bench?

when I only tested sd:
write:6.5MB/s
read: 17.2MB/s
When I did a default test:
write:6.7MB/s
read: 20.6MB/s
Mine sgs is overclocked to 1200, but that shouldn't alter the score that mutch.
Maybe try another rom or go back where you bought it and sent it in for repair.

[Q] Does this phone support Micro SDXC cards?

Has anyone tried an SDXC card with the RAZR i? If so what filesystem and did it work?
Thanks.

Is this what you are looking for ?

Yes, has anyone tried one of these yet?

Yes. I'm running that one just fine (shows as 59.46GB). Just make sure you don't reformat it on your PC...

By definition, microSD is limited to 32 GB and only microSDXC can go further.
Spec sheet says Razr i can support 64 GB card, so I guess this should be okay.
Well, the same spec sheet says that there is no FM radio...

That's great news.
What is the file system? I'm interested to see if it supports exFAT.

I have not tried exFat because I had already formatted it in fat32 for use with a xperia ray...
So, I have this sandisk 64Go fat32 installed on my Razr i and no problem!

I'm pretty sure android doesn't support it. Exfat at least doesn't work in any of my Android devices

XXLS2 and exFAT support

Did sammy include the exFAT support in the new JB rom as it is available for S3
Becuase Large SDcard (64GB Sandisk) work best with this specific format
other formats needs alot of mods to work with laggy performance
I think it should has native support for it
older roms are not supporting exFAT due to licensing issues with microsoft
please everybody share your knowledge about this topic

I'm not running the JB rom yet, but 64Gb cards work fine on ICS 4.0.3 and 4.0.4.

your card would be Fat32 which does not support files>4gb size

ExFAT works on ls7.

Did u try it by adding files larger than 4gb ?

We need more tests, maybe must put on many films, musics and images.

This was pretty much obvious. 4xHD supports 64GB SDXCs, which were the largest available cards at the time. There's no software or hardware additions needed for a device to support a larger capacity once it supports any SDXC card. But thanks for the tip.
More pressing problem remains: 4X needs to get a universal driver for exFAT (not just thru Demetris' Optimus Play! kernel).

Only on Omni. This applies to exFAT formatted partitions only.

wait... as i can see in video it is working on stock rom... so i assume stock rom can use only FAT32 formatted cards but if i format it in FAT64-exFAT only omni will see it.. when i format it in fat32 stock and omni will work both with it but i cant use files larger than 4 gb, am i right?
or even i can partition card to 64 gb exfat and 64 fat32

I was also getting one

[Q] Swap external to internal?

is there anyway to do the swap on the Xperia Z C6602 any stock ROM (4.2.2, 4.3, 4.4.2)?
I had searched about it, and this is what I had Found, you need to modify the vold.fstab file, which should have 3 lines, for the internal, external and USB but mine have 2 there is no line for internal, and for the 4.4 can't be since this is related to the Kitkat SD restriction which can be fixed?
I have tried several ways, on 4.2.2 and 4.3 and even 4.4.2 with no success, so what is it I'm doing wrong?
My device is Xperia Z rooted and with dual recovery, Locked Bootloader, 64 GB Ultra sandisk, Stock ROM (4.2.2, 4.3, 4.4.2)

There is a thread discuss SD fix. you should search it more carefully.http://forum.xda-developers.com/xperia-z/general/fix-t2759826
you can use the method or an app.
I think 2G RAM is enough to run any apps so it doesn't need to swap.

thank you for your answer, but I'm not talking about the fix for SD writing since I know about it already,
I'm talking about making my 64 GB card act like my internal so I install more apps since we can't move apps, and the RAM has nothing to do with this, I hope now I'm clear.

Bro. That's app2sd, not swap.
swap means using part of your internal memory as device's RAM, it seems the Virtual Memory on Windows.
Stock 4.4.2 don't support it. If you have an unlocked bootloader, you can give a try on custom Rom.I'm on slimKAT 5.10 right now and it support this. butter smooth.

thanks, but even link2sd not working with me and the mount folder app too, so can it be done on any stock ROM? since the 16 GB is not enough for me apparently,
