[Q] Error writing buffer. - Galaxy S 4 Q&A, Help & Troubleshooting

Hi guys.
When I'm trying to check my read/write speeds, SD Tools gives me information about error writing buffer.
I own S4 i9505 16GB version with external 8 GB memory card.
I have changed cache size for both to 1024 kb using SD Booster
I can easily take pictures, copy things and do other stuff without any problem with memory cards.
AnTuTu Benchmark couldn't go over testing i/o performance.
What could be the problem?

4 gb sd card optimization

hi all;
I get a 4 gb sd card for my jamin, but I am not sure how could I get the best performance from this card? for now it does not seem faster thatn my 512 MB Kingston SD card so which cluster size and format settings should I use
Use the utillity Pocket Mechanic, it going to help you to perdormance your SD. The last version is 1.60 or the Pro version is 2.10.

[Q]What are you transfer rate speeds WRITE/READ on default SD card?

Last night i received an error stating my SD needed to be reformatted after playing around with a couple of ROMS.
After a fresh format i get around 2.67 - 3.00 MB/s writing a 1gig video file to the default 16 gig SD card.
Does that sound about right?
I am just wondering if perhaps i formated my SD card the wrong way or what is the best way to format it for use with the EPIC?
More than likely it's a class 2

[Q] NAND too slow when enabled A2SD+ partition

can someone please help me?
I have tried many builds and they are all unusable for me when they are using SD partition.
Disabling it makes it usable again but no user space!
I have tried CW method of partitionig and GParted but always same result
My SD is Class 2, don't know if that is problem... tried many times to format it... tried many NAND ROMs.
Please help!!!
Brand, size of your sd card?
What format? Windows?
File system used in ext partition of sdcard?
Try a HDD benchmark test on your SD card. If sustained write is less than 2mb/s, then you want to use SD Card Formatter 3 with ERASE FULL (ON) and RESIZE (ON), if still slow, time to buy a proper sd card.
i noticed it by myself. got a 16 GB class 2 SDcard and since NAND-roms its really messy, changing the screens by sliding (stuttering - and gets worse the more apps are on it), loading apps are much slower than with SD-roms.
i ordered a 8 GB class 6 SDcard last friday, hope to get it tomorrow. will check it out with a fresh format and install asap. will come back and post my experience.
It's Kingston Class2 16gb.
First partition is FAT32 15gb, and second is 1gb EXT3 (also tried with EXT2 & EXT4).
It's strange but I remember that SD builds were much generaly faster (thats not the case when I turn off this partition).
Here are results:
Read 10.130 MB/s
Write 2.163 MB/s
I think they are good for Class2.
Any opinion is welcome!
Eww.. Kingston MicroSD.
You're right, their speed scores are pretty good. Stuttering is usually caused by slow reads, writes don't cause stuttering, except mainly when installing apps. Your card isn't corrupted, because the speeds are exactly on spec.
Well, the first few days of using ext partition on SD card for A2SD+ is going to be slow, till everything is written on the SD card, then it speeds up considerably. I recommend, try using it for 2 days, and see if you can't stand it.
SD builds already have everything in the SD card, including data.img where userdata is stored. However, with A2SD+, everything is in the NAND, but the application will move to SD Card ext3 partition, at the same time the Dalvik is also being moved there too. So yah, it can be slow, until everything is done scooting over.

mem speed

Hi,
I'm using a Wildfire with CyanogenMod v7.1.0.1. When I changed to a 16G sd-card recently I began to think about the various app-to-sd methods and put an additional EXT partition on the card "just in case".
Just one question: How does my sd-card performance compare to internal flash speed? How can I find out? "SD-Tools" benches my card at 6 MB/s write, 25 MB/s read. What's the speed of the internal flash?
Regards
edit: second question reg. app2sd-method removed (found the right one for me myself in the meantime)
intenal flash faster than mem card i think so!
Try S2E app from market

[Q] Can I use NTFS on file system of my 32GB C10 Micro SD?

Hi there, guys!
I want to be able to save large files on my Micro SD, but I know that FAT32 has a limit of 4GB for the maximum file size. So, can I use NTFS when formatting my new Micro SD? Note 3 will read it normally?
Thanks in advance!
Guys, I just noticed that ExFat is also an option when formatting. Reading about that I found that it's possible to use files larger than 4GB.
Now the thing is... Everything will be just compatible as when using FAT32? In terms of reading and writing speed, and apps usage in general, it's the same thing?
