A lot of weird issues that popup while running Uruk Droid from the SD card may actually be the result of the card itself not being able to handle the constant read/write. Even if the card is labeled a class 10 you may get worse performance than the stock. I know, I used a class 10 for a week or two and it was essentially unusable, so I moved Uruk to the internal storage.

Use this thread to post your experiences and test speeds for the various SD cards. If you can, use $auron's method for some uniform baseline, but a general description of the experience is important because some of the issues don't seem to be captured by a speed test. Of course, please list the card's make and class as well as size.

Please use $auron's method in post 3 for testing.

I've created script with some io tests (based on bonnie++) - it should check both raw r/w and small files operations. It should be more precise that above script with dd (witch is of course also good - but can be not fully true if some sd cards prefer some specific block sizes)

Since UrukDroid 0.6 this script is installed by default. For older releases you can use this one:
File: UrukDroid-0.5-iobench.tbz2.
Save it with browser directly on Archos to /data/UrukUpdate (not over USB!).

How to run test?
To run the test, connect archos to power supply and run from shell
Code:
su
iobench.sh
Test run looks like this:
Code:
[[email protected] tst]# iobench.sh 
Turning on max CPU frequency: 1000000 hz
Performing disk (/data) IO test. Test make take about 1h on slower systems - please connect device to power supply!
Done: 0%...12%...20%...28%...36%...44%...52%...60%...68%...76%...84%...92%...100%

Restoring previous cpu setting....
What does tests do?
It creates files with different method (per char, per block, in sequential or random order) - this is throughput part.
Second tests check how fast we can create/access/remove files. More you can read about tool called bonnie++ on Internet.

So called score is just for you - it may be not precise, full precise data are in line below score.

How to report results?
I've tried to get as much data as I can from system level - but it does not give info about class level and brand name of SD card (witch can be different from manufacturer name). So this data must be added by user. My proposal is:
Quote:

Manufacturer/brand name:
Card size:
Card class:
Card URL:
Filesystem type (/data partition):
Performance feelings:
Performance details:

In performance details please cut/paste results from iobench.sh output - lines between ---- -----

How to buy cards?

Check graph from second post and try to get card that has possibly best metadata operation with throughput. Thumb rule is not to buy cards that has metadata operations below average - that is below red line.

Scores
I used the dd test and got the following scores:

Lexar 2GB, unclassified: 6,25MB/s
Adata 4GB, class6: 6,25MB/s
Sandisk 8GB, class 2: 6,66MB/s
Sandisk 8GB, class 4: 6,0MB/s (and dead now, so not available for future tests....

Not helping much I quess....

But maybe this helps:

I also tested under Windows with HD Speed from steelbytes, I found the standard block sizes of up to 8KB resulted in horrible, unstable performance. From 256KB up to 1MB performance became much more stable.

Well - after few tests made by people - we will see if overall filling is connected with some test results. Or we need to do other tests - like iozone (witch tries different portion of data sizes during write)
