Uruk Droid - SD card results thread - Gen8 Android Development
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!

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:
Manufacturer/brand name:
Card size:
Card class:
Card URL:
Filesystem type (/data partition):
Performance feelings:
Performance details:
Click to expand...
Click to collapse
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)

Perforce feeling: Ok - bit better than internal system on average, except Media Scan which takes FOREVER (may not be due to card - it has no media on it whatsoever)
I'll dig up numbers again specifically, but a previous test on the vfat partition rendered results in the mid 6MB/S ballpark if I remember correctly. Kingston is known for being a bit on the slow side of things.

Hmm, same card as cjdalessio but I don't really have the same issues as he does. Our metadata scores are completely different, similar throughput. What does the metadata score signify?

Like I said - score is just for you and it's not "real" benchmark result. I had to made some assumptions (that I've implemented in test - it still needs to be calibrated). While doing metadate test sometimes it runs too quick to be measured - that's why you can see in the last line of result some "+++++". I've substituted this "unmeasured" value with some number for score purpose - it's obviously to small. When you compare this line (with many coma separated number) they are almost identical.
And mediascanner - it's speed depends on how many small files you have and how your directory are "protected" with ".nomedia" lock.

So... mediascanner seems to start any time you touch the filesystem. I think these results may be tainted with that right now. Not sure but suspecting. Trying to get some data to back that up.

In Uruk 0.6 mediascanner can be disabled - and run on demand (we are testing it now and Solune is changing it's UrukConfig to back it up)
Excellent. Enough work today so I won't try it now but will try this weekend I think (expecting nasty snow the next couple days so may find time sooner.)

I must say that nimrodity test on internal gave me some thinking - i'll test it then since it looks quite promising.
I've change some calculation (so your's "scores" may be not the same as on graph) - but this changes have been also put to iobench.sh (this are mostly fixes since sometimes " " empty chars made calculation wrong).
I've added also in description "filesystem type" since I've assumed it's always ext4 - but some of you switch back to ext3 - so please update this information (i'm talking about filesystem of /data partition).
We need some "bad" sdcard results! So please if you have some cards that feels to work badly/terrible - please test it
Like for now I guess that metadata score/tests has bigger influence on system "smoothness" (and this is what I was able to tell without test anyway) - but we needs some proofs and measure of this - bad card needed

SD cards speeds?
I notice SD cards are rated 60x 133x or greater. Will I notice a difference on my Blue Angel? Is the BA USB interface version 2.0? I'm torn between getting the Sandisk 1GB (with built in USB) or the new 2GB, a third option is the new Sandisk Extremee III (1GB) with superfast 20Mbps xfer.
I am curious t this as well.
I recently purchased a no-frills 2GB SD card from newegg that claimed to be 150x. When benchmark testing with PocketMechanic, I saw that my storage card only did 1.8x read / 0.8x write. However, the onboard storage benchmarked to be 2.9x read / 4.2x write. [Note: Both onboard Storage and SD Storage card were formatted before testing.] I haven't done the research to find out if BA is USB 1.1 or 2.0, but I've noticed that a USB SD card reader is significantly faster than transfering files through the BA. It took 4 minutes to transfer 73MB for 193 files and 39 folders via windows explorer, or roughly 300K/s, where as I was able to transfer 1.5GB in 401 files and 59 folders in roughly the same time via USB SD card reader. If the speed of the no-name card is in question, I confirmed the speed to be at least 5.5MB/s, by copying back 1.5GB in 401 files / 59 folders in 270 seconds via USB to SD card reader. Had this been one single contiguous file, the transfer rates would have been alot faster... I could have confirmed by copying a like-sized file to the media, but you'll have to take my word on this, as I've already spent quite some time satisfying my own curiousity to answer your question See below for Pocket Mechanic details: Details: Card tested "Storage Card" Min. read time: 0.25ms Max read time: 18.00 ms Avg. read time 1.87ms Sector/block: variable 4-64 Min write time: 0.50ms Max write time: 16.00 ms Avg. write time: 4.02ms Read/write ratio: 0.46 Sector size: 512 bytes Start Sector: 0 End Sector: 3910656 Total Sectors read: 2504 Total data read: 1.00MB Total read time: 4673 ms Total sectors written: 2504 Total data written: 1.00MB Total write time: 10057ms Details: Card tested "Storage" Min. read time: 0.25ms Max read time: 16.00 ms Avg. read time 1.14ms Sector/block: variable 4-64 Min write time: 0.50ms Max write time: 9.25 ms Avg. write time: 0.80ms Read/write ratio: 1.43 Sector size: 512 bytes Start Sector: 0 End Sector: 125488 Total Sectors read: 2504 Total data read: 1.00MB Total read time: 2855 ms Total sectors written: 2504 Total data written: 1.00MB Total write time: 2001ms
Thanks, pity you ont have any other cards to compare too.
FYI, my curiousity got the best of me again, so I tested my no frill card's speed more thoroughly. According to SiSoft Sandra, my card is at least 55x to 65x at 64MB chunks, via USB reader. See below for full details. I also performed my own test, where I copied a single contiguous 1.9GB file (1944973970 bytes) to and from my SD card via USB reader. Read: 262.50 seconds, 7.4MB/sec, 40x (@ 176K/x) or 50x (@ 150K/x) Write: 204.84 seconds, 9.4MB/sec, 53x (@ 176K/x) or 63x (@ 150K/x) This is no where close to the 150X claimed speed, but this may be a limitation of my 2.33Ghz Centrino laptop's 5400RPM hdd? Really can't tell since I don't have another SD card to test with, nor do I have current plans to test on other hardware...

SD CARD - FAT16/32 - Cluster Size - Performace numbers
Just wanted to share some simple performance figures I pulled on my TyTn's Storage Card Device: TyTn (HERM200), ROM 3.54.253.3 OS: Windows Mobile 6, CE OS 5.2.1437 (Build 17944.0.3.1) Storage Card: 2 GB SanDisk ultra II Micro SD card Testing Tool: SKTools 3.1.9 Notes: -Before testing I used SKTools to optimize for performance. this changes cache setting and I imagine this has an effect on test results. -I have no idea how SKTools mesure performance, what mis of large/small files. -Each filesystem format was only tested once. I tried running it a couple of times for one of the formats, and noticed a small difference. -All results is without backup FAT, to get the fastest performance. -First two bars in the graph is FAT16, the rest FAT32 -The number after FAT16/FAT32 referes to the cluster size, ex. FAT32-16 has Cluster size set to 16384 -WRITE SPEED IS MULTIPLIED BY 10 TO MAKE IT FIT IN ONE GRAPH Graph Regards ThMoJe
Speed compare MicroSD Card class 6
Hi guys, I propose a topic to compare different speed of microSD Card : Software test : sktools benchmark Verbatim 2 Go : write : 380,63 kb/sec read : 13128,59 kb/sec Sandisk sdhc 8 Go ultra class 6 : write : 734,14 kb/sec read : 13356,52 kb/sec I disappointed of performance to sandisk class 6, the read speed is same of a Verbatim. I tested this Sandisk with a windows PC software (flash memory Toolkit), write : 13358 KB/s and read : 17356 KB/s. There is a big difference. The HTC cruise have a hardware limit ??? I would get the speed of Sandisk sdhc 8 Go class 4, thank you for your results.... new 02/04/2008 : the activeSync is faster with Explorer/StorageCard for copy/read files
http://www.comshop.si/Article.asp?articleid=57961 I have this card. Storage card write 551.77 KB/sec. Storage card read 1906.89 KB/sec. I allways have just Transcend cards. They are the best and you have lifetime warranty.
"Storage card read 1906.89 KB/sec." Your card is slow, it's strange...are you sure ?

what is difference between inner storage and sd card ?
are they both NAND Flash storage device? the only difference is that the inner one is fixed to the device and difficult to remove from device, while the sd cards are removable, any other differencees?
dalvikna said: are they both NAND Flash storage device? the only difference is that the inner one is fixed to the device and difficult to remove from device, while the sd cards are removable, any other differencees? Click to expand... Click to collapse yes both are nand device .......now a days flash nand technology is used in solid drives. NAND has so many advantages over NOR technology like higher densities, larger capacities, and lower cost. It has faster erases, sequential writes, and sequential reads. inner storage has more pins than sd cards . sd card have 8 pins where as internal storage have 16 or may be 32 pins which results into high read write speed . both sequential as well as random read write speed of inner storage are better than sd card . if you want to know more about random read write speed go to this thread : http://forum.xda-developers.com/showthread.php?t=2742903 i randomly performed a disk marking and got following results . test performed on 50 mb space 1. inner storage (device micromax canvs hd )' ----------------------------------------------------------------------- CrystalDiskMark 3.0.3 Shizuku Edition x64 (C) 2007-2013 hiyohiyo Crystal Dew World : http://crystalmark.info/ ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 34.813 MB/s Sequential Write : 6.757 MB/s Random Read 512KB : 34.773 MB/s Random Write 512KB : 2.992 MB/s Random Read 4KB (QD=1) : 13.044 MB/s [ 3184.6 IOPS] Random Write 4KB (QD=1) : 1.079 MB/s [ 263.3 IOPS] Random Read 4KB (QD=32) : 15.335 MB/s [ 3744.0 IOPS] Random Write 4KB (QD=32) : 1.143 MB/s [ 279.1 IOPS] Test : 50 MB [H: 37.1% (671.3/1809.3 MB)] (x1) Date : 2014/05/15 23:21:18 OS : Windows 7 Ultimate SP1 [6.1 Build 7601] (x64) 2. sony sd card (32 gb class 4) rystalDiskMark 3.0.3 Shizuku Edition x64 (C) 2007-2013 hiyohiyo Crystal Dew World : http://crystalmark.info/ ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 8.725 MB/s Sequential Write : 3.028 MB/s Random Read 512KB : 8.715 MB/s Random Write 512KB : 0.659 MB/s Random Read 4KB (QD=1) : 2.548 MB/s [ 622.2 IOPS] Random Write 4KB (QD=1) : 0.247 MB/s [ 60.4 IOPS] Random Read 4KB (QD=32) : 2.905 MB/s [ 709.2 IOPS] Random Write 4KB (QD=32) : 0.384 MB/s [ 93.7 IOPS] Test : 50 MB [E: 16.7% (4.8/28.9 GB)] (x1) Date : 2014/05/15 23:26:53 OS : Windows 7 Ultimate SP1 [6.1 Build 7601] (x64) 3. pen drive 16 gb hp CrystalDiskMark 3.0.3 Shizuku Edition x64 (C) 2007-2013 hiyohiyo Crystal Dew World : http://crystalmark.info/ ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 19.958 MB/s Sequential Write : 5.597 MB/s Random Read 512KB : 22.317 MB/s Random Write 512KB : 0.997 MB/s Random Read 4KB (QD=1) : 4.655 MB/s [ 1136.4 IOPS] Random Write 4KB (QD=1) : 0.012 MB/s [ 2.9 IOPS] Random Read 4KB (QD=32) : 5.362 MB/s [ 1309.2 IOPS] Random Write 4KB (QD=32) : 0.013 MB/s [ 3.1 IOPS] Test : 50 MB [D: 0.1% (0.0/15.0 GB)] (x1) Date : 2014/05/15 23:42:49 OS : Windows 7 Ultimate SP1 [6.1 Build 7601] (x64) now you can easily compare the basic difference . i found that random write speed is maximum in case of inner storage which is required for better performance of operating system (refer the link of thread ).
