Transcend Ultimate 32GB Class 10 microSDHC TS32GUSDHC10

by Victor

Hi! I've started using that great tool to figure out how I should partition some cards but I'm not sure how to continue after the first results I've got and I'd like some guidance. Also I'd like to know if the card reader can influence the results since I've tested with 2 different laptops internal SD card readers and noticed differences in the times. I also checked with 'dd' the speeds and found the writing speed limited up to less than 10 MiB/s and a reading speed limited up to 14 MiB/s or so with chunks of 32 kiB and 4 MiB. Eventually I checked on an Android phone and got the writing speed limited up to 11 MiB/s or so and the reading speed limited up to less than 20 MiB/s. To make sure I compiled flashbench to run on the phone and also found different times than on the laptops. # # Product Page # http://www.transcend-info.com/products/Catlist.asp?LangNo=0&modno=320 # # Details # $ head /sys/block/mmcblk0/device/* 2>/dev/null | grep -v ^$ ==> /sys/block/mmcblk0/device/block <== ==> /sys/block/mmcblk0/device/cid <== 1b534d30303030301078944a9000c100 ==> /sys/block/mmcblk0/device/csd <== 400e00325b590000e9e57f800a404000 ==> /sys/block/mmcblk0/device/date <== 01/2012 ==> /sys/block/mmcblk0/device/driver <== ==> /sys/block/mmcblk0/device/erase_size <== 512 ==> /sys/block/mmcblk0/device/fwrev <== 0x0 ==> /sys/block/mmcblk0/device/hwrev <== 0x1 ==> /sys/block/mmcblk0/device/manfid <== 0x00001b ==> /sys/block/mmcblk0/device/name <== 00000 ==> /sys/block/mmcblk0/device/oemid <== 0x534d ## i.e. "SM" ==> /sys/block/mmcblk0/device/power <== ==> /sys/block/mmcblk0/device/preferred_erase_size <== 4194304 ==> /sys/block/mmcblk0/device/scr <== 02b5800200000000 ==> /sys/block/mmcblk0/device/serial <== 0x78944a90 ==> /sys/block/mmcblk0/device/subsystem <== ==> /sys/block/mmcblk0/device/type <== SD ==> /sys/block/mmcblk0/device/uevent <== DRIVER=mmcblk MMC_TYPE=SD MMC_NAME=00000 MODALIAS=mmc:block # # Size # $ cat /sys/block/mmcblk0/device/block/mmcblk0/size 61315072 # # Factor # $ factor 61315072 61315072: 2 2 2 2 2 2 2 2 2 2 2 7 7 13 47 Does it mean that the erase block size could be 7 MiB?

amazon basics 4GB class10

by Arnd Bergmann

Do not buy this card! This seems to be a Phison controller with identical behavior to the Toshiba ones used in Kingston cards. Essentially all cards that report "0x5048" ("PH" in ascii) or "0x544D" ("TM" in ascii) in /sys/block/mmcblk0/device/oemid are no good and should be avoided. These will be two orders of magnitude slower on random writes than a reasonable model.
