amazon basics 4GB class10

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.

Results for a Samsung 32Gb SDHC Class10

by Santiago Castillo Oli

Hi flashbench-results. I'm trying to get the most from a Samsung 32Gb SDHC Class10 card. I've run a flashbench (compiled for x86) on a Asus Eee PC 901. I'm posting the results as an attached file to this message. I guess the page size is 16Kb, but not sure about erase block. What do you think? Strangely the 4 Mb boundary is faster than bigger boundaries.
