PNY 4GB microSD Class 4 C04G Taiwan manfid 0x000002 oemid 0x544d

by Andrew Bradford

If I'm reading my results correctly, this card is 2MB erase blocks and 8KB pages and it can only have 1 open segment at a time? It's not that fast of a card, I have another one with ext3 running on a PandaBoard with Emdebian Squeeze. As this is my first usage of flashbench, if there's any other info that would be useful, please let me know. This card was brand new before testing.

The blocksize argument actually doesn't really affect anything, except how many tests are run -- with blocksize=8192 it just stops earlier than with blocksize=1024. What I normally need is the result of one run with --nr-open-au just after the threshold, i.e 6 in this case.
