Comment 25 for bug 500069

sbec67:
Have you tried your device with another OS with different performance results?

From your lsusb output is does not look like your device is listed? Was it plugged in when you ran lsusb?

If that doesn't turn up anything obvious you should probably see https://help.ubuntu.com/community/DiskPerformance and test whether the raw device performance is better than when formatted. Backup your data on the device first.

dd numbers with bs=1M in addition to the bs=32 would also be interesting.
