One of the frustrations of USB drives is the lack of performance benchmarks. To satisfy my own curiosity, I just did some 8gb flash memory benchmarks using aa1backup. These backups were back to back to back, always booting from the USB from a shutdown state. I was surprised by the results: Corsair Flash Voyager 29 minutes, 8.96mb/sec Patriot Razzo 14 minutes, 45 seconds, 17.96 mb/sec Transcend SDHC class 6 through SanDisk MicroMate card reader 18 minutes, 45 seconds, 14.04 mb/sec I expected performance differences, but not such a wide spread. I also tried booting from the SD card in the multi-card reader slot; no go. Note that these figures are for backup; it's quite possible that the figures would be very different for restore. Since I hope to do far more backups than restores, write speed is more important to me than read speed.
