You mean GBps, and that's because you're using system memory, not the flash NAND on the drive. I still see two potential issues with this:

1. Even with on-the-fly mirroring between ramdisk and flash drive, there's still going to be a delay between when you're finished with your work and when the drive has safely written all the data. Not much when you consider the fastest drives are hitting around 200MB/s writes... but there's no mention on the performance of the flash itself.

2. On-the-fly mirroring is going to wear down the flash fast. You'll probably hit other limitations before then, but it's something to think about.

Exactly. It's going to take time to flush the RAMDisk buffers out to the thumb drive. The read/write figures are a measure of the Supertalent software's ability to read/write system RAM, NOT the transfer rate between system RAM and thumb drive. A simple test would be to write a 4GB file to the thumb drive and detach the thumb drive (aww... let's be generous) 4 seconds after the busy prompt has gone. Then, try to read back the entire file on *another* PC. I reckon there'd be about 400MB to 700MB actually there.

You do realize that this drive will be capped at USB 3.0 max speed right? (400-450MB/s tops)

If only there was some way to get this kind of performance out of normal flash drives!:rolleyes:
