Hi Jim
Assuming this is on a TS72xx then you are probably going to have throughput
problems. The USB interface is only 1.1 We have tried this for a server app
and it was taking many seconds for the pages to load, even off rotating
media!
Yes you can do software raid on usb drives, again v2.0 is a lot better, even
then initialising the raid took a long time. We have done this using
rotating media, on flash drives I think the throughput would kill it.
Our experience shows that flash drives are significantly slower than rotating
media, which is hardly suprising when you consider that usb flash drives are
actually nand flash.
Just my 2 cents worth
