In this the weakest link would appear to be the SD Card. As such it seems to me that the
best solution would be to have 2 or more SCSI2SD?s in the device. I?m not sure what
benefit would be achieved by using a single board to present multiple devices. Unless of
course you had a drive size limitation, or you?re trying to emulate something like 2GB or
4GB drives. As an example, that would be handy for VAXen with a 1GB Boot Drive
limitation.

I am wondering if anyone has used these to
replace HDDs in RAID
configurations? My thought would be it should work fine as long as they
look like real HDD to the system but who knows?
Looking at the FAQ it looks like it does:
"Does SCSI2SD do ECC or mirroring ?
No. However, you can configure SCSI2SD as up to four devices and use whatever RAID, data
duplication, striping, or mirroring capabilities your equipment supports."
In fact it looks like you can subdivide one card into four virtual drives and do
mirroring and RAID on one card. Kind of defeats the purpose but I guess it can be a cheap
solution to avoid having to buy multiple boards.
Now if they would make an UW version....
