Simple external RAID backup?

[Chet Nichols III]

Noticed no one ever responded to this.. but.. I agree that you should go
with software raid and use md. The only drawbacks I'd say for this are that
it's not SATA, and I'd question what this means:
>> Each drive shows independatly to the operating system with top transfer
speeds reaching 34Mps

Since it's USB 2.0 it should be nearing 60MB/sec, so not sure where they get
the 34Mps number from.. and, is it 34Mb or 34MB? I'm hoping they at least
mean 34MB.

Have you looked into the Buffalo LinkStation or TeraStation NAS products at
all?
