Mike,

It seems these drives a derivatives of the devices optimised for the digital
video recorder market used in the security industry. I think this is where
the very high bitrate and "up to 16 streams" statements come from, recording
multiple, high resolution surveillance cameras simultaneously.

I have found a supplier in Aus that has the Seagate "SV35" drives, they are
about ~$20 more expensive than the "standard" drives.  I think I might get
one and see how it goes, shouldn't be any worse than a standard drive I
hope.

Cheers,

Roo.
