RE: RAID recommendations?

["Paul Gordon" <paul@xxxxxxxxxxxxxxxxxxxxx>]

Ah yes, - good spot...

I definitely *do* want the online expansion ability, - since I know I'm
not going to be able to afford that many 400GB drives all in one go, so
I definitely plan to start of with probably 4x400's in RAID 5 (1.2TB
volume), and then add more 400GB drives over time as/when required.

Since I reckon I'm going to be OK until about Christmas, I may put off
buying until then, since I'll have more spare cash by then, plus I
expect the prices will have dropped a little more by then too...

I'm also tempted to hold out for a PCIe version - since I don't reckon
there's much future in the PCI-X bus now that PCIe is here...
