10 Cheap, fast & purty - pick any two.

12 What you're suggesting is at best a headache & more likely a complete
13 nightmare, just waiting to happen.

15 I can see that you have over 500GB of EIDE, so in the ideal world you
16 "should" be able to use that as the parity for your 2 x 500GB of SATA
17 drives.

19 But in the real world, spend £35.25 and get a 3rd 500GB SATA.
20
21 Use the EIDE for swap or non-redundant files or something.
22
23 Hard-drives from the "scrap" pile can be immensely useful, but if you
24 want ease of setup, reliability, redundancy and peace-of-mind then
25 scratch "cheap" off your list of requirements. Drives are cheap these
26 days, particularly 500GB ones right now.
