Adding drives to my Media Server

[Simon Ryley <simon.ryley@xxxxxxxxxx>]

The time has come when the little 80Gb hard disc in my media server
isn't big enough to store all the pictures, mp3s and freeview recordings
we now have.  So I'm looking to upgrade..

Current spec is a Spinpoint SATA 80Gb, holding windows xp, a few gig of
photos, 10g of mp3s and the rest as freeview recordings.

For performance reasons, I'd like to put the recordings on a separate
drive, probably a 250Gb Spinpoint SATA.  This leaves me with an 80Gb
drive that will be barely used.  Is there any way in windows or
otherwise to combine the two drives to one big virtual drive, giving me
about 60Gb of extra recording space, and hopefully improving the data
throughput as I am using both Sata channels in parallel?  The
motherboard does support Raid, but I've not been down that route before.

Is this a sensible option, and if not, does anyone have a small
Spinpoint sata drive they no longer want?

Cheers,

Simon
