I am thinking of adding my old drive (Seagate 3.2G 5400rpm) to my new
PC which include a Samsung SATA150 80G 7200rpm, but I am having second
thoughts:

1) I am concerned about the mismatch of performances between the two
drives; after a quick test the Samsung registered about 65MB/s
(read/write) while the old Seagate only recorded a mere 7.3MB/s.
Should I bother the hassle of installing the 'limping' Seagate
alongside the Samsung in order to "improve" overall audio recording
performance?

2) The initial idea was to use the Seagate as a "tape reel" and the
faster drive for the operating system. It seems that there are
conflicting suggestions about this subject...in fact many in this
forum suggest exactly the opposite (faster drive for audio).

3) I've also read that the pagefile is better be confined away from
the OS drive...
I was thinking of doing a small Pagefile partition (512Mb) on the old
Seagate and dedicate the rest for audio recording only. Will the
pagefile partition sited alongide the audio partition compromise the
performance?

4) I am contemplating to implement a SATA Raid system (and ditch the
old Seagate altogether) by adding an extra drive (another Samsung) for
a Raid(0) setup.
My motherboard (a Gigabyte GA-K8VT800pro) has an onboard SATA Raid
controller (and also an IDE Raid controller).
As the 2 Samsung will help each other in improving read/write
performance it seems that they are acting as a single unit therefore a
third drive would be ideal to separate the audio recording from the
OS?
Raid setups are still a new thing to me and any suggestion is
welcomed.

Thanks,

Alex
