Windows 7 - Another SSD or Raid Mechanical

So I have to RMA my Vertex, & Im back to mechanical drives for the moment.

Since it will probably be a week or 2 before i get it (or a new one) back, I had the idea of just picking up another.

Cash is a bit tight ATM, but I want some new goodies to put in my box so .....


--I have the option of getting another 30GB vertex SSD, just like the one I am RMAing.

With this option i can re-install onto the New SSD in 3 days, and when the new one returns from RMA, I have the option of a RAID0 array in a week or 2.
or just a second SSD for other things.



--Also noticed this: Newegg.com - Intel X25-V SSDSA2MP040G2R5 2.5" 40GB SATA II MLC Internal Solid State Drive (SSD) - SSD for the same price.

The Intel is 10GB bigger, but also has some horrible writes it seems.
The 80GB version is much faster, and looks similar in spec to the 30GB Vertex, but it is out of my price range at this time.

Anyone know anything about this Drive? Im unsure if the 40Gb version is worth it over the Vertex.

So the idea was maybe use the Intel as OS drive, and when I get the Vertex back, Maybe use it for Documents, Temp Files, Page File etc... maybe extra programs and a game that accesses HD alot for example. or vise versa.



--Then I have the 3rd option. Pick up a couple 500GB WD Blue Drives and run them in RAID0 for my games etc ... and just wait for the Vertex to come back from RMA for the OS.


Thoughts & opinions please.
