Best performing/value SSD or duo, at 40-100GB?

Thanks for offering your thoughts AceNZ.

Max sustained read or write on a WD Black 1TB is 113 MB/s.

Max seq read on the X25-V is 170 MB/s, and max write is 35 MB/s. So a pair of them in R0 could be almost three times as fast as the HD in read, but only about 60% in multi-threaded or large block writes.

Actually I'm wanting to compare a SSDNow V G2 64GB, & OCZ Vertex (or Adata) 30 or 60GB*, to the Black & F3.
The X25-V's are being considered for my OS/boot volume, not my scratch-disk.

Most disk access patterns are heavily read-weighted, and more random than sequential -- so unless you're doing something particularly write-heavy, you should be better off with the SSDs than the HD.

No this is for a scratch-disk (I outlined my workflow earlier), not an OS/boot volume.
I'm considering a 2nd X25V for my OS/boot volume.

It can improve sequential too; the maximum sequential data rate is higher toward the outside edge of the drive. Here's a graph I did that shows typical HD sequential performance as a function of position:

Ah thanks for confirming...
I wonder what sort of sustained/seq performance boost I'd be getting if I short-stroked it to 500GB?
Judging by that graph it'd be approx. 70MBps...

*Or any other SSD with high seq/sus. R+W & lowest $/GB (don't need much more than 60GB total capacity)
