Thought this would be interesting to some of you:
Seagate Momentus XT 750GB Specs:
Interface: SATA 6Gb/s with NCQ
2.5" 9mm body
8GB SLC Flash
Capacity: 750GB (698.63GB Formatted)
Spindle Speed: 7200 RPM
I have one of the first generation 500GB XT (with 4GB Flash) running in my GFs 2008 MBP and it was a HUGE increase in performance when I put it in - for both OSX and Win7. Some of that performance increase could probably be explained from the increase from 5400rpm to 7200rpm, but it really was light night and day. Boot times are almost half my 2011 MBP, which I haven't switched to SSD because I needed the capacity.
Will be interesting to see how stable the drives turn out to be. It took about a year and 5 firmware updates before the last generation became acceptable. Mine has been perfect from day one, but mine already came with quite a late firmware and I read a lot of stories about instability with the early firmware.
