The Intel X25-V 40G drive is the one I would recommend, I use it as a system drive in one box, it's not as fast (linear write speed) as the X25-M drives, but it's definitely a step up from the 5400rpm 2.5" drive I used in the system before :P Ah that sounds good for md bitmaps and filesystem journals on small-medium sized machines. But definitely going o/t now I'm also thinking of upgrading my laptop to an SSD, 4GB RAM and Windows 7 (sorry for swearing ;-) so that's probably a bit small and slow. Even the X25-M's 70MB/s quoted write speed sounds a bit slow (a minute to hibernate?) but are Intel still the only ones with sane firmware? (A look at Anandtech's storage pages suggest this area is a minefield.) So I was wondering what to get, whether getting anything with faster writes than Intel's current generation is risky? Cheers, John.
