Having not bought a bare HD for many years (back in EIDE days), I did some research, and think that my choice will be between a Western Digital Scorpio Blue or a Western Digital Scorpio Black. (The Blue is 5400RPM/8MB cache, the Black is 7200RPM/16MB cache)
Both are described variously as having either a "SATA II" interface, or a "SATA-3GB", depending on the retailer, and the WD website says that the Blue is either "SATA 3 Gb/s" or
"SATA 1.5 Gb/s", whereas the Black is only "SATA 3 Gb/s".
I have read up a bit on SATA, and checked on the Lenovo and WD websites, but so far I haven't satisfied myself that either drive is compatible with the T500. Can anyone help me on this? Is either or both of these drives usable in my T500? Or do I need to go for a SATA 1 drive?
If both are usable, how should I decide which to go for? The WD website says that the Black uses no more power than a 5400RPM drive, but is this true? Naturally I'd prefer the faster speed of a 7200RPM drive, but it depends how much it would dent my battery life.
I would prefer if possible to use a WD drive, because I have had good experience with WD drives for nearly 20 years and disasters when I have used other brands, so pls don't try talking me out of Western Digital unless neither of these HDs is compatible.
I did read previous discussions on this forum, and I note the very good arguments in favour of SSD drives, but on this cheapo machine I can't justify the cost, so I'll stick with a spinning Winchester drive for now.
Thanks in advance for any help!
