That's cromulent news!
title says it all
Western Digital has increased its fast notebook drive's capacity by half to reach 750GB, the same as Seagate's fast notebook drive. WD's Scorpio Black 2.5-inch drive spins at 7,200rpm and has a 16MB cache and 3Gbit/s SATA interface. It is now also an Advanced Format Drive. Seagate's equivalent Momentus 7200 had its 750 gig …
The WD Black range is known for being noisy and power hungry, so not all that great if you're going to be spending time on the move, but if you tend to use mains power at remote locations then brilliant (seems to be a popular popular choice for portable CAD workstations though)
They get them reliable. The last WD Black 2.5 drive I bought lasted about 6 weeks and had to be RMA'd. At least with the Bblack series drives they don't replace dead ones with 'refurbished' drives.
For now Samsung has proven to be the most reliable drives for me. I'll wait a few years to see if Seagate redeems themselves from the crap they've been slinging the last few years.
