We're looking at two new notebook hard drives today: Fujitsu’s 500GB 2.5" disk and WD’s brand new 640GB 2.5" model (the largest notebook drive you can buy). The capacities on both products are outstanding, but neither drive is completely perfect.
I bought the WD 500GB drive a few months ago now and am very pleased with it. I don't have benchmarks, but it feels a LOT faster than my older 60GB drive and extended my battery life a bunch. Running Win7 on top of that almost doubled my battery life under normal usage.
Yes I too am wondering if the 9.5mm 120GB/250GB 2.5" Toshiba hard drives that Sony ships inside the PS3 Slim can be replaced with a 12.5mm 2.5" drive. I don't have access to a PS3 Slim or a fat 12.5mm drive so I can't confirm myself.
Oh, that's why these HD makers have capacities as low a 80gb.. newsflash... flash memory is beginning to overlap these.. a redesign of the PS3/XBOX be made to use usb flash or sdhc flash instead of a HD at comparable prices!
I was about to comment that the numbers of hd's shipped in the 2.5" capcacities seemed like oversupply.. but when you factor in the low capacity hd's for consoles, it's about right. Still, anything below 250gb should be discontinued, IMO and come with 16mb cache memory (that's a big spread to have 80gb - 1000gb capacity in HD's when flash is beginning to overlap 64gb & 128gb usb sticks coming out and prices are bound to come down eventually).
