Fujitsu MJA2500BH
Fujitsu’s first 500 GB hard drive was the MHZ25000BT, which was based on three platters and a 12.5 mm height. Unfortunately, it was a 4,200 RPM drive, leading to insufficient performance for upper-class notebook systems; as a result, the MHZ2 BT was primarily offered to OEMs, which wanted these drives for media center PCs or similar solutions. The new MJA2 BH series also reaches 500 GB, but at a quicker 5,400 RPM spindle speed and using only two platters. This results in idle and peak power consumption that are slightly higher than the three-platter drive, but more power-efficient reads and writes.
The drive has 8 MB cache and a second-gen 3 Gb/s interface with NCQ support. We measured a maximum read throughput of over 82 MB/s on our new storage test system, which is a great result, as most of the 500 GB notebook drives deliver a similar maximum.
Write throughput is slightly behind Hitachi, WD and Seagate, but the difference is minor. The 18.4 ms access time is fast enough for typical applications and very much an average result for 5,400 RPM 2,5” drives; the only benchmark that the Fujitsu drive was unable to dominate was our IOMeter testing. The Fujitsu drive is strong in almost all sections of the PCMark Vantage HDD test, it delivered the lowest low power idle requirement of 0.7 W, and also featured nice, low power requirements for streaming, I/O activity and video playback.
Fujitsu makes the drive available at 500, 400, 320, and 250 GB capacity points. You can find more information on the Fujitsu Web site.

Give me a 2.5" Raptor and to hell with the battery!
2.5" Raptor drives are 15mm in depth and therefore are not suitable for notebooks which require 9.5mm or 12.5mm depth drives.
plus the raptors require active cooling and would soon suffer heat related faliure in the cramped confines of a laptop
plus the connections wont be the same as a normal 2,5" hdd.
You guys are telling me we can cram Core i7, 3 x mechanical hard disks, beefy GPU, yet we can't accomodate a Veloci Raptor?
I'm betting it could be done. Simple potential-divider network to get the +12v etc. But even underneath my M570RU, it seems like there is loads of space for something bigger, I can only imagine bigger notebooks might have even more, and if not, with a small case modification, who knows what might be possible?
I even considered taking on this project myself, but then, I just purchased an Intel X25-M 160GB, and as you know - that dropped straight in...
And the connections would be the same, 'cept for the missing 12v.
