The first thing you’ll notice is that the drive is rated to consume 10.70 wars during read and write, whereas during idle its rated to consume 8.20 watts. It should also be noted that despite Velociraptor comes with a massive heatsink, its 0.25kg lights compared to this drive on paper. The operating temperature is as same as what velociraptor has.
Like all hard drives, there is a foam sandwiched between the drive and the PCB.
WD uses Smooth’s L7251 3.1 ver. motor controller, Marvell’s 88i9045-TFJ2 controller and Hynix H5DU5162ETR-E3C 64MB DDR Chip for the drive’s Cache buffer.
I also wanted to note that throughout the time I have reviewed hard drives, Amphenol makes stronger HDD I/O connector in comparison with Foxconn’s alternative. Not that it matters to a lot of people, just something to point out.
