With 7mm ultra-thin hard drives all the rage, Hitachi aims to blast one out of the park with its new 500GB single-platter Z5K500 – that’s right, 500GB on a single platter. Getting to this higher capacity in such a slim package has been a big deal for drive manufactures, since in the 7mm drive space you are limited to a single drive platter, instead of two in a 9.5mm drive or three in a 12.5mm drive. While capacity might be the biggest selling point of this drive, it is also important to see how well it does in the performance category.

The Western Digital 500GB Scorpio Blue 2.5″ Internal Hard Drive is designed for use in portable computing solutions, and features a 3 Gbps SATA interface, 5400 RPM rotational speed, and 8 MB buffer size. It can transfer data at speeds up to 3 Gbps (buffer to host) and 136 MB/s (host to drive). In addition, the hard drive offers 5.5 ms average latency and 4 sec average ready time.

WD Scorpio Black 7200 RPM SATA 2.5-inch hard drives combine 7200 RPM spin speed, SATA 3 Gb/s interface, and 16 MB cache to deliver maximum performance for notebook computing.Confidence in knowing that all WD Scorpio Black drives are built to the highest standards of quality and reliability.

Quiet – In a notebook drive, silence is golden. WD’s exclusive WhisperDrive™ combines state-of-the-art seeking algorithms to yield one of the quietest 2.5-inch hard drives on the market. These algorithms also optimize the way a drive seeks for data, which significantly improves power consumption. So now silence (and longer battery life) is golden.
Reliable and Rugged – WD’s ShockGuard™ technology protects the drive mechanics and platter surfaces from shocks. WD’s SecurePark ™ parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved non-operational shock tolerance.
