Intel’s best value on high-density Intel 3D NAND Up to 4.7x performance over SATA Up to 90 percent IOPs consistency Up to 100x more effective at preventing SDC Intel DC S3520 Series SSDSC2BB480G701 480GB 2.5 inch SATA3 Solid State Drive (MLC).

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.

The range of scores (95th – 5th percentile) for the Hitachi HTS543225A7A384 250GB is 29.9%. This is a relatively narrow range which indicates that the Hitachi HTS543225A7A384 250GB performs reasonably consistently under varying real world conditions.

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.
