Thanks to advances in manufacturing and 4 KB sectors, we finally have 2.5" hard drives with 500 GB per platter and a notebook-friendly 9.5 mm Z-height. Thanks to their high data density, even power-friendly 5400 RPM drives offer impressive transfer rates.

Benchmark Results: PCMark 7

Due to their design as quiet, energy-efficient disks, the Hitachi Travelstar 5K1000, Toshiba MQ01ABD100, and Western Digital Scorpio Blue WD5000LPVT do not stand out in PCMark 7. Meanwhile, the 7200 RPM Hitachi Travelstar 7K750 only manages to eke out a small advantage over the other three disks.
