Seagate Momentus 7200 750GB SATA Notebook Hard Drive

Seagate may call this a laptop hard drive but of course the applications can go much further. They should just take the word Laptop out of the product description and call it a 2.5" hard drive. After all, this drive can be used in everything that can accept a normal 2.5" hard drive from external enclosures to the Sony PlayStation III, Even a desktop PC if you wanted to go that route. But of course, we need to see some performance numbers before we decide exactly where to put it.

Testing:

CrystalDiskMark3:

CrystalDisk Mark is a free program that measures sequential reads/writes speed and random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed.

Up first we'll put the Western Digital Caviar Black. Aside from the Raptor-X, the Caviar Black represents Western Digital's flagship mainstream consumer hard drive.

Who thought that comparing a performance based desktop drive to a laptop drive was going to 2.5" slaughter? The newer tech of the Seagate may blend well with synthetic benchmarks, but each drive was on equal ground.

The 5400 RPM Hitachi 5K500 struggled to meet the raw sequential reading and writing speeds of the Seagate Momentus and the Western Digital Black, but that's to be expected. Still, the Hitachi's native command queuing deserves some honorable mention.
