Seagate Momentus XT 500GB review

A mutant hard drive born of SSD toxic waste

Seagate momentus xt

We've pitted the Momentous XT against one of the best traditional desktop drives around, a 1TB Hitachi Deskstar with 16MB cache, and OCZ's supremely powerful 120GB Vertex 2 SSD.

We didn't expect the Momentous XT to win any of the tests against these two leaders in their respective fields, rather we wanted to show how close it is to the top despite its hybrid nature.

It's worth pointing out that the Vertex 2 currently costs £258, so we've also included a more realistic SSD, the Kingston V+ for comparison.
