Interesting....I've seen other really good reviews of the Vertex 2 (primarily the E versions) and indeed I bought a 60GB Vertex 2E on the strength of one. It's certainly snappy enough running Windows 7. ATTO gives 280MB/s read and 260MB/s write but I gather this is something to do with how the SF controller deals with different data compression?
Although now I'm thinking maybe I should have got one of OCZ's bootable PCI-E drives instead!
