Remember when 500GB was the most you could get from a notebook drive? It seems like most vendors have made the transition to 640GB. Western Digital even has its own 750GB model that fits within the 9.5 mm z-height. So, which of these drives is the best?

Benchmark Results: Access Time And I/O Performance

Access Time

The access time test is dominated by Samsung and Toshiba.

I/O Performance

It seems that only the Toshiba GSX and Seagate Momentus 5400 were optimized for I/O performance. The two other drives fall behind a bit. Samsung’s Spinpoint M7E in particular isn’t strong at I/O-intensive activity.
