It seems that Seagate has sorted the cache issues of its 1TB drive in the transition up the larger capacity, with the cache delivering a very fast burst speed of 248.8 MB/s, making it the fastest cache on a mechanical hard drive we've yet to test - impressive stuff!

The average read across the disk is just as impressive, with a 13.7 MB/s advantage over the Samsung Spinpoint F1 1TB, making the Seagate 1.5TB the fastest mechanical drive we've ever tested, at least in these theoretical tests.

Sadly though the Seagate 1.5TB's response time is a little disappointing at 15m/s - 2.5m/s slower than the Samsung. While this might seem like a very small difference, it will add up when accessing very large groups of smaller files.
