The only reviews I seem to find on the sizes hard drives I'm interested in, namely < 1TB, done within the last year are all on the caviar SE16 640. Every series which has had a 1 TB come out in that period, such as the F1 and 7200.11 has had the 1TB reviewed and compared exhastively. Am I just not googling well ? There are big performance variations between sizes, which explains why the SE16 640 has been well received, right?
