WD Caviar Green 3TB Hard Drive Review
Our Test Methodologies: Under
each test condition, the drives tested here were installed as secondary
volumes in our testbed, with a different hard disk used for the OS and
benchmark installations. The drives were left blank without partitions
wherever possible, unless a test required them to be partitioned and
formatted, as was the case with our ATTO and Vantage
benchmark tests. Windows firewall, automatic updates and screen savers
were all disabled before testing. In all test runs, we rebooted the system and waited several minutes for drive activity to settle before invoking a test.

ATTO
is a more straight-forward type of disk benchmark that
measures transfers across a specific volume length. It measures raw
transfer rates for both reads and writes and graphs them out in an
easily interpreted chart. We chose .5kb through 8192kb transfer sizes
over a total max volume length of 256MB. This test was performed on
blank, formatted drives with NTFS partitions.

Right from the start, the Caviar Green 3TB did well with very small transfer sizes. Unfortunately, that advantage quickly disappeared once we get over 8kb files. By the end of the benchmark, the drive recorded 139MB/s read and 106MB/s write speeds.
