With SANDRA's physical disk benchmark, we find the 3TB Hitachi Deskstar offers the highest write performance at 128.77 MB/s. Seagate's drive edges out the Deskstar with read speed at 123.3 MB/s. Both Western Digital drives offer almost identical performance, but the AV-GP does show a tiny lead over the Caviar Green.
