WinBench 99 measures the Caviar WD1000BB's access time at 13.4 milliseconds, a scant 0.1 ms higher than its predecessor. This places the 1000BB at the upper end of a group of drives tightly bound within the lower 13ms range. Subtracting 4.2 milliseconds to account for the average rotational latency of a 7200 RPM drive yields a measured seek time of 9.2 milliseconds, a bit off of the 8.9 ms claim.

Ever since the WD400BB, WD's 7200 RPM caviar series lagged the pack when it came to sequential transfer rates. The 800BB, for example, brought up the rear when compared to contemporary drives that featured lower areal density. The 1000BB, however, finally brings the Caviar series up to the front of the pack. Outer-zone transfer rates weigh in at 43.7 MB/sec, the highest we've seen in an ATA drive. Inner-zone transfer rates are also impressive... the 1000BB bottoms out at 27.9 MB/sec.
