Western Digital Caviar Black 2TB Hard Drive Review

ATTO Disk Benchmark

The ATTO disk benchmark tests the drives read and write speeds using gradually larger size files. For these tests, the ATTO program was set to run from its smallest to largest value (.5KB to 8192KB) and the total length was set to 256MB. The test program then spits out an extrapolated performance figure in megabytes per second.

Read

As expected, all of the hard drives are about the same in ultra small reads and it is only when we get to about the 8kb size does this drive start to pull ahead….and destroy the competition. Sure, newer generation SSDs are still in a league of their own, but appears the Black 2GB has carved out a whole new high water mark for hard drives.

Write

Once again the Western Digital 2TB Black destroys all other hard drives starting at about the 8kb mark. This drive really is a beast when it comes to synthetic tests and we are REALLY looking forward to seeing what the IOMeter results look like.
