You can read more about TweakTown's Storage Product Testing Workstation and the procedures followed to test products in this article.

The Western Digital Red is built for NAS environments but we couldn't help ourselves and ran a 1TB capacity size through our standard desktop tests.

ATTO Baseline Performance

Version and / or Patch Used: 2.34

ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.

Using ATTO we see the 5K4000 ramping up speed very quickly in the block sizes. Read performance nearly reaches peak at 4K and write speed hits its stride at 8K. The read and write best case performance is roughly 130MB/s.
