Western Digital Caviar Green 3TB Hard Drive (Page 4)

TweakTown Rating: 88%Manufacturer: Western Digital


We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: AVADirect, GIGABYTE, Cooler Master, LSI and Noctua.

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

Since most users will use the Western Digital Caviar Green 2.5 and 3TB drives with the included Highpoint HBA, we used that for our testing instead of our on board or aftermarket controllers. With a new controller also come new variables, the things I don't like adding to my reviews since it removes the equal playing field I strive for. The two comparison drives being shown in the review were tested on the GIGABYTE on board Marvell controller. They are also SATA 6Gbps drives, so this is their native partner.

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.


In ATTO we see the Western Digital Caviar Green ramping up speeds quickly. The 4k test shows impressive write speeds of just over 60MB/s and read speeds close to 75MB/s. Western Digital didn't claim any data transfer performance numbers in their marketing material, but it looks like those would be 125MB/s read and 120MB/s write.
