Western Digital Caviar Green (1TB) review

Price when reviewed

The 1TB Caviar Green drive comes with the same “green” features as the rest of the range: the trio of platters spin at an undisclosed speed, set somewhere between 5,400 and 7,200rpm, and other features work to lower power requirements. The result is an excellent power draw of 4W.

Western Digital Caviar Green (1TB) review

Performance was decent, too. Our file read test returned a decent result of 70.7MB/sec, with a write speed figure of 63.8MB/sec – perfectly respectable for a drive with green ambitions.

Other results are less impressive, with disappointing access times and average sequential read speeds seeing the 1TB Caviar Green slip down our results table.

It’s excellent value, though. At £69 the Caviar Green costs a mere 7.4p/GB, and is one of the cheapest drives on test this month. Consider this alongside the environmental features and low power draw and, if speed isn’t your main concern, it’s a cheap way to get 1TB of storage.
