Western Digital has decided to toss the Green and go for gold. To do this they have released a pair of 7200 RPM versions of their 2TB drive.
One will be a consumer version called the Caviar Black while the Enterprise edition will be called simply the RE4. Both drives will have 64MB of cache and four 500GB density platters. Both run on the SATA 3Gbps standard so no 6G SATA controller there just yet.
The Caviar will set you back around $300, while the enterprise class RE4 has no official pricing but lists a MTBF (Mean Time between Failures) of 1.2 million hours.
Interesingly enough the enterprise flavor has some good power saving features (active power save) as well as a shock absorbing system too.
WD is certainly looking to cater to the needs of long term reliable storage with these.
