WD's Red 4TB HDD expands on the company's current offering with 33% more raw storage capacity than previously available in the same 3.5" form factor with a 6Gb/s SATA interface. The WD Red line also features 1TB, 2TB, and 3TB models, but now consumers and small businesses with one- to five-bay NAS units can install or upgrade to the full 4TB maximum, the most robust storage capacity in the industry. Other standard features with the Red 4TB are a 64MB cache and WD's Intellipower low power spindle. This Intellipower technology is significant as drives in this segment experience continuous 24x7 operation and are required to consume minimal amounts of energy in order to reduce costs.

As very subtly stated in the 3TB WD RED review, "Intellipower" is WD's marketing crap for 5200 rpm.  WD reds are 5200 rpm drives.




Not for my raid arrays.

You know that's on purpose though. They don't want these in raid arrays.

Yeah, ok. They're 5400rpm drives and only sip 5-6W


As for RAIDing them, that depends what you want to do with them. Seek time is the real killer anyway.


How do they compare with something like Seagate's SSHD range?
