Western Digital's Performance-Oriented 4 TB Hard Drive
Western Digital recently added a new model to its Black family of performance-oriented hard drives. The new disk, technically referred to as WD4001FAEX, sports 4 TB of space. It spins at 7,200 RPM, employs a 6 Gb/s SATA interface, and includes 64 MB of cache.
Although the company won't divulge how many platters this behemoth uses to hit its capacity ceiling, our benchmark/power data suggests the magic number is five. You can’t tell by simply looking at it; the drive is 26.1 mm-thick, just like many other 3 and 4 TB repositories.
As a general rule, the more capacity a hard drive hosts, the longer it takes to benchmark. Western Digital's WD4001FAEX is certainly no exception. It took us 19 hours of testing to get a complete picture of its performance. Fortunately, the company kept this in mind when it sent out samples, providing us with some much-needed sugar. It's too bad that you don't get chocolate as part of the disk's standard bundle. When you spend $330, a bare 4 TB hard drive is all you get.
