WD RE 4TB Enterprise-Class HDD Review
Western Digital’s 4TB WD RE SATA drive certainly satisfies the need for capacity. And at a 7200RPM spindle speed with a SATA 6Gbps interface, 64MB of cache, and up to 171MBps sustained transfer rates, the performance balance is there as well. In the enterprise, though, there’s a third consideration that can trump the other two: reliability.
IT folks are concerned with, among other things, hardware lifecycles, the frequency of data corruption and drive failures. Selecting storage components that can endure under the strain of enterprise-level workloads without failing or causing problems is paramount, both to the IT department’s hardware budget and to the man hours it must expend to effectively manage the company’s data.
WD built this drive with a number of features designed to meet those requirements.
3.5-inch (5 platter design, 800GB/platter)
up to 171MBps sustained
1.2 million hours
$464.99-$520.99 (street prices)
To further protect the drive, WD included a multi-axis shock sensor to adjust for any shock events as well as StableTrac technology that reduces vibrations by securing and dampening the motor shaft at both ends.
Note that there are other iterations of the WD RE that come in 3TB, 2TB, 1TB, 500GB, and 250GB capacities as well, in addition to 4TB and 1TB WD RE drives with SAS interfaces.
