HotHardware published a review on the WD RE 4TB Enterprise-Class HDD
When considering a new storage solution, most users try to find the right balance between speed and capacity. SSDs are super fast, no doubt about it, but an HDD spinning at 7200RPM or 10,000RPM will still offer solid performance, and you have access to dramatically more storage capacity for a far lower cost per GB compared to an SSD.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.
