Specifications and Feature Set Comparison

Prior to getting into the performance evaluation, we will take a look at the specifications of the WD Red Pro 6 TB and see how it compares against the other NAS-specific hard drives that we have looked at before.

The WD Red Pro 6 TB sports a SATA III (6 Gbps) interface. As is customary for the high capacity drives in this market segment, it can only emulate 512-byte sectors (natively 4K). The interesting aspect is the presence of a 128 MB cache similar to the Seagate and HGST drives, and unlike the WD Red. The obvious selling point for its price target is the 7200 RPM speed, which should easily give it the lead in most benchmarks over the WD Red. The other aspects (such as the URE ratings, MTBF, warranty etc.) are as expected for a drive targeting SMBs and SMEs. The table below presents the data for the drive against the others in our evaluation database.

    It would be even louder with four of these WD Red Pro drives!

    The problem might also lie with your NAS: insufficient decoupling will lead to very nasty vibration, as is insufficient dampening or the use of not stiff enough components.

    Well with the Pro only $33 more it's a no brainer. The 5 years warranty alone will make that a profitable investment alone.

    Important details are missing from the article. It should be the first thing covered for drives of such capacities - make it clear if they are using a shingled write method requiring rewrites of large blocks for small random writes.

    anyone remember when all seagate consumer drives had 5 year warranties.. it was great. now we are lucky to get a 3 year warranty.

    planned obsolescence is a wonderful thing. just ask Apple.
  • star-affinity - Tuesday, September 8, 2015 - link

    In what way is Apple worse than others when it comes to ”planned obsolescence”?
  • valinor89 - Tuesday, September 8, 2015 - link

    As far as I know Apple was the first mass consumer company to embrace the practice. Or at least the best known for it. Usually gadgets of other companyes were expected to be superceeded by advancing technology, not designed to fail after x time... One of the most famous examples was the Ipod Nano case.

    The practice existed before but apple put it in the spotlight.

    Apple is rarely the first to do anything. They certainly weren't the first to embrace planned obsolescence.

    Why not moving to a 10gbe for the nas test? I think that for a soho scenario could make sense, with a direct 10gb connection between workstation and nas and classic 1gb link among remaining clients. Just my 2 cents
