WD Se Enterprise Hard Drive

With its “Se” series of enterprise hard drives, WD is targeting those in need of “bulk storage”, whether it be in a datacenter or NAS. Its biggest perk is that it almost perfectly mimics the company’s Re drives, boasting a 5-year warranty, models ranging from 2 – 4TB, and best of all, a price tag of up to $80 less.

Synthetic: HD Tune Pro 5.0

One of the best-known storage benchmarking tools is HD Tune, as it’s easy to run, covers a wide-range of testing scenarios, and can do other things such as test for errors, provides SMART information and so forth. For our testing with the program, we run the default benchmark which gives us a minimum, average and maximum speeds along with an access time result, and also the Random Access test, which gives us IOPS information.

HD Tune Pro 5.0

The Se drive continues its impressive performance trend here, scoring the best minimum results among the sub-10K drives, and great average speeds overall. Access times-wise, the Se performs well, but falls quite a bit behind the Re with regards to the writes.

Can someone please explain this one? Up to this point, the Se drive hasn’t performed too different than the Re, but here, it even surpasses the VelociRaptor in some regards. It’s performance so good, that either WD packed in 1TB platters (unlikely, given that’d be a first for a 7,200 RPM drive), or the company specifically tuned the firmware for IOPS performance. The latter explanation would make sense, given these drives are suited for potential cloud storage and large NASes.

    “Power-On Hours 8760″ what is this?

      A fancy way of saying 24/7 operation (8760 / 24 = 365).

    I’ve now switched entirely to the WD Re disks for _all_ of my storage needs..they really are built insanely well, not to mention they have much better heat dissipation than the equivalent consumer drive (this is especially true for the 250GB and 500GB units!). The Se is just as compelling.

      I agree. It sucks to cough up the extra $$$ for the drives, but they’re built for long life and constant use.
