> That doesn't make sense. Nearline and enterprise drives are large 7k2 drives that come in consumer and enterprise models, such as Hitachi Deskstar and Ultrastar. The latter is said to have better bearings etc, although I don't know the difference for sure. With WDs large drives, most of the difference is said to be in the firmware (such as TLER in the enterprise/RAID drives). Comparing "nearline" and "enterprise" like done here, is merely a comparison of small and large drives, where it's well known that the smaller (less dense) drives have less errors.

Less dense but also the drives are probably the 10k & 15k RPM drives
which have to be built to better tolerances given the expectation
they'll be spinning for most of their five year life.
