Why would you compare the drives in Apple *servers* with the drives in
Dell *cheapo* boxes?

Dell workstations and servers pretty much use the same parts Apple does.

The RE feature list: secure SATA connector, TLER (time limited error
recovery), diagnostics, 1 million hour MTBF, fluid bearings.

Seagate (for example) has had all of those features in their normal
drives for years now, except for two: TLER and secure SATA connector.

The secure SATA connector is nice, though SATA seems to hang on pretty
tightly anyway.

TLER is interesting: WD's error correction has in the past been
incompatible with RAID error correction. TLER is supposed to fix that.

However, as far as I know other drives don't have this problem with
their error recovery firmware in the first place.
