I wouldn't be too fussed about 7x24 rating in a home server.

I still have a set of 10 regular Seagate drives I bought in 2007 that were
spinning non stop for four years in a very hostile environment (my garage!).
They simply refuse to die and I'm still using them in various test systems.

Of course, your mileage will vary. Lately I've been having better luck with my 500 GB WD Blue drives, while in two systems I have recently replaced dying Segate 500 GB drives (7200.11) from 2009. One was part of a ZFS mirror, and the other a Linux mdraid mirror.

The drive in the OI box had a very large number of reallocated sectors and finally showed a bad SMART status (but no ZFS checksum errors on scrub). The drive in the Linux system started throwing read errors, yet had few reallocated sectors and still showed "PASSED" in the SMART data. Worse, it FAILED to reallocate sectors!

If you're running 2009-vintage 7200.11 Barracudas, be prepared to replace them soon if you haven't already done so.
