HGST hard drives

[oj88]

For what purpose do you wish to use the drives for? There are different models that are purpose-built depending on your application.

IMO, all hard disks fails.... whether it be consumer or enterprise class. MTBF means nothing if for instance, you got a lemon or somebody during the manufacturing or handling of the drive bumped or dropped it. To prevent data loss, ideally some sort of redundancy and backup strategy should be used.

I've had a Hitachi 1TB desktop drive that failed within 8 months. The replacement drive, same Hitachi model, is still running for 3 years now.

I used to be a Seagate fan until about 3 years ago. I've discovered that when Seagate drives fail, they're usually the catastrophic kind; One day it's working but on the next power-up, you're greeted with a clicking, undetected, and inaccessible drive.

On the other hand, WD seems to be the opposite. When my WD fails (I used to have a lot of WD Green drives), it does so with plenty of warning.... A few bad sectors starts popping up, giving you enough time to salvage whatever data that can still be read. It's by no means an alternative to backing up, but it saves time not having to resort to restoring the whole drive from backup.

For that reason, on my home server (24x7 for 4 years now), I switched to WD Red drives (5 of them totaling about 16 TB). I don't work for WD but I really swear by their Red (NAS) drives.
