Sigh. No. Really, go look at the data. I am not going to take the "consensus" of the anand crowd over it.
Hitachi Deskstar 7K2000 is a consumer-grade non-enterprise hard drive. In the sample of ~4,600 drives it has 1.1% annual failure rate in the NAS environment.
Seagate Barracuda 7200.14 is a consumer-grade non-enterprise hard drive. In the sample of ~1,200 drives it has 43.1% annual failure rate in the NAS environment.
Those are VERY VERY DIFFERENT failure rates.
I, for example, have five-drive zfs array at home which is on 24/7. I am very much interested in what kind of drives will give me a 1% failure rates and which kind of drives will give me 43% failure rates. I am not average, but I hardly think I'm unique in that respect in the LW crowd.
Do we actually disagree about anything?
We certainly agree that the Barracuda's are crap in NAS's. I believe that WD Red's are a major improvement and Hitachi Deskstars a further improvement, which is just reading the Backblaze data (which is eminently applicable to NAS environments), so I'm we're in complete agreement that, for NAS's, Barracuda << Red < 7K2000.
However, I also contend that, in a desktop PC, a lot of what makes the Reds and 7K2000 more reliable (e.g. superior vibration resistance) will count for very little, so they'll still fail le... (read more)
