Disk Reliability Trade-Offs?
I just ordered a diskless ReadyNAS 314 from Amazon. The plan is to implement a RAID 10. Since I have had a terrible experience with the disks, I am researching this aspect very carefully. My 3 t...
Personally I haven't seen much evidence that enterprise drives are more reliable than consumer drives, though of course they are marketed as such.
I also haven't seen much evidence that higher density drives are more prone to failure. Tolerances of course are tighter with higher density, but that doesn't necessarily mean higher failure rates.
I've had good luck with the WDC Reds (and with WDC in general). I've had a lot more failures with Seagate, and over time have replaced failed Seagates with WDC.
I agree on the need for backup. The simplest way to back up a NAS is to another NAS. For instance, add an RN104 to the mix. RN104+RN314 with NAS drives would be more robust then RN314 with enterprise drives. The RN104 could use jbod, so it would only need two disks in your configuration.
Also, I am wondering why you are going with RAID-10 and not RAID-6?
