ReadyNas Ultra Drive Failure Rate

I suppose I could have posted a similar topic back in June, 2007 when I set up my trusty old NV+ with two Seagate 500GB drives, and had one fail within the first 30 days. But, I was more concerned about getting a replacement drive which I did at a local retail store. After it resynced and everything was back up, I RMA'd the drive and shortly thereafter received a replacement. That drive (a refurbished 750GB, I guess they were out of 500 GB drives) was used in other service, and the two 500GB drives in my NV+ ran for the next 3 years without any problems. In fact, they are still in other usage. They were removed with over 25,000 hours of use only because I was taking my NV+ to 1GB drives.

All drives can and will fail, usually at the most inopportune times. That is why the RAID system was developed. As Ukyo has pointed out, even the more expensive Enterprise class drives, while reducing the chance of failure, will still at times fail.
