Power On Hours

That's 383 and a third days.

Drive warranties do vary and some are designed for 24/7 operation while others aren't. What models do you have and how long have you had them?

I have the Seagate 1.5T ST31500341AS which were put into operation in May 2011.


Thanks,

Do you have any SMART errors on the disks?

One Reallocated Sector on drive one and three Reallocated Sectors on drive 2. Nothing has changed In more than a year..

Drives should be good for a while yet unless the reallocated sector count or ATA error count starts increasing rapidly.

Thanks for the info....I will continue my backups and hope these drives go for another year or 2....

I had two Seagate ST3500630AS drives that ran for over 25,000 hours or almost three years of 24/7 operation and were removed only to replace them with 1TB drives. In fact they are still in use in other service.
