A paragraph from this Wikipedia article reads:

Quote:
While live recording has migrated to solid state (Panasonic P2, Sony SR MASTER or XDCAM-EX), optical disc (Sony's XDCAM) and hard disks, the high cost of solid state and the limited shelf life of hard-disk drives make them less desirable for archival use, for which tape is still used. News and production camera crews in 2013 still have cameras that use tape formats, even in HD.


Scott, can you possibly tell me the average shelf life of an Enterprise-class hard drive? How about the average shelf life of an SSD?

I would rate the shelf life just about the same as the usable life. According to information published by Backblaze drives have a median lifespan of over 6 years, which means in that time about half will fail. Past that point you have a greater chance of failure than survival. According to a study by Google SSDs seem to last longer but they also have reliability problems that increase with age. Scott.

Scott, is it a good idea to replace hard drives every six years even if they are Enterprise-class drives and even if they are not hooked up to a system most of the time?

Not necessarily. If the drives are not in a mission critical system and especially if you have multiple backups of all the data then I generally continue to use them. I treat all drives as if they will fail at any moment. Scott.
