A paragraph from this Wikipedia article
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?
