SATA disks were introduced in 2005 with the Intel D915PGN desktop motherboard. SATA use 7 data pins while SAS use 14 data pins. Both use 15 power pins. The SFF-8482 connector makes it possible to connect disks to a backplane to simplify replacement.
Generally many data centers use disks for as little as 4 years before they replace them. This is driven more by replacing disks than scaling out with more servers. This censors the actual disk survival times considerably.
SATA DISK RELIABILITY
Remember there are 8,760 hours in a year with 24 hour a day operation. In 5 years, disks rack up 43,800 operating hours.
