A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
i-RAM – a DRAM-based solid-state storage device produced by Gigabyte, operating as a SATA hard disk drive; Magnetic storage – the concept of storing data on a magnetised medium using different patterns of magnetisation; RAM drive – a block of random-access memory that the operating system treats as if it were secondary storage
S.M.A.R.T. drives may offer a number of self-tests: [104] [105] [106] Short Checks the electrical and mechanical performance as well as the read performance of the disk. Electrical tests might include a test of buffer RAM, a read/write circuitry test, or a test of the read/write head elements. Mechanical test includes seeking and servo on data ...
SCSI, SAS, and FC drives are more expensive than consumer-grade SATA drives, and usually used in servers and disk arrays, where SATA drives were sold to the home computer and desktop and near-line storage market and were perceived to be less reliable. This distinction is now becoming blurred.

The latest survey, which was compiled from members who bought more than 760,000 new laundry and kitchen appliances between 2009 and 2020, shows “how reliable one brand is relative to another ...
The first devices resembling solid-state drives (SSDs) used semiconductor technology, with an early example being the 1978 StorageTek STC 4305. This device was a plug-compatible replacement for the IBM 2305 hard drive, initially using charge-coupled devices for storage and later switching to dynamic random-access memory (DRAM).
An mSATA SSD on top of a 2.5-inch SATA drive. Serial ATA (SATA). The SATA data cable has one data pair for differential transmission of data to the device, and one pair for differential receiving from the device, just like EIA-422. That requires that data be transmitted serially.
