ALSO CALLED: Drives
DEFINITION: An SSD (solid-state drive or solid-state disk) is a storage device that stores persistent data on solid-state flash memory. SSDs actually aren't hard drives at all, in the traditional sense of the term, as there are no moving parts involved. Instead, an SSD has an array of semiconductor memory organized as a disk drive, using integrated circuits (ICs) rather than magnetic or optical media. This arrangement  …

A Better RAID Strategy for High Capacity Drives in Mainframe Storage
sponsored by Oracle Corporation
WHITE PAPER: This paper demonstrates that RAID 6 is less capable to prevent data loss with today's large capacity SATA and SAS HDDs. It will also share Oracle's designs to mitigate this risk. The integrity of customers' data is in jeopardy if these large capacity SATA/SAS HDDs are simply packaged into a RAID 6 group without additional mitigation.

DISK DRIVES DEFINITION (continued): …  has many advantages. Data transfer to and from solid-state drives is much faster than electromechanical disk drives. Seek time and latency are also substantially reduced. Users typically enjoy much faster boot times as well. In general, SSDs are also more durable and much quieter, with no moving parts to break or spin up or down. SSDs do, however, have slower write times and a set life expectancy, as there is a finite number of erase/write cycles before performance becomes erratic. Development and adoption of SSDs has been driven by a rapidly expanding need for higher input/output performance. …
