A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, or solid-state disk. [1] [2] SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells. The performance and endurance of ...
In the list those manufacturers that also produce hard disk drives or flash memory are identified. Additionally, the type of memory used in their solid-state drives is noted. This list does not include the manufacturers of specific components of SSDs, such as flash memory controllers. [1]
HGST, Inc. (Hitachi Global Storage Technologies) was a manufacturer of hard disk drives, solid-state drives, and external storage products and services. It was initially a subsidiary of Hitachi, formed through its acquisition of IBM's disk drive business. It was acquired by Western Digital in 2012. However, until October 2015, it was required ...
The first, the SSD 510, used an SATA 6 Gigabit per second interface to reach speeds of up to 500 MB/s. [14] The drive, which uses a controller from Marvell Technology Group, [15] was released using 34 nm NAND Flash and came in capacities of 120 GB and 250 GB. The second product announcement, the SSD 320, is the successor to Intel's earlier X25-M.
Single-layer HD DVD and Blu-ray disks offer densities around 7.5 Gbit/in 2 and 12.5 Gbit/in 2, respectively. When introduced in 1982 CDs had considerably higher densities than hard disk drives, but hard disk drives have since advanced much more quickly and eclipsed optical media in both areal density and capacity per device.
