Solid-state hard disk (SSD) is a hard disk composed of an array of solid-state electronic storage chips, which is composed of a control unit and a storage unit (FLASH chip and DRAM chip). Solid-state hard disk is exactly the same as ordinary hard disk in terms of interface, function and usage, and the product shape and size are also exactly the same as ordinary hard disk. Widely used in military, vehicle, industrial control, video monitoring, network monitoring, network terminals, electric power, medical care, aviation, navigation equipment and other fields. There are two kinds of storage media for SSD, one is using FLASH chip as storage media, and the other is using DRAM as storage media. ?
Sandforce SF-2281:Intel 520,525, Corsair GT, Kingston HyperX, used in some Toshiba products. The stability of Intel is self-evident. In addition, SandForce master has a unique data compression function, which can greatly improve the actual speed in daily use (which is why many people think SandForce is not as good as Marvell, but it is faster in actual use), greatly reduce the particle wear of SSD (because the write amplification WA value is relatively low), and improve the particle life.
