The brand is too cottage and the performance is too poor. And mechanical hard disk than the performance improvement is not a lot.
Solid State Drives (Solid State Drives), referred to as solid state disk, solid state hard disk (Solid State Drive) with solid state electronic storage chip array and made of hard disk, by the control unit and storage unit (FLASH chip, DRAM chip) composition. Solid State Drive in the interface specifications and definitions, functions and methods of use and ordinary hard disk is identical, in the product shape and size is also completely consistent with the ordinary hard disk. It is widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and other fields.
The operating temperature range of its chips is wide, commercial-grade products (0~70℃) industrial-grade products (-40~85℃). Although the cost is higher, it is gradually popularizing to the DIY market. Because SSD technology is different from traditional hard disk technology, it has generated a number of emerging memory vendors. Manufacturers can build SSDs by simply purchasing NAND memory and matching it with appropriate control chips. The new generation of SSDs commonly use SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface and SFF-8639 interface.
DRAM-based SSD: Using DRAM as the storage medium, it has a narrower range of applications. It emulates the design of traditional hard disks, can be used for volume setup and management by the file system utility of most operating systems, and provides industry-standard PCI and FC interfaces for connecting to host computers or servers. Applications can be categorized as SSD drives and SSD drive arrays. It is a high-performance memory, and a long service life, the shortcoming is the need for an independent power supply to protect the data security. DRAM solid state drives belong to the more non-mainstream devices.
