Not all SSDs and laptop hard drives are universal in size.
1. The vast majority of SSDs and laptop hard drives are 2.5 inches.
2, but there are a small number of laptop hard drives that are 1.8 inches, or even smaller microdrives. Used for ultra-thin or shaped laptops.
3, solid state drives in addition to the 2.5-inch Sata interface, there are 1.8-inch msata solid state drives and smaller m.2 solid state drives.
Expanded profile:
Solid State Drives (Solid State Drives), referred to as Solid Disk, Solid State Drive (Solid State Drive) with a solid-state array of electronic storage chips and made of hard disk, by the control unit and storage unit (FLASH chip, DRAM chip). Solid State Drive in the interface specifications and definitions, functions and methods of use with the 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.
