The Types of Hard Disk Enclosures
According to the size of the hard disk, it is divided into three types, 3.5-inch hard disk enclosure, 2.5-inch hard disk enclosure, and M.2 hard disk enclosure.
① The 3.5-inch hard disk box is relatively large and usually has a power adapter, and is mainly used for mechanical hard disks. Most of the internal interfaces on the market today are SATA 3.0 interfaces, with a theoretical transfer rate of 6Gbps.
② 2.5-inch hard disk enclosures are much smaller than 3.5-inch hard disk enclosures. They are also the most widely used type of hard disk enclosures. They are mostly used for solid-state drives, with a theoretical transmission speed of 6Gbps.
③ The M.2 solid-state hard disk box, like its interface, is divided into two types, one is the M.2 NGFF hard disk box that uses the SATA bus or the PCIe*2 bus, and the other is the M.2 NGFF hard disk box that uses the PCIe*4 bus. .2 NVMe hard disk enclosure.
