The 1? -4 markings are the order of the SATA interfaces, and the BIOS will check these interfaces in order when booting from 1 to 4 in sequence. It should be plugged into the SATA1 interface, and the other SATA interfaces can be connected to other SATA devices.
Solid State Drives (SSDs), also known as solid state disks, are hard drives made with arrays of solid-state electronic storage chips, consisting of a control unit and a storage unit. In the interface specification and definition, function and use of the same as ordinary hard disk, in the product shape and size is also consistent with the ordinary hard disk. It is widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, power, medical, aviation, navigation equipment and other fields.
Solid state hard disk storage medium is divided into flash memory (FLASH chip), DRAM two kinds. Its chip operating temperature range is wide, commercial products 0 ~ 70 ℃; industrial products -40 ~ 85 ℃. Because solid state drive technology is different from traditional hard disk technology, it has generated a number of emerging memory manufacturers. The new generation of SSDs commonly use SATA-2 interface, SATA-3 interface, SAS interface, ?MSATA interface, PCI-E interface, etc. ? [1]
