The main types of hard disk interfaces currently available are IDE, SATA, SCSI, SAS, FC, and so on.

The IDE is commonly known as the port, SATA is commonly known as the serial port, both of the hard disk is the PC and low-end server common hard disk.

SCSI is the abbreviation for "Small computer system dedicated interface", which is the hard disk with this interface.

SAS is the SCSI interface of the serial port. The general server hard disk uses these two kinds of interface, its performance than the above two kinds of hard disk to be high, the stability is stronger, but the price is high, the capacity is small, the noise is big.

FC is a fibre channel, and the Scis interface is the same as the fiber channel is not designed for the hard disk design and development of interface technology, is specifically designed for network systems, but with the demand for speed of the storage system, is gradually applied to the hard disk system.

SSDs, also known as electronic hard disks or solid-state electronic disks, are hard disks made up of control units and solid-state storage units (DRAM or flash chips). SSD interface specification and definition, function and use of the same as the ordinary hard disk, in the product shape and size is also consistent with the ordinary hard disk. The new generation of SSDs generally uses the SATA-2 interface. But its cost is higher.
