How many desktop SSD interfaces are there

Solid State Drive several interfaces

6 kinds.

1, STAT interface, the transfer speed is 6Gbps, used for older desktop machines.

2, mSATA interface, the transfer speed is 6Gbps.

3, SATAExpress interface, the transfer speed can be up to 12Gbps.

4, PCI-E interface, the transfer speed is up to 32Gbps.

5, m.2 interface, the speed is 10Gbps and 32Gbps.< /p>

6, u.2 interface, is the fastest transfer speed in SSD, reaching 32Gbps.

Although the SSD interface type is complicated, but summarized down to SATA6Gbps, msata, M.2, and PCI-E is the main, and on the current technology maturity and cost-effective and so on many aspects, M.2 and SATA6Gbps interface has the absolute market share.

Solid State Drive (SolidStateDisk or SolidStateDrive, referred to as SSD), commonly known as solid state hard disk, solid state hard disk is an array of solid-state electronic storage chips and made of hard disk, because the solid capacitors in Taiwan’s English called Solid and got the name. SSD by the control unit and the storage unit (FLASH chip. DRAM chip), DRAM chips). Solid state hard disk 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 many other fields.

The operating temperature range of its chips is wide, commercial-grade products (0 to 70°C) industrial-grade products (-40 to 85°C). 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 given rise to a number of emerging memory manufacturers. Manufacturers can build SSDs by simply purchasing NAND memory and matching it with an appropriate control chip. The new generation of SSDs commonly use SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface, SFF-8639 interface and M.2NVME/SATA protocol.

How many SSD interfaces are there

There are five.

The M.2 interface is a new host interface program that is compatible with a variety of communication protocols, such as sata, PCIe, USB, HSIC, UART, SMBus, and so on.

For desktop users, the SATA interface is already sufficient to meet the needs of most users, but taking into account the storage needs of Ultrabook users, Intel has eagerly introduced this new interface standard. So, we have seen this new M.2 interface on the new 9 series motherboards released by Asus, Gigabyte, MSI and others, which are now popularized.

Extended Information

The M2 interface transfers more than SATA3:

SATA3 is 6Gb/s, which is equivalent to is 750MB/s transfer rate.

M2 is 10Gb/s, which is equivalent to 1.25GB/s transfer rate.

Higher-spec enterprise SSDs are faster with the M2 interface, while regular home SSDs are still faster with SATA 3.0 because of the low material.

How many SSD ports does the host have

Four. The SATA ports are the most common SSD ports, and there are usually four of them, one of which has a hard drive already plugged into it, one of which has an optical drive plugged into it, and two of which are empty, allowing you to increase the number of hard drives directly.
