What is the interface of the solid state drive


We know that SSDs are the fastest and the speed is nearly twice that of the mechanical hard drives we know. In the whole DIY computer hardware, the development speed of the hard disk can be said to be very slow, far lower than the update speed of other hardware, which mainly depends on the structure of the traditional hard disk, and the development has been close to the peak so far, it is difficult to speed up. It is. This has also led to the fact that today's traditional mechanical hard drives are becoming bottlenecks in computers, affecting the speed of computers. However, with the emergence of new SSDs with better performance, SSDs are expected to break the bottleneck of the difficulty of speeding up traditional hard drives. However, SSDs are still in the initial stage of development, and there are still insufficient capacity. No more nonsense, return to this article. The topic, then what is the interface of the SSD?

What is the interface of the SSD?

In fact, SSDs have several interfaces, and SSDs will vary according to different applications. interface. Compared with traditional mechanical hard disks, SSDs are more likely to be confused by the first-time users. The following are introduced separately:

Mainstream commonly used--SATA interface

SATA interface is no longer New technology, from the introduction of SATA 1.0 in 2001 to the current SATA2.0 and SATA3.0, has made SATA the main interface of the current SSD. As far as the current usage rate is concerned, SATA2.0 users are still the most, which is mainly affected by the PC interface, but most of the SATA3.0 products currently on the market are backward compatible with 2.0.

SATA Interface

SATA interface solid state drives, mostly used to replace mechanical hard drives, our desktop upgrades mainly use such interfaces. With the introduction of SATA 2.0 and 3.0, the transmission rate has grown to 300 and 600 MB/s, which is the earliest PATA interface, which is not comparable to the IDE interface.

Although the SSD of the SATA interface is currently dominated by SATA 2.0, SATA 3.0 is relatively low, but its transmission rate of up to 600MB per second is destined to become the future interface trend of SSD.

More Server Classes--PCI-E Interfaces

PCI-E Interfaces

Compared with SATA interfaces that are more in contact with each other, PCI-E is mainly used internally. Embedded application. Although SSD replaces the low speed of mechanical equipment with physical equipment compared to mechanical hard disks, SSDs are again limited by physical size and data interface during performance improvement. The PCI-E interface has more bandwidth than SATA, which can further improve performance and capacity, and give full play to the potential of SSD.
