PCI Express bus is used for the communication between PCI-E interface SSD and motherboard, while SATA serial bus is used for the communication between SATA interface SSD and motherboard. These two buses are opposite to each other. The high-end PCI-E interface solid-state drive can even provide more than sata3.0 because of the large number of PCI-E channels used 0 interface SSD speed.
The difference between PCI-E interface SSD and SATA interface SSD mainly lies in different interfaces and different communication buses. For notebook computers, the PCI-E interface solid-state disk is mainly used for the configuration of multi hard disk system, and the PCI-E slot is different from the standard SATA; The SATA interface SSD is generally used to replace the original mechanical hard disk in the notebook to improve disk performance.
PCI-E is the current mainstream bus and interface standard. Its original name is "3gio", which was proposed by Intel. Obviously, Intel means that it represents the next generation I / O interface standard. The new standard will completely replace the current PCI and AGP, and finally realize the unification of bus standards, that is, there will be no so-called graphics card special interface AGP for the future motherboard interface, and all interfaces are PCI-E interfaces, whether network cards or graphics cards
