What is the difference between ordinary SSD and ultra-high speed SSD?

1. Normal SSD: SSD with SATA interface.

2. Ultra-high-speed solid-state disk: Solid-state disk with M.2 interface specification. Is a new interface specification introduced by Intel to replace MSATA.

Second, the speed is different.

1. Ordinary SSD: The highest reading speed can reach more than 300MB/S, and the writing speed can also reach more than1100mb/s. ..

2. Ultra-high-speed SSD: Support SATA and PCI-E X2 interfaces. If PCI-EX2 interface standard is adopted, the maximum reading speed can reach 700MB/s and the writing speed can also reach 550 MB/s. ..

Third, the advantages are different.

1. Ordinary solid-state hard disk: It has the characteristics of fast reading and writing speed, light weight, low energy consumption and small size that traditional mechanical hard disks do not have.

2. Ultra-high-speed solid-state drive: Like mSATA, NAND flash memory particles can be arranged on one side or on both sides, with the total thickness of single-side arrangement being only 2.75mm and the thickness of double-side arrangement being only 3.85 mm ..
