The USB-IF organization recently announced the upcoming launch of the USB4 v2.0 specification, which is an upgraded version of the USB4 specification, mainly adding an 80Gbps active cable standard, doubling the speed and making it the fastest interface at present.
Counting USB4 v2.0, plus the existing USB 1.1 to USB4, as well as the thunderbolt interface, there are at least six or seven types of USB interfaces that everyone can see.

SSD alignment mostly refers to SSD partition 4K alignment because SSD adopt the smallest 4K sector in file system to save data. If the smallest 4K allocation units are not always aligned with the 4K pages in SSD, the performance of SSD could be affected. 4K alignment also is widely used in advanced formatted mechanical hard disk. 4K aligned partition better serves operating systems and offers higher performance. One may need to align Windows 10 after clone. There are some signs that show your SSD alignment not OK. For instance, known small file occupies large disk storage in data partition, or system programs and applications run slowly even if you just upgrade hard drive to SSD. If things continue this way, the number of unnecessary writing operations will increase dramatically, which shortens SSD lifespan eventually. ...

A hard disk drive (HDD) is a non-volatile computer storage device containing magnetic disks or platters rotating at high speeds. It is a secondary storage device used to store data permanently, random access memory (RAM) being the primary memory device. Non-volatile means data is retained when the computer is turned off. A hard disk drive is also known as a hard drive. Learn more here  https://www.ankmax.com/newsinfo/1632698.html
