SSD solid state is the development trend of hard drives, breaking the performance bottleneck of traditional mechanical hard drives. Nowadays, regardless of whether it is a new installation or an upgrade of hardware, SSD solid state drives are given priority to improve the computer's read and write speed.
Compared with the traditional HDD (mechanical hard disk), the biggest advantage of SSD is that it is much faster. If the old computer is replaced with an SSD, the boot speed, game loading, and fluency will be significantly improved, while the newly installed solid state drive is already standard.
We have a special liking for memory sticks. When the computer is stuck, we will directly install memory sticks. If the game is not running smoothly, we will directly install memory sticks. In short, many people think that computer memory sticks are like the "savior of the computer".
The IO scheduling of SAS and SATA interfaces requires the use of elevator algorithms to rearrange the IO to optimize the path of the magnetic head; the Raid card is used for data protection.In terms of interface protocol, with the invention of SSD, NVMe protocol came into being.
