What does server disk IO mean? Performance difference between SATA and SSD

IO is actually a computer term, also written as I/O, referring to input/output (Input/Output). Hard disk IO refers to the speed of reading bytes, that is, the ability to read and write hard disks. Today we mainly talk about server disk IO. The performance of server hard disk IO is also an issue that needs to be considered in server hardware configuration. Where is the performance difference between SATA and SSD?

First of all, the data of the hard disk is stored on each sector in the hard disk drive, and a sector is a disk area divided by a certain magnetic density as an interval. Reading the content of a certain sector from the disk is a process in which the hard disk issues IO commands.

 

The disk receives instructions and chooses to read or write data. If the read and write speed is fast, that is, the hard disk IO performance is high. Of course, there are many factors that affect the read and write speed. Hard disk performance optimization skills are also a university question, but when we choose a hard disk, we only need to know a little bit to know the performance of the hard disk IO, that is the price.

But when it comes to the choice of hard disk, the server hard disk provided by Chiwang Technology is mainly SATA (Serial Advanced Technology Attachment)  and SSD (Solid State Drives)  .

SSD is also called solid-state hard drive, which has the advantages of fast read and write speed, short access time, low power consumption, no noise, anti-vibration, low heat, small size, and wide operating temperature range. Compared with it, its cost will be slightly higher .

SATA, a mechanical hard disk, has a faster transfer rate and a larger storage space. It is suitable for ordinary users and has an advantage in price. Thank you for reading. If you want to know more about server technology dry goods, you can leave a message and private message me.
