Editor to share with you which types of hard drives can be divided into, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Hard drives are divided into three categories: SATA hard disk, SCSI hard disk and SAS hard disk. The hard disk of SATA interface is also called serial port hard disk, which is the mainstream development direction of PC in the future and has strong error correction ability.

Hard drives are divided into three categories: SATA hard disk, SCSI hard disk and SAS hard disk. The hard disk of SATA interface is also called serial port hard disk, which is the mainstream development direction of PC in the future and has strong error correction ability.

Detailed introduction:

SATA hard disk: the hard disk with SATA interface is also called serial port hard disk, which is the mainstream development direction of PC in the future. Because of its strong error correction ability, errors can be corrected automatically once found, which greatly improves the security of data transmission. The new SATA uses the differential signal system "differential-signal-amplified-system".

This system can effectively filter the noise from the normal signal, and the good noise filtering ability enables SATA to operate at a low voltage. Compared with the transmission voltage of Parallel ATA up to 5V, SATA can operate at a higher speed with a peak-to-peak voltage of 0.5V (500mv). It is more correct to say: peak-to-peak differential mode voltage. The general speed can reach 7200 rpm.

SCSI hard disk: SCSI hard disk is a hard disk with SCSI interface. Advantages: SCSI interface has a wide range of applications, multitasking, large bandwidth, low CPU occupancy rate, and hot plug and so on. Because of its good performance and high stability, it is widely used in the server. Disadvantages: because the SCSI hard drive is very expensive, so the general PC will not use SCSI hard disk. The general speed can reach 10000 rpm.

SAS hard disk: SAS (Serial Attached SCSI), that is, serial connection SCSI, is a new generation of SCSI technology, which is the same as Serial ATA (SATA) hard disk. It uses serial technology to obtain higher transmission speed, and improves internal space by shortening the connection line. Improve the performance, availability and scalability of the storage system. The general speed can reach 15000 rpm or even higher.
