What are the types of hard disk interfaces? Are they any different?

ide...Easy to install, up to 133m s

SATAI installation requires a drive of 150m s

SATATII installation requires 300 ms of driver for non-installed motherboards that may be mapped to ATA100 for use i.e. 100 s

The feature of installing the driver is that there is a button to delete the hard disk on the following icon, because it supports hot swapping, but it is very troublesome and practically unavailable.

There are two types of servers for SCSI servers. . . 160/320m/s

Generally, only 10000-15000 rpm hard disks with ECC inspection are equipped with this interface** its height.

The first 3 are actually about the same in performance, after all, the main thing that affects the hard disk is the speed. They are both 7200 rpm memory, and the average memory is not more than 66M s, so ATA66 is actually enough, if it were not for the existence of the cache, SATA2 would be useless at all.

That's complicated, the main difference is the interface method and the speed.

IDE: The vast majority of hard disks installed on home computers are IDE interfaces. Rotational speed split.

Sata: As the netizen wrote above"Also known as serial port hard disk, it is the trend of PC hard disk in the future. Hot-swappable"Rotational speed split.

SCSI: Mostly hard disks for servers. Rotational speed split.

They have completely different interface pins, and you can't make a mistake. You'd better go to the electronic market and see the real thing.

It seems that there is a serial port and a parallel port! Serial port is traditional! The parallel port seems to transmit data quickly!

IDE and SCSI

SCSI is faster than IDE.

SCSI is generally used for servers or disk arrays.

Serial and parallel interfaces. Its characteristics are basically the opposite.

Interface. SATA interface is the interface with the largest number of users, and SATA interface has strong error correction ability and simple interface, so the number of users is relatively large.

Interface, in fact, IDE represents the type of hard disk, which has been eliminated in the changes of the times.

Interface, SCSI interface hard disk is not used for ordinary PCs, and is widely used for high-speed data transmission on small machines.

4.The Fibre Channel hard drive interface, specifically designed for networking, has only begun to be applied to hard disks as the operating system demands the speed of hard disks.

interface, which is primarily designed to improve the performance of the storage operating system, provide availability and scalability, and compatibility with serial ATA hard drives.

Interface is a new generation of interface standard tailored for ultrabooks, and the hard disk interface with extremely fast transfer speed has gradually become the mainstream.

The above are the types of hard disk interfaces.

The hard disk interface has IDE SATA SCAS (that is, the server hard disk) power supply mode, and the three are not the same, and the interface form is different.

It is divided into serial port SATA and parallel port IDE There is also server SCAS Now it is generally SATA hard disk interface.

IDE, SATA, and one is used on the server.

The hard disk interface is the connection between the hard disk and the host system, and is used to transfer data between the hard disk cache and the host memory. Different hard disk interfaces determine the connection speed between the hard disk and the computer, and in the whole system, the quality of the hard disk interface directly affects the speed of the program and the performance of the system. So do netizens know what classification there is for hard disk interfaces?

1. From an overall point of view, the hard disk interface is divided into IDE, SATA, SCSI, SAS and Fibre Channel five kinds, IDE interface hard disk is mostly used in household products, but also partially used in servers, SCSI interface hard disk is mainly used in the server market, and Fibre Channel is only used in high-end servers, which is expensive. SATA is mainly used in the household market, with SATA, SATA, and SATA, which are now the mainstream.

2. Under the category of IDE and SCSI, a variety of specific interface types can be distinguished, and each has different technical specifications and different transmission speeds, such as ATA100 and SATA; Both Ultra160 SCSI and Ultra320 SCSI represent a specific hard drive interface, and their speeds vary greatly.

3. CF (Compact Flash) interface is mainly used in small devices such as mobile, CF interface is manufactured according to ATA standards, but its interface is 50 pins instead of 68 pins, divided into two rows, each row of 25 pins.

4. The CE interface is an inch hard disk interface from Toshiba, which is similar to the CF interface.
