Can SAS hard drives be converted to SATA hard drives? What is the method?

OK. The physical interface of the two is the same, and the SAS host can be compatible with SATA device, and the reverse connection is OK.

SAS interface.

Compatible with SATA devices, but SATA interface.

SAS interfaces are generally only available on server motherboards, and some servers may use relatively inexpensive SATA hard disks when considering the cost of construction.

Instead of SAS hard disk, if there is a SAS interface, you can safely connect to ordinary SATA equipment.

The interface is compatible with SATA devices, 2However, the SATA interface is not compatible with SAS devices, 3In layman's terms, the SATA standard is a sub-standard of the SAS standard, SAS contains more instructions, and more control and detection technologies, and the interface is generally only available on the server motherboard, 5

When considering the cost of some servers, they may use relatively cheap SATA hard disks instead of SAS hard disks, 6If there is a SAS interface, you can safely connect to ordinary SATA devices.

You can go to the computer store to buy the transfer interface, but it is not recommended! Not cost-effective! If you want to use the contents, you can buy a hard disk holder, and the good ones are less than 200.

I want to know what you want to do first, a 15000 rpm, if you don't need to do it urgently, you don't need to do it, but if you make a system, you can use both of them, but you have to do something else, maybe you can't say. But I still want to know what you want to do.

Looking at the shape of the SAS interface, if it is the same as the SATA port, the hard disk with the SAS interface can be used for the SATA interface. In addition, there is a SAS to SATA cable for docking, but the SATA interface is not compatible with SAS devices.

The reasons are as follows: 1. Hard disks with SAS interfaces, i.e., SCSI hard disks, are designed to improve the efficiency, availability and scalability of the storage system, and provide backward compatibility with SATA hard disks.

2. Because the cost of the SAS hard disk interface is usually only available on the server motherboard, some server motherboards can use the relatively cheap SATA hard disk interface instead of the SAS hard disk interface due to the construction cost.

First, the subject is different.

1. SAS: Serial connection SCSI, which is a new generation of SCSI technology.

2. SATA: also known as serial port hard disk, is the trend of PC hard disk in the future, which has basically replaced the traditional PATA hard disk.

3. SSD: that is, solid-state electronic storage array hard disk.

Second, the characteristics are different.

1. SAS: Each SAS port can connect up to 16,256 external devices, and SAS adopts direct point-to-point serial transmission mode, with a transmission rate of up to 3Gbps.

2. SATA: The storage node is composed of the memory control interface MCI and the SATA hard disk controller.

3. SSD: The main body is actually a PCB board, and the most basic accessories on this PCB board are the control chip, cache chip and flash memory chip used to store data.

Third, the advantages are different.

1. SAS: It is a new interface developed after the parallel SCSI interface. This interface is designed to improve the performance, availability, and expandability of the storage system, and to provide compatibility with SATA hard drives.

2. SATA: It can effectively filter out the noise from the normal signal, and the good noise filtering ability makes SATA only need to use low voltage operation.

3. SSD: control data writing, error correction, erasure, etc., which can realize performance optimization, data encryption and write protection functions, data security erasure mode, self-destruct function, etc.
