In the rental of the Hong Kong server, the type and storage space of the disk are one of the factors that must be considered. At present, there are many types of disk type used in Hong Kong servers, and more and more disk storage spaces should be selected with caution. So what are the types of Hong Kong server hard disk disk?
1.SSD hard disk
SSD hard disk refers to a solid -state hard drive. The main advantages of the SSD hard disk are manifested in good stability, fast storage and reading speed, no disk fragmentation, and less noise. Low -capacity SSD solid -state hard disks are small and lighter than the same capacity hard disk, but this advantage gradually weakens with the increase in capacity. At the same time, compared with the traditional hard disk, SSD solid -state hard disk has a lot stronger, and the data security protection ability is also very strong.
2.HDD hard disk
The most basic computer storage drive of the HDD hard disk is also the hard disk used by traditional servers. According to the interface classification, the HDD disk can be divided into FATA, SATA, SCSI, SAS and other categories. And the HDD hard disk capacity space is also relatively large, with 160G, 500G, 1TB of hard disk space. For example, most of the American servers use HDD hard disks, and can reach 1TB of storage space.
3.SAN disk
The SAN storage area network adopts mesh -shaped channel technology and connects the storage array and server through the FC switch to establish a regional network dedicated to data storage. SAN storage is a dedicated network specifically for storage. It is a special network that is independent of the TCP/IP network. The common SAN includes two types: FC-SAN and IP-SAN.
4.raid disk
The RAID disk arrays are combined by many cheap disks into a large -capacity disk group. It uses individual disks to provide the bonus effect produced by data, thereby improving the performance of the entire disk system. It includes three forms: external disk array cabinets, internal disk array cards, and using software simulation. Since the RAID disk can improve the data transmission rate and provide fault -tolerant function, many servers also use RAID disk storage data.
