Advantages and disadvantages of solid state drives
the only drawback is that an independent power supply is needed to protect data security. It is a kind of high-performance memory, and its service life is very long.
The application methods can be divided into two types: SSD hard disk and SSD hard disk array. Following the design of traditional hard drives, volumes can be set and managed by file system tools of most operating systems, and industry-standard PCI and FC interfaces are provided to connect hosts or servers. Solid state hard disk based on DRAM: DRAM is used as storage medium, and its application range is narrow at present. The biggest advantage of this kind of SSD solid state disk is that it can be moved, and the data protection is not controlled by power supply, so it can adapt to various environments, but its service life is not high, so it is suitable for individual users.
#Advantages and disadvantages of solid state drives serial
Compared with the traditional mechanical hard disk, it has the advantages of low power consumption, shock resistance, high stability, low temperature resistance and so on.įlash-based solid state hard disk (IDE FLASH DISK and Serial ATA Flash Disk): use FLASH chip as storage medium, and their appearance can be made into a variety of shapes, such as notebook hard disk, micro-hard disk, memory card, flash drive and so on. Using the traditional NAND Flash characteristics, block writing and erasure are used to read and write, so the efficiency of reading and writing depends very much on the development of flash memory technology. SSD generally refers to the use of flash memory chips composed of SSD solid state hard drive, is the use of FLASH flash memory particles as a storage unit, no longer use the traditional mechanical storage methods, use simulation to simulate the traditional hard disk access methods and sectors, etc., you can also simply understand that solid state disk is a "large USB disk" with hard disk interface (SATA/ATA, etc.), what is different is that there is no mechanical structure.
