1. explanation of solid-state hard disk: solid-state hard disk, also known as solid-state disk, is a hard disk made of solid-state electronic memory chip array, which consists of control unit and storage unit. The specification, definition, function and usage of the interface are the same as those of the ordinary hard disk, and the shape and size of the product are also the same as those of the ordinary hard disk. Widely used in military, vehicle, industrial control, video monitoring, network monitoring, network terminals, electric power, medical care, aviation, navigation equipment and other fields.
2. Classification of SSD: The storage medium of SSD is divided into flash memory (flash memory chip) and DRAM. The working temperature range of the chip is very wide, and the commercial products are 0 ~ 70℃; Product specification -40~85℃. Because solid-state hard disk technology is different from traditional hard disk technology, there are many emerging memory manufacturers. SATA-2 interface, SATA-3 interface, SAS interface and? MSATA interface, PCI-E interface, etc. ?
3. Advantages of 3.SSD: Flash memory is used as storage medium, and the reading speed is faster than that of mechanical hard disk. Solid state hard disk does not need a magnetic head, and the seek time is almost zero. The continuous writing speed is amazing, and most SSD manufacturers will claim that their SSD continuous reading and writing speed exceeds 500 MB/s! The speed of SSD is not only reflected in continuous reading and writing, but also the ultimate meaning of SSD, which is directly reflected in most daily operations. Associated with this is extremely low access time. The most common seek time of 7200 rpm mechanical hard disk is 12- 14 ms, while solid state hard disk can easily reach 0. 1 ms or even lower. ?
