In general, the temperature of hard disk is generally higher than room temperature 10-20 degrees, which has little to do with the size of hard disk.
Summer is different from winter, the highest temperature in summer can reach 60-70 degrees, and the temperature of SCSI hard disk is higher, which will seriously burn your hands. Generally, the normal working temperature of IDE hard disk is about 30-50 degrees, and SATA is within the normal range of 50-60 degrees.
Solid state hard disk (SSD)
Solid-state hard disk is a hard disk composed of solid-state electronic memory chip array, which is composed of control unit and storage unit (FLASH chip and DRAM chip). Solid-state hard disk is exactly the same as ordinary hard disk in terms of interface, function and usage, and the product shape and size are also exactly the same as 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.
The working temperature range of the chip is very wide, including commercial products (0~70℃) and industrial products (-40~85℃). Although the cost is high, it is gradually spreading to DIY market. Because solid-state hard disk technology is different from traditional hard disk technology, there are many emerging memory manufacturers. Manufacturers only need to buy NAND memory and cooperate with appropriate control chips to manufacture solid-state hard disks. SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface and SFF-8639 interface are widely used in the new generation of solid state drives.
With the rapid development of Internet, people's demand for data and information storage is increasing. Now many storage manufacturers have launched their own portable solid state drives, and more mobile solid state drives supporting Type-C interface and solid state drives supporting fingerprint identification have been launched.
