Solid State Drives, also known as SSDs, are hard drives made up of a solid-state electronic chip array. They consist of control units and storage units (FLASH chips, DRAM chips). Although the interface and definition of SSDs are similar to those of ordinary hard drives, they have different application ranges. SSDs have a wider range of uses, including navigation devices, in-car systems, medical systems, military industries, and network terminals, among others. SSDs have various interface types, such as SFF-8639, SATA-2, PCI-E, and SATA-3.
SSD drives use flash memory as the storage medium, so their read/write speeds are much faster than mechanical hard drives. SSDs do not have a read/write head, so there is no need for "seeking," and the time is greatly reduced to "0." When using SSD drives, we can feel their fast continuous write speed.
SSDs have strong shock resistance, as they do not use "disks" like traditional hard drives, where data is stored in the disk sector. Instead, SSDs use "flash memory particles" as the storage space, which are made up of multiple media. Therefore, we can see that SSDs do not have any mechanical components, so data is not lost in the event of a collision. Therefore, SSD drives have an excellent advantage in terms of "shock resistance."
SSDs have low power consumption and long service life.
SSDs do not have fans or motors internally, so they do not make any noise when starting up. Furthermore, because there are no moving parts inside, the amount of heat generated is low, so there is no possibility of machine failure. Of course, their heat dissipation rate is also very fast.
Ordinary hard drives usually start up within the range of 5 degrees Celsius to 54 degrees Celsius, but SSDs are different. They can operate within the range of minus 10 degrees Celsius to 70 degrees Celsius.
SSDs are small in size and lightweight, and they are about 30g lighter than common portable hard drives, making them easy to carry.
SSDs have fast startup speeds, especially when playing games. They not only enhance gaming performance, but also accelerate the computer's startup process.
