Today's mainstream cash registers on the market use SSD solid state drives. People who don't know about electronic products will have a question. What is the difference between SSDs and ordinary mechanical hard drives? Today Xiaobian made an article on the choice of cash register hard disk for customers to choose.
the difference:
(1) The read and write speed of the solid state hard disk is very fast, and the flash memory is used as the storage medium, and the reading speed is relatively faster than the mechanical hard disk. Solid state drives do not use heads, and the seek time is almost zero. SSDs can continue to read and write faster than 500MB/s, which is much larger than 100MB/s for ordinary mechanical hard drives.
(2) There is no magnetic head inside the solid state hard disk, nor is it a CD, so it can also achieve the anti-seismic effect. Moreover, the solid state hard disk does not have a motor and a fan in the mechanical hard disk, and the noise value during operation is almost 0 dB. No noise and a wide operating temperature range. There are no mechanical moving parts inside, no mechanical failure, and no collision, shock or vibration.
(3) Life limit. Today's SSDs have a fixed number of read and write times, which is why many people are criticized for their short life, but their read and write times are not very significant compared to the life of ordinary hard drives.
Suggestion: If you buy the cash register and start to use the cash register, do not download the software. In the case of video, we still recommend that you use 32G or 64G solid state drive, fast reading and writing ability, quiet, light, and larger working temperature range. , anti-seismic, anti-fall, etc., so, for the efficiency of our cash register, you can try to buy, you can also choose a large capacity, stable performance of 500G mechanical hard disk.
