Solid state hard disk is relative to the traditional mechanical hard disk in terms of operation on a call! Traditional mechanical hard drive reading method is the magnetic head fixed, disk high-speed rotation! And solid state hard disk is to use flash memory particles as a storage medium! Relative to traditional mechanical hard disk, solid state hard disk is thinner and lighter, running completely no noise, and because of the use of flash memory particles as a storage medium, reading speed is faster, generating a lower rate of fragmentation, the operation process is not afraid of bumps!

Depending on the flash memory particles used in the SSD, the service life is different! Today there are mainly SLC MLC TLC these three particles, the longest life is SLC, up to 100,000 times more than the full erase life! MLC about 5,000 to 10,000 times around the erase life! However, there's no need to get hung up on the erase life of flash particles! Take the least TLC for example, a 120G SSD, fully erased once is 120G! According to the 500 times fully erased is 60000G of data erasure! Even if you fully erase the disk once a day, it will take more than 1 year to use the bad! Today's solid state hard disk, basically used to install the operating system, data erasure is not high, normal use, a TLC particles of the solid state hard disk, can also maintain the normal use of about 3 years! There is no need to worry about the life expectancy of a solid state drive!
