SSD (Solid State Drive) is a non-volatile memory built on solid state architecture. Unlike a HDD, an SSD has no moving parts which gives it advantages such as faster reading and writing data, while a traditional hard disk drive consists of a spinning disk with a read/write head on a mechanical arm called an actuator.
The Life Span of an SSD
Life span depends on storage types of SSD drives. But, simply put, the more storage cells an SSD owns, the longer it will work.
Life span Forecast Formula for SSDs:
(Write cycles x Capacity) / (SSD Factor x Data Per Year)
The SSD factor specifies the rate of the real amount of data to the actual data written. For the calculation, one chooses a high value of 5. In addition, the amount of data that is written on the drive per year is estimated. If an estimation is difficult, then you can choose a value between 1,500 and 2,000GB.
