superiority
Solid state drives are easy to install and carry. Remove the optical drive from the notebook, and Xiaobai can install it himself. Low-capacity solid-state hard disk, low energy consumption in working state. When the notebook falls to the ground and the SSD is smashed, the possibility of data loss will be less.

Comparison of advantages and disadvantages between mechanical hard disk and solid state hard disk
1, earthquake resistance and fall resistance: the mechanical hard disk is disk type, and the data is stored in disk sectors. SSD is made of flash particles (i.e. memory, MP3, U disk and other storage media), so there are no mechanical parts inside SSD, even if it moves at high speed or even falls over, it will not affect normal use, and the possibility of data loss can be minimized in the case of collision and vibration. Compared with mechanical hard disk, hard disk has absolute advantages.
2. Data storage speed: According to the evaluation data of PConline evaluation room, the performance of SSD is more than 2 times higher than that of mechanical HDD.
3. Power consumption: The power consumption of SSD is also lower than that of mechanical HDD.
4. Weight: SSD is lighter, 20-30g lighter than conventional 1.8 inch HDD.
5. Noise: Because the solid-state hardware belongs to no mechanical parts and flash memory chips, it has the characteristics of small heat generation and fast heat dissipation, no mechanical motor and fan, and the working noise value is 0 dB. The mechanical hard disk is much inferior.
6. Price: Up to now, (2014/1/23), 128Gb SSD is about 450. 1Tb mechanical hard disk price is about 360. Solid-state hard disk is more expensive than mechanical hard disk, and its cost performance is lower.
7. Capacity: At present, the maximum capacity of SSD is 4t3.5 inches.
8. Service life: SLC has only 6,543.8+10,000 times of reading and writing life, while low-cost MLC has only 6,543.8+10,000 times of reading and writing life. Therefore, compared with solid-state hard disks, mechanical hard disks have a longer life.
