What is the reading and writing speed of mechanical hard disk and solid state hard disk?

1, the average reading and writing speed of mechanical hard disk is 60-80M per second.

2. Between different brands and models of SSD, the average is about 150-300m/ s..

3, 5400 rpm notebook hard disk: 50-90MB per second.

4.7200 rpm desktop hard disk: 90- 190MB per second.

5. The reading and writing speed of solid state hard disk can reach 500 MB/s. ..

Extended data:

The difference 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. Solid-state hard disk is made of flash particles (memory, MP3, U disk and other storage media), so there are no mechanical parts inside the solid-state hard disk.

This will not affect the normal use even in the case of high-speed movement or even overturning and tilting, and minimize the possibility of data loss 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.
