What are the advantages of SSD and traditional HDD?

Comparison of advantages and disadvantages between traditional hard disk and solid state hard disk;

1, shock resistance and fall resistance: At present, traditional hard disks are disk-type, and data is stored in disk sectors. Solid-state hard disk is made of flash particles (that is, existing memory, MP3, U disk and other storage media), so there are no mechanical parts in SSD solid-state hard disk, even if it moves at high speed or even tilts, it will not affect its normal use, and it will minimize the possibility of data loss in the event of collision and vibration. Compared with traditional hard disks, hard disks have 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 traditional HDD.

3. Power consumption: The power consumption of SSD is also better than that of traditional 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. Traditional hard disks are much inferior.

6. Price: At present, the price of 80G Intel SSD on the market is around 4,000 yuan. And this price is enough to buy several traditional hard disks with the capacity of 1TB.

7. Capacity: At present, the maximum capacity of SSD is only 256G, which is far from the traditional HDD's TB capacity.

8. Service life: SLC has only 6,543.8+10,000 reading and writing life, while low-cost MLC has only 6,543.8+10,000 reading and writing life; Compared with traditional hard disk, it has no advantage.
