The benefits of solid-state hard disk and the difference between solid-state hard disk and ordinary hard disk

What's the difference between solid-state hard disk and ordinary hard disk? What are the benefits of SSD? This article will answer you one by one.

Start quickly

Solid-state hard disk does not have the process of motor accelerating rotation, and the startup speed is faster.

Fast random reading

Solid-state hard disk does not need a magnetic head, so the reading speed is faster and the reading delay is minimum.

A relatively fixed reading time

The addressing time of SSD is independent of the data storage location, so disk fragmentation will not affect the reading time.

Writing speed is extremely fast

The writing speed of solid-state hard disk based on DRAM is extremely fast.

No noise

Solid-state hard disk has no mechanical motor and fan, and the noise value is 0 dB when working.

Low energy consumption and low heat

Low-capacity SSD based on flash memory has low energy consumption and low calorific value, but high-end or large-capacity products have high energy consumption.

Not afraid of collision, shock and vibration.

Solid-state hard disk has no mechanical moving parts, so there will be no mechanical failure, and it is not afraid of collision, impact and vibration.

Wider operating temperature range

Most SSDs can work at-10~70 degrees Celsius, and some industrial SSDs can also work at -40~85 degrees Celsius or even higher.

Small size, light weight

Low-capacity SSDs are smaller and lighter than those with the same capacity. Up to 256GB, SSD is still lighter than ordinary HDD with the same capacity.
