What's the difference between a solid state drive and a removable hard drive

The difference between a solid state drive and a removable hard disk is mainly in the storage principle, speed, durability, size and weight, noise and usage scenarios.

1, the principle of storage: solid state drives use flash memory chips as a storage medium, while mobile hard drives use traditional disk storage technology, using magnetic materials to record data.

2, speed: solid state drives have faster read and write speeds, generally up to hundreds of megabytes per second, while the read speed of mobile hard disk is generally in the tens of megabytes per second or so.

3, durability: solid state drives are less affected by vibration and collision due to the lack of mechanical parts, making them more durable compared to mobile hard drives.

4. Size and weight: SSDs are usually lighter and thinner than mobile hard drives.

5, Noise: Since mobile hard disk needs mechanical parts to run, it will make some noise, while solid state hard disk has no mechanical movement, so it is less noisy.

6, the use of the scene: mobile hard disk can be plugged in or unplugged at any time, it is very convenient, applicable to a variety of devices between the data transfer and backup. Solid state drives have higher read/write speeds and durability, and are suitable for scenarios that require frequent reading and writing of large amounts of data.
