This article will explain in detail the difference between solid state disk and mobile hard disk. The content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Mobile hard disk refers to the hard disk memory that uses USB interface, can be plugged in or unplugged at any time, and is compact and easy to carry, while solid-state hard disk refers to the hard disk made of solid-state electronic storage chip array, which is generally used to assemble desktop computers.

Advantages of solid state hard disk

Fast reading and writing speed: using flash memory as the storage medium, the reading speed is faster than the mechanical hard disk. Solid-state drives do not use heads, and the seek time is almost zero. The speed of continuous writing is so amazing that most SSD manufacturers will claim that their SSDs continue to read and write faster than 500MB/s! The speed of SSDs is not only reflected in continuous reading and writing, random read and write speed is the ultimate meaning of SSDs, which is most directly reflected in the vast majority of daily operations. It is also associated with extremely low access times, the most common 7200-speed mechanical hard drives typically have seek times of 12-14 milliseconds, while solid-state drives can easily reach 0.1 milliseconds or less. [5]

Shock resistance: traditional hard drives are disk-type, and data is stored in disk sectors. The solid-state hard drive is made of flash memory particles (that is, mp3, U disk and other storage media), so there are no mechanical parts inside the SSD solid-state disk, so that normal use will not be affected even in the case of high-speed movement or even accompanied by flip tilt, and the possibility of data loss can be minimized in the event of collision and shock. Compared with traditional hard drives, solid state drives have an absolute advantage. [5]

Low power consumption: solid state drives consume less power than traditional hard drives.

No noise: the solid state drive has no mechanical motor and fan, and the noise value is 0 decibels when working. Flash-based solid state drives have lower energy consumption and heat generation in working state (but higher energy consumption for high-end or high-capacity products). There are no mechanical moving parts inside, no mechanical failure will occur, and there is no fear of collision, shock and vibration. Because the solid-state hard disk uses flash memory chip without mechanical parts, it has the characteristics of low heat generation, fast heat dissipation and so on. [5]

Wide operating temperature range: a typical hard drive can only work in the range of 5 to 55 degrees Celsius. Most solid state drives work at-10 to 70 degrees Celsius. Solid state hard disk is smaller and lighter than mechanical hard disk of the same capacity. The interface specification, definition, function and usage of solid state hard disk are the same as those of ordinary hard disk, and the appearance and size of solid state hard disk are the same as those of ordinary hard disk. The chip operates in a wide temperature range (- 40-85 degrees Celsius).

Lightweight: solid state drives are lighter in weight, 20-30 grams lighter than conventional 1.8-inch hard drives.
