Want to know what are the benefits of using solid state drives in notebooks?
First of all, we have to understand what a solid state drive is. (Recommended learning: web front-end video tutorial)
Solid State Disk (SSD for short) now mainly refers to semiconductor storage drives based on NAND FLASH (and non-flash memory) , because it is considered to be able to replace traditional mechanical hard drives, we translated it as solid-state hard drives. It is mainly composed of a control unit and a storage unit (Flash chip). Simply put, it is a hard drive made of an array of solid-state electronic memory chips. The interface specifications and definitions, functions and usage of solid-state drives are almost the same as ordinary hard drives. The shape and size are basically the same as an ordinary 2.5-inch hard drive.
Benefits of using solid state drives in notebooks
1. Fast speed. Because solid-state drives do not have the mechanical structure of ordinary hard drives, the system can complete I/O (input/output) operations on any storage unit in less than 1ms. Moreover, solid-state drives do not have the seeking problems of mechanical hard drives.
According to relevant media tests:
Under a laptop with the same configuration, when running large image processing software, you can clearly feel that the SSD solid state drive is saving or opening. files are faster.
The data access time is generally less than 0.2ms, while ordinary hard disks are generally greater than 15ms. The ability to read data is above 100M/s, and the highest one can currently reach 300M/s; the writing speed is also above 80M/s, and a good SSD can reach above 200M/s. The fastest read and write speed of a 7200 rpm hard drive with a SATA interface does not exceed 150M/s, and the actual test speed is around 70M/s.
2. Durable and shockproof. Because all flash memory chips are used, there are no mechanical parts inside the SSD solid state drive. This will not affect normal use even when moving at high speed or even with flipping and tilting. Moreover, if the laptop is accidentally dropped or It can minimize the possibility of data loss when colliding with hard objects.
3. No noise. SSD solid state drive is very quiet when working, without any noise. Thanks to the lack of mechanical parts and the small size of the flash memory chip, which generates less heat and dissipates heat quickly, SSD solid-state drives have no mechanical motors and fans, so their operating noise level is 0 decibels.
4. Light weight. SSD solid state drives are 20-30 grams lighter than conventional 1.8-inch hard drives, but don’t underestimate these weights. In portable mobile products such as laptops and satellite locators, smaller weight is conducive to portability. In addition, the weight reduction also makes it possible for notebooks to be equipped with multiple SSD solid state drives.
5. Low power consumption. Long battery life The power consumption of SSD is only 0.5W in standby mode and
