What are the benefits of notebook SSD?

Brief introduction of solid state hard disk

Solid state hard disk (SSD) now mainly refers to semiconductor storage drives based on NAND FLASH (and non-FLASH). Because we want to replace the traditional mechanical hard disk, we translate it into solid state hard disk. It is mainly composed of a control unit and a storage unit (Flash chip). Simply put, it is a hard disk made of a solid-state electronic memory chip array. The interface specification, definition, function and usage of solid-state hard disk are almost the same as those of ordinary hard disk, and the shape and size are basically the same as those of ordinary 2.5-inch hard disk.

At the beginning of its birth, due to the high cost of flash memory chips, the capacity of SSD is far from its traditional hard disk, so it can be said that it has not really entered the practical stage. And the price is unbearable for ordinary people. Recently, the cost of flash memory chips has been declining, and the technology is also constantly improving. The larger the SSD capacity, the cheaper the price. Nowadays, the growth rate of players using SSD is amazing, and there is a trend to replace traditional mechanical hard disks in the high-end hardware market.

Seek time+delay time constitutes the average access time of hard disk, which affects the related performance of hard disk. At present, the average access time of SATA hard disks we test is generally above 15 ms, but SSD has almost no concept of access time. In the test software, the average storage time of SSD is often

Benefits of using solid-state hard disk in notebook

1. Come on

Because the solid-state hard disk has no mechanical structure of ordinary hard disk, the system can complete I/O (input/output) operation on any storage unit within 1 ms, and the solid-state hard disk does not have the seek problem of mechanical hard disk. According to relevant media tests, when running large-scale image processing software, it is obvious that SSD solid state drives are faster when saving or opening files.

Its data access time is generally less than 0.2ms, while the ordinary hard disk is generally longer than 15 ms, and its data reading ability is above 100M/s, which can reach 300 m/s at present. The writing speed is also above 80M/s, and a good SSD can reach above 200m/s. The fastest reading and writing speed of 7200 rpm hard disk with SATA interface is less than 150M/s, and the real testing speed is about 70m/s..

2. Durable and shockproof

Because all flash memory chips are used, SSD solid state hard disk has no mechanical parts, so even if it moves at high speed or even falls over, it will not affect normal use, and the possibility of data loss can be minimized when the notebook computer accidentally falls or collides with hard objects.

3. No noise

SSD solid state drives are very quiet and have no noise. Thanks to the characteristics of no mechanical parts, small flash memory chip, low calorific value and fast heat dissipation, SSD solid state hard disk has a working noise value of 0 dB because it has no mechanical motor and fan.

4. Lightweight

SSD solid state drives are 20-30g lighter than traditional 1.8 inch hard drives, so don't underestimate these weights. In portable products such as notebook computers and satellite locators, smaller weight is beneficial to portability. In addition, the weight reduction also enables the notebook to carry multiple SSD solid state drives.

5. Low power consumption

Long-life SSD consumes only 0.5W when standby, while
