The continuous reading of solid state drives is generally around 500MB/second, and the continuous writing is generally around 500MB/second.
Advantages of Solid State Drive SSD:
Data storage speed: Under the same computer configuration, the reading speed of Jinsu Solid State Drive can basically be About 500MB/s, while mechanical hard drives are within 150MB/s.
Such a speed difference will significantly improve the computer's response speed.
Shockproof and drop-proof: Traditional hard drives (ATA or SATA) are disk-type, and data is stored in disk sectors. Solid state drives are made of flash memory particles.
Therefore, there are no mechanical parts inside the Jinsu Solid State Drive SSD, so even if it moves at high speed or even with flipping and tilting, it will not affect normal use, especially when used in notebooks.
Power consumption: Also because there are fewer mechanical parts, the power consumption of solid-state drives is also better than traditional mechanical hard drives.
Weight: Solid-state drives are lighter in weight, weighing dozens of grams lighter than regular 2.5-inch hard drives.
Noise: Since solid-state drives have no mechanical parts and flash memory chips, they have the characteristics of low heat generation and fast heat dissipation. They also have no mechanical motors and fans, and are silent when working, with a noise value of 0 decibels. , which makes traditional mechanical hard drives much inferior.
The reasons why solid-state drives get slower with use:
Solid-state drives get slower with use. This has a lot to do with the working principle of solid-state drives. .
Solid state drives use flash memory as a storage medium, and flash memory has a characteristic: it must be erased before data can be written again. This is different from mechanical hard drives, which can directly overwrite and write data.
When we buy a new solid-state drive, the NAND flash memory has been erased in advance, so the data can be written directly without completing the data clearing step. At this time, the data writing speed is very fast.
As time goes by, there is less and less unused storage space in the SSD. In many cases, the data in the flash memory must be erased and then written again, so its performance will decrease significantly.
In order to solve this problem, Microsoft and SSD manufacturers have made great efforts, such as Trim, garbage collection mechanism, etc.
Of course this is only one of the reasons. As a new thing, SSD has many Users still don’t understand its “habits”, so it is obviously not suitable to transfer the habits developed in the era of mechanical hard disks to SSD.
