![]() If the SSD needs to overwrite data to a page with data, the SSD must first erase the block corresponding to the page to make room for new data to be written to this location, then all the blocks in the block Copy page to a new block, and then erase the block to be written. SSD reads and writes are based on Page, and erase is based on Block. SSD mainly consists of four parts: Die, Plane, Block, and Page. To put it simply, Trim is an SSD optimization function that solves the problem of speed reduction after SSD use.įirst of all, let's take a look at the process of reading, writing and erasing data of SSD. The SSD controller waits until the host starts the delete and rewrite operations, and then executes the secure erase operation. When the data of the relevant page can be overwritten, the operating system will issue a TRIM instruction to the SSD. It will tell the SATA interface instructions of the NAND flash solid-state storage device which data to erase. Trim is a new technology developed by Microsoft in conjunction with major SSD manufacturers. What is the Trim command? What effect does it have on SSD? Whether computer users want to enable or disable Trim, this article will discuss one by one. I must mention a concept here that is the Trim command, because it plays a vital role in the high performance of the SSD. Many computer users are also willing to choose SSD when upgrading their own hardware. Although there are subtle differences between different SSDs, the overall low energy consumption and high performance characteristics of SSD have been recognized by the majority of users. ![]() Compared with HDD, SSD has become popular among computer users because of its fast writing speed, low reading delay. Solid-state hard drive is called SSD by many people now. ![]()
