![]() ![]() Overcoming SSDs performance issueĪ lot of drive manufacturers add extra storage to each drive that is unavailable to the user to prevent Solid-State Drives from degrading performance. The only caveat is that the entire process takes time, and repeating the process on many blocks dramatically reduces speeds, affecting performance. The solution to this problem is a write operation that loads the data inside a block into the cache, modifies its content by adding the new data, and then writes pages back to the block. The problem is that SSDs cannot use the leftover space in a block to write new data directly because it would actually destroy any data already on it. NAND flash memory example by Dmitry Nosachev ![]() If the blocks are not empty, then the Solid-State Drive must delete the data inside them before information can be written again, which can add significant delay affecting performance.Īs you continue to store data and storage fills up, the drive will begin to run out of blocks, and because Solid-State Drives can only write data in pages of 4KB or 8KB inside of a 256KB block, you end with blocks that are not completely filled. TRIM is a feature used by an operating system to command the drive to find and delete any data on blocks that make up a deleted file, so later on, the drive can quickly fill them up again with new data. The process of filling an empty block with information is the fastest way to write to the storage, which is the main reason operating systems, such as Windows 10 or Windows 11, include support for TRIM. When you’re working with a file and ready to save it, the Solid-State Drive finds the necessary empty blocks and writes your data for long-term storage. ![]() Although they accomplish the same thing, they both store data. Solid-state drives work differently than traditional hard drives. ![]()
