TRIM is an essential feature for an SSD to keep it on top performance and helps the drive to last much longer. Here's how to make sure the feature is enabled on Windows 10. Besides getting a speedy processor and as much RAM as you can afford, a Solid State Drive (SSD) also plays a very important role in making your PC fast. However, an SSD will stay on it best performance and last longer only if it's properly maintained. TRIM is an ATA command set that was originally designed for the purpose of keeping a Solid State Drive at its optimal performance throughout its lifespan. The TRIM feature allows Windows 10, or any supported operating system, to notify an SSD which blocks of data are no longer in use and can be safely wiped out to be writable again. Having this operation done ahead of time improves performance, as the drive won't have to spend time erasing a particular block when space is needed to store new data, ensuring the SSD reaches its advertised lifespan.
