How much free space should i leave on ssd

When an SSD has a lot of free space, it has a lot of empty blocks. If your device includes a solid-state drive SSD , you probably noticed that as it fills up the performance slows down dramatically. The short answer is yes, solid-state drives are faster than traditional rotating platter hard drives.

A full SSD makes load balancing difficult. So it will have increased wear in a smaller area of the disk. Windows provides no further detail, but freeing up space allowed the troubleshooters to start. Microsoft does not disclose a specific amount of free space you should keep. Windows will only partially defragment the drive, and it will grow increasingly fragmented over time. However, this just applies to mechanical hard drives that need defragmentation, and not the solid-state drives generally found in more modern PCs.

Solid-state drives traditionally needed a large chunk of available free space, too. This overprovisioning actually means the solid state drive has more memory than it exposes to you. When an SSD has a lot of free space, it has a lot of empty blocks. When an SSD has little free space, it has a lot of partially filled blocks.

When you go to write a file, it will have to read the partially filled block into its cache, modify the partially-filled block with the new data, and then write it back to the hard drive.

This will need to happen with every block the file must be written to. In other words, writing to an empty block is fairly quick, but writing to a partially-filled block involves reading the partially-filled block, modifying its value, and then writing it back.

Repeat this many, many times for each file you write to the drive as the file will likely consume many blocks. This one is fairly obvious. Solid-state drives are smaller and much more expensive per-gigabyte than mechanical hard drives are. However, they make up for it with reduced power consumption, less noise, and increased speed.

Ideal files to store on your solid-state drives include your operating system files, programs, games, and other files that must be accessed frequently and quickly.
