Solid-state drives are actually designed to spread data around the drive evenly, which helps to spread out the wear effect - rather than one area of the drive seeing all the writes and getting worn down, the data and write operations are spread over the drive.Īssuming you use an operating system that supports TRIM - Windows 7+, Mac OS X 10.6.8+, or a Linux distribution released in the past three or four years (Linux kernel 2.6.28+) - you never need to overwrite or “wipe” your free sectors. The drive can simply read the data from whatever sectors it resides in. On a solid-state drive, there’s no mechanical movement. If a file’s data is spread out over the drive, the head will have to move around to read all the little pieces of the file, and this will take longer than reading the data from a single location on the drive. On a mechanical hard drive, defragmenting is beneficial because the drive’s head has to move over the magnetic platter to read the data. What’s more, you won’t see any speed improvements from defragmenting. The storage sectors on an SSD have a limited number of writes - often fewer writes on cheaper drives - and defragmenting will result in many more writes as your defragmenter moves files around. You shouldn’t defragment solid-state drives.
