SSD drives are increasingly popular for PC gaming boxes. With the recent move to motherboard mounted SSD drives, Windows is now faster to boot and games load faster.
SSD drives need some minor maintenance. The disk optimizer in Windows 10 can TRIM SSD drives properly which is one of the many reasons to upgrade immediately, Earlier versions of Windows are not able to TRIM SSD properly. Historically users had to rely on vendor supplied tools to maintain the SSD. Windows 10 can handle that natively.
The TRIM command simply tells the SSD which blocks the operating system is not using so that it can make them available for use with new data. This way the SSD is properly in sync with NTFS.
By default Windows runs the optimizer weekly. This is plenty to keep SSD and hard disks running fine.
