Are you using a SSD or a HDD?
I've seen instances where Trim has been stopped after certain Windows 10 updates. This results in a SSD not being recognized. Windows 8/8.1 and Windows 10 have a built in optimizer for ssd's it's called Trim. Windows is supposed to detect a ssd and activate it. To determine if Trim is activated please do the following.
This needs to be run from the Elevated Command Prompt using an Administrator account.
Click/tap on the Search icon (magnifying glass) in the Taskbar and type cmd.
You will see Command Prompt under Best match, right click on Command Prompt and select Run as administrator.
Copy and paste the following command in the Command Prompt followed by pressing Enter.
fsutil behavior query DisableDeleteNotify
If it returns a 0 then Trim is active, if it returns a 1 copy and paste the command below followed by pressing Enter.
fsutil behavior set disablenotify 0
