[SOLVED] SSD has extremely slow write times.

I'm not sure what has caused the problem but it started a few months ago, I thought that the issue was with the USB because that's where I was trying to copy large files from. However it's actually the Hard drive, a PNC XLR8 240GB drive. I ran crystal disk info and it said everything was fine.

But when I ran a benchmark test, the problems are obvious. Write speeds that are so slow they make dial-up look fast.

Does anyone know what would cause this? I haven't made any changes to the computer that I can think of.
Do I need to give it up and buy a new drive?
Thanks.
 
Solution
Overprovisioning means - part of the drive is left unallocated.
Execute these commands. This will make 10GB at the end of the drive unallocated ( also size of C: gets reduced by this amount).
diskpart
list disk
select disk 0
list partition
select partition 3
(select 512MB partition, make sure you have selected correct partition)​
delete partition override
select partition 2
(select 222GB partition)​
shrink desired=10240
exit

The files seem to change constantly, here are 2 SS taken 30 sec apart.

The last SS is during a slowdown, while trying to make a copy of a several GB folder. You can see the progress bar for that at 5.3 MB/Sec.

I'm not sure how to set up over provisioning, I used the default settings for formatting I believe.

I'm also not sure about the Disk 0 or system Reserved partition, I didn't set those up intentionally.
