Hi community,

So I've known this for a while and now it's really starting to bother me.
My SSD is nothing like what it used to be when I first bought it.

I've tried using SSD Tweaker to make sure all the necessities are in place (e.g. TRIM is still enabled).
I have a fear it's the fact I also have 2 500gb hard drives in RAID 0 also in place and because I only have one HDD controller the RAID configurations is slowing down the SSD (as it's not in AHCI), but this is just my guess.

Any help greatly appreciated, thank you :)

There's no such thing as too old hardwawre for W10. You probably just didn't get the right drivers. And 10 is a vastly superiour OS in all accounts, including speed...

Run trimcheck to see if TRIM is working properly. ALso, have you by any chance filled the drive? 10+% should always be left free.
What i can tell you for sure is that it has nothing to do with your RAID config. If the controller is set to RAID mode, drives that are connected to it and not in an array work in AHCI as expected normaly.

SSD is 65% filled, can be seen in top left of the attached image. 145/223GB used.



I just tried that application and got this message:
'Test file created and deleted, and continuation data saved.
Do what needs to be done to activate the SSD's TRIM functionality, and run this program again.'

This tells me TRIM isn't enabled but I googled a bit and used this link:
http://mywindowshub.com/check-enable-disable-ssd-trim-support-windows-7-windows-8-1/
and after running the cmd I get 0 (which tells me it is enabled).

Also, good to know it does run in AHCI, I've never completely filled the drive but i have been left before with only about 30/40gb space.

You need to run trimcheck once, wait for 30s-1min and then run it again.

Ahhhh, sorry. I left it for a bit. It said: TRIM appears to be NOT WORKING.
Tried restarting PC (as it said it may need that) and still the same message.

Not sure what to make of it now. Whether TRIM is on or not.

Is your computer ever left idle?

I have a Sandisk something OEM in my work computer; they typically hibernate after 15 minutes of non-use. I R/W to the disk with quite intensive workloads at times, and it had really slowed down to a crawl. TRIM is enabled, but apparently the Sandisk drives only carry out trim operations when the drive is left idle for ~15-30 minutes or so. I changed the power settings, then logged out and left the computer overnight, and there was quite a marked disk performance improvement the next day.

Run teh command from here to enable trim: http://mywindowshub.com/check-enable-disable-ssd-trim-support-windows-7-windows-8-1/
restart, then test again with trimcheck(with anotehr restart).
Is your Windoews up to date andalso are your SATA drivers updated?

I don't use it for anything intensive but I definitely leave it alone for periods longer than 15-30 mins quite regularly. The PC doesn't go into any 'idle' state per-say though, it doesn't sleep or hibernate, just has a screensaver.



Yes, as stated before, mine already shows 0, so TRIM is already enabled according to this guide. It's just TRIM check that says it isn't.
All my drivers are up to date.

Well at this point i would suggest that you upgrade to W10. While it may have been upgraded in the meantime, W7 was conceived whithout SSD support in mind. You will not have any such issues with 10, and, as far as i know, one can still install 10 with a 7 key, ever if the offer expired oficially.

Hah, been down that road. Never again mate. I hit way too many blue screens, by day 2 I went back to Windows 7. I think my hardware just too old for Windows 10.
Thank you for the advice though, I guess I'll just live with the speed as it is for a year until I upgrade.

Just gave this a shot, unfortunately because of the RAID array the SSD is interpreted as a SCSI connection and as a result SanDisk Dashboard does not recognise the SSD (link for reference).


Unfortunately then something must have gone wrong with the drivers during the upgrade. A fresh install probably wouldn't have given me the same problems.

Yeah, that too. My recommendation stands, man.
