Corsair SSD Help

Hi guys,

I have a corsair F40 hooked up to my Gigagbyte H55N-USB3 (media PC) and for some reason i am not getting full speeds.

I have the latest BIOS for my board and yet i still dont get full speeds i should. Can you run through all the noob mistakes i may have made? Or if anyone has any experience with these SSDs / motherboards that can help?

Thanks
 
If it's been in and running for a while check to see if TRIM is enabled.

Run Command Prompt as administrator and type fsutil behavior query disabledeletenotify.

If the message you get back is DisableDeleteNotify = 0 then you don't need to worry about that.

If it comes back with DisableDeleteNotify = 1 then type fsutil behavior set disabledeletenotify 0.

If you haven't had the drive in their long it could be that you're not far off the rated speeds and it just feels slow to you, which I think is impossible for a newer SSD.



 
Also make sure you disable defrag as this can slow the drive alot.

Try running ATTO benchmark, to give you a better idea of the "actual" speed.

Dunno wether it makes a difference or not but ccl tech guy told me to put it on ahci mode in bios

Yep, done that, yet still, the SSD should be running at Read 280MB/s, Write 270MB/s, but instead it is running at:

What sort of ahci drivers? You switched off of ide mode? Did you mess with the registry entries?

I just installed the lot off the disc it came with, here is the screenshot from the BIOS - Am i missing something obvious?

Also, i have litteraly just installed windows. I know i need to tweak defrag, indexing, system restore etc, but that couldn't cause the lack of speeds?

Ive been doing some reading, and people seem to be having issues on gigabyte boards, something about "JMicron ports" Did you try different sata ports? Move things around a bit, see if that helps. Also, are you missing any drivers for your chipset?

I dont think i am missing any drivers, but i will check.

Moving the ports around is my next port of call. I just wanted to be sure there was nothing else.

I will give that a try now, thanks for the help bud.

Try the intel ports first, they should be the ones to the rightmost. I'll keep searchin though, see what I can find.
 
Another question, did you switch it to AHCI before, or after the windows installation? If you install windows first, and then switch to AHCI it will really make some problems, because windows will skip installation of the ahci driver. If you set to ahci BEFORE you install your OS, the ahci driver will be enabled in the registry. Or at least this is the information i'm gathering.

*EDIT: You will never get advertised speeds, but your benchmarks are beyond the acceptable tolerance threshold for sure.
 
I tried this on another PC with my Intel 510 SSD, which performs fine and the results are the same. You think it could be a bad drive?

Its possible its a bad drive, it happens. Read my last reply about your windows install, it might lead us to that conclusion.
