"Here is what I have done so far to try and sort the problem out......

1) updated my bios to F5 and changed the settings from IDE to AHCI for the port the SSD is connected to (this was a pain in the arse with regular BSOD's on boot, but I eventually got it working)

Fail button, necessary!


wow thats horribly slow ssd man. Thats a Sata2 mobo?

hope you didn kill the drive doing all those checks and benches. And gotta be a better way to do it rather than Norton Ghost..
Personally, Im a HUGE fan of "when in doubt, save and reload."

P.S.
And for goodness' sake, stop benchmarking the drive every couple of hours. In case creating the OP space in Samsung Magician didn't mark the blocks as clear, create a new partition with the OP space, do a quick format (to trigger TRIM) and delete the new partition. Leave your PC idle for a couple of hours so the garbage collection can do its thing.

eek!! i didnt realise it was such a bad thing to benchmark / test it that often.
but surely, if you're problem solving and you're making changes, you need to test after each change to see if you've fixed it or not?

and i'll give your suggestion a go later on today smile.gif

Perhaps you should try a clean install of windows 8 on the SSD just as a troubleshooting step to see if it's a hardware or software issue you are having.. you can always re ghost the ssd afterwards..

unfortunately the original HDD is no longer around sadsmiley.gif

I agree that a fresh install would probably yield great results (presuming the drive isn't buggered) but am really really reluctant to go down that route.
this is had been win 7 or earlier, i'd have done a repair reinstall as a half way try, but win 8 is an utter ball ache for doing that kind of thing! mad.gif

lol smile.gif

yes it is, this is actually what i've got (from the manual).....

Storage Interface

South Bridge:
- 1 x IDE connector supporting ATA-133/100/66/33 and up to 2 IDE devices
- 6 x SATA 3Gb/s connectors (SATA2_0, SATA2_1, SATA2_2, SATA2_3,
SATA2_4, SATA2_5) supporting up to 6 SATA 3Gb/s devices
- Support for SATA RAID 0, RAID 1, RAID 5, RAID 10, and JBOD

GIGABYTE SATA2 chip:
- 2 x SATA 3Gb/s connectors (GSATA2_0, GSATA2_1) supporting up to
2 SATA 3Gb/s devices
- Support for SATA RAID 0, RAID 1, and JBOD


I've got the SB SATA ports set to IDE for a sata DVD-RW and the data Seagate SATA HDD
i've then got the SSD connected to the GB sata ports and set to ahci


and the only reason i use ghost is i've used it for many years now and it's always worked and i trust it. smile.gif

why RMA? There is nothing wrong...kookoo.gif
the drive just needs to be plugged into the AMD SATA 2 port and the SATA mode set to AHCI.

Should've mentioned this earlier. The first advice you would have received is to connect the SSD to the AMD ports.

Yes, you test. Unfortunately, each full run of AS-SSD writes 5GB of data to your drive, around 4GB of which is random so you don't want to run the tests too close together.

Since you're on Gigabyte SATA, my earlier suggestion of formatting to TRIM probably wouldn't have any effect as the Gigabyte SATA controller is probably too old to support TRIM.

Here are the steps I'd recommend you take:
  1. Connect SSD to AMD SATA2 ports.
  2. Create image of SSD using Acronis/Ghost/whatever else you might use and save to HDD.
  3. Secure erase SSD.
  4. Restore from the image back to the SSD.

right, quick update. smile.gif

I've moved the drives around and now have the SSD sat on a AMD port set to AHCI.
I've then got the Seagate and the DVD-RW also sat on the AMD ports but set to IDE.

there was also a firmware update for SSD via Magician which i installed.

the numbers are looking much better than when i started but are still some way off AndyM95's numbers (post #2)
I'll prob give the image off, secure erase, restore this weekend.


I've also got a side question about the page file which may or may not be affecting the speed of the drive.
with the 2 drives I have (240gb ssd and 500gb sata2) and 5gb RAM on a win 8 64bit OS, what size paging file (if any) should I have?
