This is a Snip of mine.
To the right of that is a Snip of the Samsung Toolbox pdf.

I OP'ed my Samsung after installing the OS.
When I did it the amount I OP was listed at 11.9GB which is almost 10%.

It will take a few minutes to complete but not real long.
It has to move some files around to make the unallocated space but it will make the space and then make it unallocated as in my SNIP which is what you want.

RMA'ing it may be the best bet.
Make sure you do over provisioning on the new one at least.
If you already did this I missed it in the thread.
I am looking at both of these and they say that everything can be wiped out.
I am not concerned, because I have a full backup, but is that likely?
There is no new Samsung SSD firmware.

I only had about 50GB on the SSD and I had back up images if needed.

Follow kbradys suggestion for now with the AS-SSD.

I wasn't trying to interrupt.

Also, for the length of time you have had the SSD and how much data you have on it, I don't believe over provisioning is what caused your problem. I'm not 100% sure, but I have quite a few months on mine, without over provisioning and it still runs the same as the day I got it.
I think I misunderstood and ran the test: Looks as bad as the others.

I just needed to see the info in the top left corner, but it doesn't hurt to run the test. The write speed and access time is pretty far out of whack, as we already know. It's almost as if trim or garbage collection, whichever applies here, isn't working properly. I'm still thinking it is an internal SSD problem. Nothing we have done has really had any positive effect on the write performance.

Something you could try, although it seems as if RMA'ing is your best bet, is doing a secure erase and reinstalling windows and running a test on it after you get drivers on it. You don't need any fancy customization, just a clean install, then drivers, then test. If the numbers are still crap, we know it is the drive, if not, it is something else entirely. I understand if you don't want to do this though, just being thorough!

I tried to see if TRIM was on there and was told to open HDtune and look there, but there is no option for that.

Could it be that the backup image I transferred from the hdd is causing all this, even though it was fine at the beginning?

Trim is something enabled in Win 7, but some SSD's have a housekeeping function like Garbage Collection, or something similar, that keeps everything in tip-top shape. It looks like before it writes, it is having to find a suitable place to write to, if that makes any sense. Also, I am NOT an expert on SSD's, I only understand so much from using and reading about them. If I am way off on how they work, I hope someone will correct me.

Kelly,

If I do a clean install, do I just go into Disc Management and delete partitions to make them Unallocated space?

You should do a Secure Erase from the Samsung Magician software and I believe that will take care of all of that. Backup anything you feel you can't do without first. Then install Windows normally. Like I said, it doesn't have to be fancy, just a test to see if you get crappy numbers after a clean install and drivers are loaded.

Okay, I still have a full copy on the HDD as well as a backup of this drive of an Acronis image.

Thanks a ton.

Here is what my Samsung tested at earlier tonight......
Well, Kerry, I finally was able ( I think) to do the install.

Here is the latest Crystal Disc pic.

Should I still return the drive?

Thanks for all your help.
