Samsung SSD vs. Sandisk

Do me a favor........if you have AS SSD installed already, open it up. You don't have to run it, just open it up and make sure the Samsung SSD is selected. Then take a snippet and post it here.....it should look something like this.

Attachment 231786

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.

Bring up Crystal Disk Mark, select the drive you want to test from the drop down box (your image is showing C: drive currently) I usually test 2 or 3 passes @ 1000MB ( your image is showing 5 passes at 1000MB) and when you have it set the way you want, click the "All" green box and wait for it to get done.

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.

Paul:)

Better.......run the AS SSD and ATTO benchmarks like you did before and post the results please.
