But as an added bit of weirdness, it seems that ATTO benchmark is running like it's supposed to and reaching those promised 500 mb/s speeds. Is this just a problem with AS SSD's benchmark or should i actually be worried?

ive used roughly 80GB and nothing major xfered. unless gaming counts (all the data rewriting)
IDK, maybe gaming? Possibly just because it is such a low end SSD. Not sure. Make a thread.

I wanted to ask, is there any known issues involving P35 motherboards and SSD performances? Adquired recently an used SSD and even on a clean W7 x64 installation I wasn't able to make it run as it should. However, when i run the test from my old WD disk, the test look ok!

From my old W7 installation:

From a clean W7 installation:

thump_7833335hd-tune-desde-mismo.jpg

If my memory's right, my motherboard supports SATAII controller integrated in ICH9R.

The performance in the fresh W7 installation drive is really poor, system freezes every 10 seconds average... Any ideas?
Post a screenshot of AS SSD: (link)
  1. Open AS SSD
  2. Select your SSD in the top left drop down box
  3. If troubleshooting a SSD run the benchmark as well, if HDD do not run the benchmark.
  4. Click "File" at the top
  5. Click Screenshot > Save
  6. Upload to OCN in your post with the image insertion tool.

Nope, score is normal for your drive. It is a low end sandforce drive and can not handle incompressible data well. You need to test with ATTO to get advertised speeds.

Ooops, missed this post. Nah, it is normal. More info here: http://www.overclock.net/t/1179518/seans-ssd-buyers-guide-information-thread

I just got a 120 gig Vertex 3 for my Macbook Pro, and although I was able to get it into SATA III mode, im not able to get AHCI. This doesn't really bother me as TRIM still works and regardless it is much faster than my stock 5400 RPM drive... My question is, my results seem very low, but is this due to it being in IDE and not AHCI?

Actually TRIM will not work.

And the speeds are lower b/c it is in IDE as stated.

Ok, im glad to know the speeds are what should be expected from IDE, but I did a bunch of research all over the net to see if TRIM should work in IDE and the resounding answer I always came up with was yes. I don't have the links anymore (im sure I could find them) but people stated that TRIM wasn't initially supported on IDE but drivers were made to pass trim over IDE. Your the SSD guru so ill trust you over other random apple forum people, but as far as you know TRIM won't get passed to the SSD over IDE? I ran the CMD line to check if trim is on and it is on, being passed to the SSD or not, im not sure and I don't know how to tell.

Exactly, the keyword is: Drivers

Now do you have any IDE drivers that allow for TRIM to pass through to the SSD? The default Windows driver does not. If not then Windows is just sending the command, yet the driver is not sending properly it to the drive. (Window's test with CMD is just to see if Windows is sending the command, not if the SSD is actually receiving it.)

Shoot, yea I didn't download any special drivers.... Im not even sure where I would get them. Should I just try and update my drivers via Computer Management>Device Manager? Should I install intel rapid storage as well?

I tried to update via device manager, it is "up to date". But im sure I read somewhere there was a new driver that allowed for TRIM. Man, wish I saved that web page madsmiley.png
Also, I suppose a more important question, how important is it to try and get TRIM enabled? Its a Vertex 3, so it has garbage collection, although it is only used for taking notes in class and working on projects on campus (not heavy use, but not very much up time in order to allow garbage collection to do its thing...)

Hello again Sean! Here're the screenshots you asked for...

Test ran from the disk itself (clean W7 installation on SSD disk)

Test from another disk, my old WD Green 320GB:

Thanks!

I don't know where to get any IDE drivers that support TRIM myself. I am pretty sure you can't use the IRST driver either and will get an error upon trying to install.

Ehh...TRIM optimizes GC and reduced write amplification. It is a great thing to have, but imo it is not that important. You can run it for a while with out TRIM and it should be fine. If speeds dramatically drop after a few weeks-months then run a secure erase and you will be back at new speeds. If you can figure out a way to change to AHCI mode do it. You will get a little extra performance as well. smile.gif

I would make a system image. Then secure erase the SSD. (link) Then restore the image and benchmark again a few days later. Really odd performance drop...how much free space on the drive? Little free space on the drive could have been the issue.
