Don't think it is from any external interfering, but same here - I haven't seen an answer as to why it's like that so it's just speculation. I've done different tests on mine with most everything stopped, still the same, and every shot of someone elses I've seen is almost an identical pattern, or very similar.
Your access times are low.
Check for chipset driver updates, set your Power Options to High Performance.
Is your SSD Write caching enabled?
Have you seen this OCZ forum thread:
OCZ Sandforce (Agility2/Vertex2) expected Benchmarks and General Info
From the second post:
Here is the thing, if you hammer the driver with say enough writes that the drive would under normal use/see in 7 days within a few hrs, the drive will slow down for 7 days, maybe longer. It does this to protect the nand life. So your guys seeing a 50% drop may actually see 30% which is the normal drop, then a further 20% because at some stage they have hammered the drive and then not realised its going to take 5 days or longer for the speed to creep back up. Also remember this write quantity slowdown is further impacted by how you use the drive after you have hammered it.
So take this as an example:
1 you run a few benches and fill the drive with incompressible data,...you do this a few times
2 you run As-SSD a few times and on each run the performance drops lower and lower.
3 you panic thinking the drive is broke
4 you then note its just slowed down quite a bit so continue benching to see if it has started to speed up
5 this benching is actually delaying the drive recovering
6 you note the drive has stayed dog slow....so continue with 4 to 6 AS-SSd runs per day hoping or looking for a drive speed increase
7 the drive stays dog slow
8 you post on the forum that the drive is somehow broken
What you see here is an end user actually inducing the slowdown and not allowing the drive to recover...and its really very easy for this to happen.
SF have told me a drive with incompressible data will bench sequentially a LOT SLOWER than a drive with a mix or more compressible data...so just by using AS-SSD you are actually limiting the drives speed.Also speed is directly linked to what has been written to the drive and what is being written. This seem linked to TRIM speed also where GC reallocates blocks that have had compressible data written to them faster than blocks with incompressible data.
Maybe you should wait a week before trying the AS SSD benchmark again.

I read the article . It's old news the new G2 models don't have that problem , In fact with the Intel Tool Box ,You can clean your drive everyday if you want.
This what Intel has to say about it.http://downloadcenter.intel.com/Deta...eng&iid=dc_rssReadMe File.doc, Read word Doc.

Please don't link direct download files.
Link the site that has the download file link.
It will give everyone the chance to see the source.
had the drive for about a year and the controller said it has written 3 terabytes so far. no drop in performance since I bought it. not the best but it loads Call Of Duty maps like crazy, I have to wait at least 15 seconds for a game to start and it beats all my buddies raids set ups.
Here's my score. I do not have AHCI capability on my chipset (ICH7) and I'm trying to get the drive out to take to work to update the firmware...but, still not too shabby.
Thank you to all who've helped me with being green on SSDs, I now find myself trying to figure out why my work PC is so much slower than my home PC...:)
OCZ Vertex2 120GB:
Figures look to be in the ballpark as others.
smarty, did you test it before with 1.11 firmware? Any improvements with 1.23?
I'm wondering if it's worth my hassle to upgrade to 1.23...thx.
