SSD performance degradation

I bought a new PC about 4 weeks ago and installed a 120gb OCZ SSD. Start up times from pressing the power button to having everything loaded into windows was about 15 seconds and shut down time was about 10.

Couldn't be happier.

Now, 1 month on with 40 - 35gb free on the SSD I'm getting boot up times of around 40 seconds and shut down of about 20.

Now don't get me wrong, these times aren't a bother. My last computer was so slow I could have turned a corpse on quicker. Performance wise the programs installed on the SSD seem to be running as they were when I first installed them. But is the longer boot up time just down to more stuff being installed on the drive?

Mike.
 
Oh right. I never realised. I thought it was something that just worked as you did.

I don't log off but it has been left alone, still on, for a few hours over the past few days.
 
Yes windows 7 and it is one of these

Although it looks different (checked on their website and they said that the model in that picture has been discontinued, specs on the box were exactly the same though)

Anyways. Here are some screenshots.

Assuming it's a Vertex 2(E), an ATTO benchmark would be more appropriate.

Have you been doing some heavy benchmarking with the drive ? (those will degrade drive performance much quicker then the normal usage patterns)
If not, then run the mentioned benchmarks (imo AS SSD is probably the most relevant one) and post the results, or google for becnhes of the same drive and compare with your results. I would not expect the performance to degrade this quickly, for example it is ~ half year since I flashed to new FW on my drives and since then I completely didn't care about them (not even consciously giving them time for garbage collection other then keeping the PC on while going away as I would do with a non-SSD drive) and of course since I am running RAID I never used trim. At the end I get slightly worse write access time and seq speeds and about 1.35x worse random write speeds, but hardly anything that could contribute to boot time increase from 15 -> 40s. Are you sure your problem isn't windows becoming bloated over time ?
 
Sorry to hijack the thread, but the bit about giving them time, does this work if the computer is off? Or does it need to be logged off the user and just sitting at login?

Hm, your write speeds are definitely off (I suspect heavy benchmarking is the cause as this probably shouldn't happen with normal usage)

Maybe you want to do the same as recommended in this thread http://forums.overclockers.co.uk/showthread.php?t=18194868

@Tomcat825 - with computer off - you mean without using power ? I hardly think it will work without power ;-)

Until today I'd never run any kind of benchmark on that drive. So you can rule that out ;)

I just checked and I never updated the firmware on the ssd. So i'm doing that now and I'll test it again when Its all done.
 
The quick fix is to clone the drive (using Acronis True Image 2011 in "disk mode" preserves alignment), secure erase it and restore the image. Otherwise, to get optimal performance you need to:

- Be using the best SATA drivers for your controller (e.g. Intel RST 10).
- Be running in AHCI mode.
- Have a fresh SSD install (i.e. NOT one that was cloned from an HDD).
- Not run benchmarks often.
- Leave the PC logged off for a few hours a week.

Alright, thanks for that.
