Odd PM/Brawl Performance Issues after Switching to SSD

I've been playing Project M online ever since 3.0 came out without issues. It's been flawless other than the occasional desync issues online. I recently purchased a PNR XLR8 256GB SSD[http://www.newegg.com/Product/Product.aspx?Item=N82E16820178456] and installed Win 7 on it. Now when I try to play PM, every couple of seconds or so, I lose frames. The game stutters, it shows 45 fps for a second, then goes back to 60. I'm guessing that is the average because it definitely feels like it goes down to zero for a split second. This problem is amplified significantly when playing over netplay.
I have isolated the problem to the SSD. Originally I transferred the files from my HDD to the SSD. I have tried running dolphin from the HDD (including editing the registry so that dolphin used the Dolphin emulator folder on my HDD rather than SSD) and from the SSD and it makes no difference. I even went as far as disconnecting the HDD, reinstalling windows on the SSD, recreating PM again and nothing changed. I've tried every permutation of dolphin settings.
As far as other games, I tried Mario Sunshine and it was fine, although it is a GC game so probably not the best test. The same stuttering happens in Brawl and Mario Kart Wii.
I haven't had any other issues with the SSD. OS loads fast and I played through the second half of AC4 on it.
Specs:
OS: Win 7 x64
CPU: i7-2600k Quad-Core 3.6ghz
Ram: 8gb
GPU: GTX 570

Thanks for getting this far...any ideas?

You'll want to clarify if this is a problem in the latest revisions or just in the dc-netplay branch. The netplay branch is not supported, so unless the community has come up with a solution there isn't anything the devs can do to help.

Some SSDs are really bad at certain operations; I had an old SSD that really struggled with loading large files.

Is source code for dc-netplay around anymore? And why was it dropped?

It's still around, it's just that no one is working on it, and it has core changes that break compatibility with master by quite a bit.

Whoops good point. I've seen no difference on 4.0, 4.0-648, or 4.0-652.

So I take it I'm screwed?

If you're old builds have problems and the new builds have problems and they didn't use to, then I don't see how we can help other than make random guesses as to what kind of hardware issue you're having. You could try installing another harddrive and putting your ISO there.

I've just been using the old HDD which I still have no problem with. It just sucks since I can't use the SSD for PM it turns me off of using it entirely. And kinda worried I'll have the same issue on other SSDs if I shell out another $100.

I use an SSD with no issues; but I also used an older SSD that had severe issues. Older SDDs, the first couple generations, suck with big files.
