This is what I am starting to suspect. Maybe high peak QD's are occuring because the SSD is dealing with requests so quickly. Maybe that is why the average QD stays around the same.
I picked this up as well. Maybe I just had Photoshop open longer and it auto saved when I was monitoring the SSD. For MW2 I loaded a level, played the level, let the next level load and then closed it. I did the same on HDD and SSD so I have no idea why writes were so much higher.
Later today I am going to install a game on both HDD and SSD. That way I will know for sure that I am writting the exact amount of data to both HDD and SSD.
The monitoring is recording per process, but it seems TRIM instructions are being sent out all the time by the OS and maybe that is part of the reason that SSD in general is seeing a lot more writes.
The clear conclusion for me at this stage is that the vast majority of IOP read/ writes are done in less than a ms with SSD, which is obviously why a SSD feels so snappy and I'm not sure if raid could improve that. What I don't know is if max MB/s speeds would increase in a raid set up.
Comp, can you run a game on a raid array and show the results as I have shown on the last couple of posts?
