I have a new PC on order, my first with a SSD drive. I also have a hybrid HDD/SSD. If I move the swap file and temp directory from the SSD C: drive to the hybrid D: drive, I should have more room on C: Accessing them on D: will probably be slower, but will Win7 use the processor cores/threads concurrency to regain some of that speed? I have 32G of RAM so I expect only a small number of RAM-intensive applications to cause swapping, correct? As for the temp directory, I don't know how much Win7 uses it and thus the need for SSD speed. I have the same question about the hibernate file, but I rarely hibernate my desktop and don't care much how long it takes. Lastly, the same question about C:\Documents and Settings or just C:\Users\USERNAME.
