I should note not all SSD's are the same speed wise. The inexpensive PNY 120 SSD I bought may actually be slower then a totl HDD:

My HDD was a WD Black 7600rpm 2TB - so close in speed to the 1TB WDD Blue shown above. Note the PNY 120GB CS1311 speed. I probably should have - and may down the road move to a larger faster SSD. Although I have to say the boot times have dropped significantly, even with the 120GB.
But I believe this is what has caused the improved SQ with the PNY SSD vs the WD HDD:
Power demands on the SATA MB bus orders of magnitude less then the WD HDD. Less power supply load means less PS noise for both the drive and the MB/CPU. Not to mention the lack of motor vibration, read head servo noise modulation, ambient noise, etc...
What is interesting in this test - the older generation PNY CS2 211 240GB (373MB/S) )and 480GB (403MB/S) significantly outperform the newer generation PNY CS1311 480GB (210MB/S) and 120GB (96MB/S).
