That is because Magician uses your system memory like a ram disk to speed up access. Its cool. I saw 9000MBs on my 840 pros using it.

I found that the ssd is so fast for most work which is random that I saw no performance difference.
At one time I had a problem which I suspect was magician related so I turned it off.
For large sequential transfers, the ability of the ssd nand chips to accept continuous updates is perhaps limited.
Bulk storage of large files such as video's is better done on a hard drive anyway.
Be skeptical of ssd benchmarks.
They are done with apps that push the SSD to it's maximum using queue lengths of 30 or so.
Most desktop users will do one or two things at a time, so they will see queue lengths of one or two.
What really counts is the response times, particularly for small random I/O. That is what the os does mostly.
For that, the response times of current SSD's are remarkably similar. And quick. They will be 50X faster than a hard drive.
In sequential operations, they will be 2x faster than a hard drive, perhaps 3x if you have a sata3 interface.
Larger SSD's are preferable. They have more nand chips that can be accessed in parallel. Sort of an internal raid-0 if you will.
Also, a SSD will slow down as it approaches full. That is because it will have a harder time finding free nand blocks to do an update without a read/write operation.

I no longer run Magician either. It was causing issues with my OS. It works well most of the time though.
