I shoulda said for editing I don't really notice it. I run windows, chrome and my most frequently used programs/games off of it and all I really notice is the boot times, especially with fast boot on my msi board it's basically instantaneous to turn my system on. Even then it's more of a showpiece than something useful or worth spending money on when it could be spent on more ram or a better cpu.
I read this on toms hardware and it basically is what my thoughts were when using the ssd explained a little better.
with video editing please keep in mind that reliability of the drive is way more important than the speed of it.
Keep in mind also that 2 high end HDDs can feed an OC'd i7 enough compressed data (h/x.264) to keep it at full load if you are doing heavy loads. In short, you do not 'need' SSD performance to have an excellent editing experience. That being said, I have done one project on my SSDs, and OMG!!! the instant seek time of the SSDs really make things snappy when randomly picking a spot to start playing from!!! But other than that extra quick responsiveness I did not see much other improvement in actual use for editing and rendering speeds because compressed data is rather CPU heavy. If you start editing raw, uncompressed (or low compressed) footage (like lagarith), then you will see a huge performance boost because there is less load on the CPU, and more load on the drives, so for that workflow SSDs would make more sense... but you would need some nice big drives.
