Do not put any VIDEO or IMAGES on your SSD - as SSD's are horrible at transferring compressed data. Keep video and images on your secondary HDD.
Only drives based on SandForce controllers suffer from this phenomenon. Drives using IndiLinx or Samsung controllers perform the same on compressed and uncompressed data. That puts the slightly higher price of Samsung drives in perspective. IndiLinx is a subsidiary of OCZ and they are just starting to make an impression in the market with this new controller. OCZ also makes many drives based on SandForce but I wouldn't be surprised to see them move their entire product line to IndiLinx eventually.
