Hi, Daniel! I've been thinking about buying a Dell Alienware laptop for Scarlet's post production(CS5.5 editing&grading). Does a configuration like this work?



PROCESSOR Intel® Core™ i7 2760QM 2.4GHz (3.5GHz w/Turbo Boost, 6MB Cache)
OPERATING SYSTEM Genuine Windows® 7 Home Premium, 64bit
MEMORY 16GB Dual Channel DDR3 at 1600MHz (4DIMMS)
VIDEO CARD Dual 2GB GDDR5 NVIDIA® GeForce® GTX 580M – NVIDIA® SLI® Enabled
HARD DRIVE 500GB 7200RPM SATA 3Gb/s

should I get an external raid0? raid1? raid5?
