Hi. I'm in a profession where we produce massive 3D files, sometimes in video format, which need to be on my computer for demo purposes. Almost all the MB Pros I've had in the last 5-6 years have slowed down considerably after just 9-10 months of use (and all the "defrag" software are basically useless). My worry is that the MBA will in fact be worse for wear after some time if the SSD disk had a lot being written to it, and then deleted week after week? Thanks for any tips/advice.
