I am a total newbie to FCPX and video editing, please take that into account...
I have a macbook air 2011 with a measly 120Gb and would like to edit 2 hours (246 GB) of Sony EX - 1 footage. (XDCAM MP4)- Because of a sale here in Germany I could get either a 120gb elgato thunderbolt SSD external drive (or its 24OGb cousin) for a rather cheap 99/199 €. Since my macbook does NOT support USB 3.0 and I would otherwise be stuck with USB 2.0 I reckoned it wouldn't harm to get a fast drive?
Do you think it makes sense to get one of those drives and use it as an external disk for importing the native material and editing? All I want to get is 20 minute of film out of the material (Not much of effects, just simple editing). Then again, will 240 G disk space be enough for editing 246 G of native material? (I suppose transcoding into Pro Res would create even more Gigs and going the Proxy Resolution route might harm the overall outcome?)
To cut a long story short, will the rather small 240 GB elgato ssd drive (or maybe even the 120 GB one) suffice for what I want to do (and make the editing experience nicer because of the speed) - or I am better of getting a slower USB 2.0 disk but with a larger 1TB capacity?
