I'm looking to buy an external hard drive to use as a HD scratch disc. Ive read through the forums and watched a few videos off site of what is recommended for video editing concerning hard drive options. Please give me some good options from best option to least best. Some say FW800 is better for video editing and some say USB3 is. Im confused after reading that USB 3 is faster but technically FW800 is better for video editing from the videos I've watched. I also hear that LaCie is the best for use for video editing. I am using a Mac mini with the latest OSX, it has a Samsung 256GB 840 Pro SSD boot drive and a 1TB 5400 media drive and 16gb DDR3 RAM. I film using a Canon Vixia HF G20 HD camcorder. For now I use a old western digital 640gb Slim HD USB2.0. Definitely not cutting it for my workflow. After I save on the WD, I admittedly upload the final completed video to a online cloud service for storage and my social media page. My current online Cloud storage holds 250ish videos so this should give you an idea of how big a HD I would need to save the editing videos on the HD I want to purchase and then deleting the raw footage and only keeping the final production. To reiterate I want to keep my final videos on the external hard drive as well for awhile until I remove them to either store on the cloud service and/or burn my videos on a blu-ray as a data disc. Please recommend me a better option for workflow and efficiency. I'm looking to purchase a HD soon. The sooner the better. Thanks your input and help. I appreciate it. PS I hear LaCie is good for video editing as a HD scratch disc and I like how it has its own power on/off switch and separate power outlet source. Says one the website specifically good for programs such as FCPX correct me if I'm wrong.
