Bought MBP mainly for video editing right now. But household has many PCs. I bought a firewire 800 capable 2 TB drive for editing the HD video. It is formatted NTFS right now and I could get that Paragon util to let OSX read and write NTFS. Or i could format it Mac native and that could I guess have a performance gain? Any thoughts? The downside of going Mac native is any PCs will need to have software to let them mount it.
