I'm trying to decide weather it makes more sense to get the maximum internal flash storage on a nMP or purchase an external device. £640 seems like a good price for 1Tb and it seems like a simple solution for fast storage. The machine will be mainly used for video editing. Most projects are not larger than 300Gb and it seems that I will I longer need to transcode formats like Red R3D before editing, so this might even go down. So maybe 1Tb will be enough for active jobs, the OS and applications. When jobs are finished they are archive to single drives anyway. I be interested to know anyones thoughts and what they decided to do? 1TB PCIe-based flash storage [+ £640.00] External: PROMISE Pegasus J2 512GB (2 x 256GB) SSD Thunderbolt Hard Drive £599.00 PROMISE Pegasus2 R4 8TB (4 x 2TB) Thunderbolt 2 RAID System £1,249.00 Little Big Disk Thunderbolt 2 1Tb £??
