Though 1,375MB/s worth of disk speed might seem extravagant, applications like 4K RAW video need to squeeze every byte. Luckily, you'll get all of that with LaCie's 1TB Little Big Disk with Thunderbolt 2 packing two 500GB SSDs, now available for $1,300. If even that isn't enough -- and you happen to have a new Mac Pro with six Thunderbolt 2 ports -- you can put two in parallel for an eye-watering 2.5GB/s (capital 'B'). That'll let you transfer 1TB of footage in under seven minutes or run over 10 streams of 14-bit RAW 4K video simultaneously. Overkill? Sure, but we don't need a 949 HP car, either.
