Why...
If you run a couple of 240Gb's then:
- one full card can be downloaded while you're flying and filling the other.
- you've only got 240Gb to lose in the air if you crash'n burn
If you just run a single 480Gb then:
- you're stuck on the ground until it's been downloaded and reformated
- If your
I2 is lost, you've lost all your footage ('cuase you didn't download half of it
)
So, the 240Gb is worth a little money hit for the convenience - you can keep flying more easily than with the single 480GB.
And, if two 240GBs don't quite keep you flying and you need a third, then it'll only be £1.5K instead of £2K, then it's actually a few hundred squid cheaper and you're laughing
Of course, if you're feeling flush and have a couple of grand to spare, then get two 480GB's
