The 1GB/Second figure isn't impressive at all (or at least, shouldn't be the headline).
The impressive part is that this is a 2^20 field (RS(million, half-million)). Most RS-encoders/decoders are much smaller, either 2^8 or even smaller (CD ROMs are RS(28, 24). Satellite is around RS(256, xxx) or so).
Because this is a matrix multiplication operation fundamentally, the order is O(n^2) or so in terms of scaling. Sooooo yeah, quadratically difficult to calculate as the data per block grows.

Because of the computational difficulty of large RS encoders/decoders, today seems to be focused on Turbo codes or LDPC codes instead of RS. 2^20 is probably the largest RS code I've ever heard of, very impressive that it's actually at 'practical speeds' (1 GB/sec should be practical albeit a bit slow)
Larger and larger block sizes are important. LDPC probably is the more practical methodology today, though I admit that I'm ignorant about them. Still cool to see someone try to push Reed Solomon to such an absurdly huge size though.

And I do believe this is limited to half-million parity blocks, not 1 million parity.
