I don't think the initial access time (latency) shall be included when speaking about peak bandwidth, otherwise it is not the peak bandwidth.
Peak bandwidth shall be considered with ideally infinite (large enough) payload to make latency negligible. When you have these two values, latency and peak bandwidth, you can estimate your (still theoretical, of course) performance given the transfer size.
The article uses the 240-320 MB/s peak bandwidth, and 110-130 ns latency for a comparison with the used external flash, which has latency in the us range and a peak bandwidth of 17 MB/s (arguably assuming using infinite payload, as 136.5/8 is about 17, i.e. without taking the initial setup time).
Still, even if you compare the actual speeds of a 1996 Pentium with the theoretical external flash speed values cited in the article, the consideration does not change: the external flash is much slower than what you could get even in 1996.
