Seems like you now get 2.1 gigbytes/sec sequential read from a cheap consumer SSD today...
Not many consumer drives give more than 500-600 MB/s (SATA3 limit) yet. There are only a couple that I know of that reach 2000 MB/s, like Samsung's SM951, and they're generally a fair bit more expensive than what most consumers tend to buy (but at about $1 / GB, still affordable for businesses certainly).
