Flash seeks nicely - but a wider interface than SD might be
preferable for custom hardware. CF is very straightforward to
interface with. As for off-the-shelf, SATA compensates with high
link speed. SATA SSD seems to cost same as USB memory sticks.

USB is widely available, but still a serial bus, so only a single
request to a single memory stick per host controller is in flight at
any one time. (Even with 8 USB ports it's still one controller.)

64x CF suggests custom hardware.

If considering custom hardware it would be interesting to talk to
semiconductor sales people, since 2 TB worth of flash chips is a
decent size order even if it would be just one-off. Flash storage
cost could come way down, trading for hardware development time and
manufacturing cost of course.

How will lookup work? #4 is sadly empty. Can lookup be parallelized?
If not so much then seek time could indeed justify custom flash based
storage (and also lookup?) hardware.
