Probably latency is much more important than bandwidth for this application. The latency of these cards is typically 100 microseconds for a random read (this is for a fast M2 card; secure digital cards and SATA are much slower). At 3GHz that's 300,000 cycles. Intel's XPoint (now branded Optane) promise much better latency, as low as 9 microseconds, but even this is 27,000 cycles. With a GPU and 9 microseconds you can do an awful lot of computation.

Hello,
a math table lookup on a SSD micro card ?: why not ...
ok but the reading speed of those are something like 90 megs per second on a 'class 10' card,
on the other hand there are those new ssd that can be plugged into a PCI express 4x slot (if you have one on your pc),

the reading speed is 3500 megabytes per second. That's another animal, the drawback is of course the price and your electricity bill. ;-). and you have 1 TB of space to put tables. the price is about 650 us dollars.
