The older versions of these cards can read faster than a RAID-10 of
80x15k RPM SAS drives, based on our tests from a couple yeas ago. Writes
aren't *quite* as fast, but still much better than even a large RAID array.
They ain't cheap, though. You can expect to pay around $15k USD per TB,
I believe. There are other similar products from other vendors which may
have different cost/performance ratios, but I can only vouch for stuff
I've personally tested.
Our adventure with these cards was a presentation at Postgres Open in
2011. Slides are here:
