So your run of the mill SSD these days is like 500MB/s. Dual channel RAM @ 1600Mhz with 64bit bus is: 2 * 8bytes * 1 600 000 000 = 25.6GB/sec 500MB 1000x faste

500MB 1000x faster would be 500GB/sec or about 20x faster than standard RAM.
That puts the claim in perspective :)
- narrator 10y ago500GB/Sec. the network is going to have to do some work to catch up to those speeds. We're going to see big iron replacing clusters until networking catches up.
- 1024core 10y agoYou're talking throughput. They're talking latency.
- bluecalm 10y agoYeah, I had a blind spot here. It's just throughput is all that matters for things I am doing so it didn't occur to me "performance" claims might about latency. Thanks for pointing that out.
