Bw/latency comparison

It's worth noting there's a disconnect between the JEDEC standard latencies and what's actually available. It lists the DDR4 latencies at around 13-14ns but 10ns latency kits can be bought without paying a significant premium[1].

Latency often does increase with new generations of RAM.

But remember to compensate latency cycle counts with the faster cycles of higher speed RAM. Often the absolute time in nanoseconds hasn't changed as much as the cycle count numbers make it seem.

It is a bit of a trade-off. For desktops and other personal devices you usually want lower latency. For servers and HPC you often want higher bandwidth.

Isn't the biggest problem with SSD latency generally that paralell reading / writing is not used within software that was optimized for hard disk?
