My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Hardware Past As Performance Prologue. The worldwide ASP 18 months ago was ~$300USD , so the average performance in the deployed fleet can be represented by a $300 device from mid-2019.

HotStorage 2019. Both abstractions must be implemented in a way that is efficient using existing hardware. The hardware perspective. At the hardware level we want to able to move data into, out of , and around memory, without consideration for persistence and reference lifetimes. Application requirements. Object spaces.
