a dram of whisky ?
dram은 메모리의 일종이지만, 과거에는 전혀 다르게 사용되었다.
dram과 gill이 스코트랜드 위스키의 단위로 사용되다가 오래 전 법적으로 금지되었는데, 최근 다시 사용하려고 노력하는 모양이다.
예전에는 3.5 ml였지만, 지금은 25 ml나 35 ml로 쓰려고 한다니 딱 위스키 한잔에 해당되는 용량이다.

Abstract
Disk-oriented approaches to online storage are becoming increasingly problematic: they do not scale gracefully to meet the needs of large-scale Web applications, and improvements in disk capacity have far outstripped improvements in access latency and bandwidth. This paper argues for a new approach to datacenter storage called RAMCloud, where information is kept entirely in DRAM and large-scale systems are created by aggregating the main memories of thousands of commodity servers. We believe that RAMClouds can provide durable and available storage with 100-1000x the throughput of disk-based systems and 100-1000x lower access latency. The combination of low latency and large scale will enable a new breed of dataintensive applications.
