Under the hood: Facebook’s cold storage system
"...since we were using low-end commodity storage that was by no means enterprise-quality."If Facebook (and I believe it's similar with other big players like Google and Amazon) are not using "enterprise grade" hardware (because it doesn't make economic sense at scale), who is? And more importantly, why? Why do "enterprise grade" products even exist if the largest and most deep-pocketed corporations don't find them to be good value propositions?
