The Curse of Areal Density | SNIA

Abstract

During the past half decade, the uninterrupted march of higher and higher areal densities has begun to encounter the unforgiving laws of physics. Where once the differences between the energies required write and read had not mattered one iota, the higher forces demanded by writes are putting pressure on a wide variety of I/O parameters that previously were thought to be inviolate for random access read/write storage devices. A new form of Whack A Mole has emerged in which point solutions for various problems are popping up faster than file systems designers can respond. Never mind that the real hobgoblin is licking his chops and preparing to claim more victims.
