“在过去的五年里,闪存从一类仅仅只是有前途的、在数据中心的地位尚不明确的加速设备,成长成了一类成型的企业级数据存储关键构件。它向统治地位的跃迁,是随着它在消费者世界的迅速扩增以及随后的“容量经济(the volume economics)”而起的。固态硬盘(SSD)让闪存以为兼容而优化了的形式存在——仅需用固态硬盘取代传统硬盘,便可获得理论上更佳的性能。然而固态硬盘所使用的NAND Flash存储器的属性,与它们通常所取代的硬盘中的磁介质属性有着巨大的不同。虽然固态硬盘已经渗透到了各个应用领域,可是业界设计充分利用闪存介质微妙特性的存储系统的步伐,才刚刚开始。随着它渐渐摆脱兼容性的束缚,性能、可靠性和价格上重大的改进 完全可能 。”

Icon"In the past five years, flash memory has progressed from a promising accelerator, whose place in the data center was still uncertain, to an established enterprise component for storing performance-critical data. It's rise to prominence followed its proliferation in the consumer world and the volume economics that followed. With SSDs, flash arrived in a form optimized for compatibility - just replace a hard drive with an SSD for radically better performance. But the properties of the NAND flash memory used by SSDs differ significantly from those of the magnetic media in the hard drives they often displace. While SSDs have become more pervasive in a variety of uses, the industry has only just started to design storage systems that embrace the nuances of flash memory. As it escapes the confines of compatibility, significant improvements in performance, reliability, and cost are possible."
