This article describes the features and applications of HP enterprise class solid-state drives (SSDs) and IO accelerators. A subsequent article will detail the differences in these solid-state storage devices based on performance, latency, lifetime writes, and expected life at 100% writes.

HP solid-state storage devices are based on NAND flash memory, which is the predominant solid-state storage technology. Before describing the features and applications of these devices, we must explain a few important characteristics of NAND flash memory.

If you are unfamiliar with NAND architecture, read the technology brief “Solid state storage technology for ProLiant servers” here.
