For some years now Solid State Drives (SSDs), based on flash memory, have existed as an alternative to conventional hard disks. Deciding to deploy them depends on the requirements made of storage media reliability, system reaction speed, system efficiency and last but not least of course, it also depends on the costs. This document is dedicated to frequently asked questions (FAQ) about the topic SSD. It deals with technical aspects of conventional SSDs, PCIe-SSDs and DOM (Disk On Module), paying particular attention to lifespan, but also provides information about the optimal use of SSDs in the PRIMERGY server family.
