Part 1 of this series laid out the basics of nand flash SSD with part II discussing endurance and performance. This part looks at SSD options for virtual servers, vdi or virtual desktop as well as storage for physical server environments, your usage and configuration criteria will have a bearing on what type of SSD solution is best for you.
Solid-state devices (SSDs) are data storage memory (Figure 1) mediums that utilize semiconductor based memoires as opposed to magnetic media found in hard disk drives (HDDs) or magnetic tape. Semiconductor memories include ultra fast volatile dynamic random access memory (DRAM) commonly found as main memory (e.g. RAM) in servers along with and non-volatile memory (NVM) typically NAND flash. Nand flash based SSDs can be found in cameras (as SD cards), cell phones, iPods, and PDAs, as well as in notebooks, net books, laptops, tablets, and workstations. SSDs are also appearing in larger servers, appliances, and storage systems from consumer to enterprise level.
