Let us continue to look at what SSD to use for different environments and build off the other parts of this series of articles. Part 1 of this series laid out the basics of nand flash Solid State Devices (SSD) with part II discussing endurance and performance. Part III looked at SSD options for virtual servers, VDI or virtual desktop as well as storage for physical server environments, usage and configuration criteria. So which SSD options are best for which environments?

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.

Let‚Äôs continue by taking a look at endurance for storing and retaining data using nand flash SSD. The importance of the first part of this series is to understand the basics of nand flash based SSD in order to make informed decisions on what is the best for your virtual or physical environment. In addition to SLC (high cost, improved duty cycles) and MLC (higher capacity, lower cost), there is also EMLC or Enterprise MLC which is striving for a balance between SLC and MLC characteristics.

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.
