SSD options for Virtual (and Physical) Environments Part IV: What type of SSD is best for your needs.

By Greg Schulz, Server and StorageIO @storageio

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. Let us build off those and continue to look at what SSD to use for different environments.

SSD options for Virtual (and Physical) Environments, Part II: The call to duty, SSD endurance

By Greg Schulz, Server and StorageIO @storageio

Part I of this series provided the basics around nand flash SSD. Let’s 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.

SSD options for Virtual (and Physical) Environments: Part I Spinning up to speed on SSD

By Greg Schulz, Server and StorageIO @storageio

Solid-state devices (SSDs) are data storage memory (Figure 1) mediums that utilize semiconductor based memories 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.
