I was reading an article on the Information Week Web site about using SSDs for accelerating enterprise storage and came across this statement:
“For the most part, the type of SSD that you use in the storage system does not in a significant way impact the performance that you should expect from that tier of storage. The only challenges that form-factor SSDs have are size and power disadvantages vs. other purpose-built designs that look more like memory modules than drives. A flash chip does not need the same volume of space that a HDD needs, does nor does it need the same amount of power. The cost to get to market quickly is a loss of that space and power efficiency.”
That is one of the philosophies behind a relatively new SSD interface spec called NVM Express (NVMe for short). Here’s the NVMe site’s description of the new spec, for comparison:
