Storage to Speed: The SSD Technology Evolution


Published on

Enterprise storage has come a long way in computing's relatively brief history. Solid state drives (SSDs) have played a major part in the evolution of that storage. So what have those changes created in terms of components, benefits and applications? Examining the history of SSDs helps paint a picture of what the future will hold.

What Is SSD Storage?
SSD storage is the use of non-volatile memory to replace magnetic media to store data on a long-term basis. While traditional hard disk drives (HDDs) use magnetic platters spinning at high speeds — which are read from and written to by drive heads — SSDs have no moving parts and depend entirely on flash memory to store data, making them much faster at reading and writing data both ad hoc and in a sustained operation. Today's SSDs don't require an additional power source to maintain an electrical current into the device at all times in order to preserve the data, making their reliability on par, from a data integrity standpoint, with a traditional HDD.

What Does the Future Hold?
In the short term, it is fair to expect higher capacity SSDs to become more prevalent in the industry, and that the cost per gigabyte for SSDs as compared to traditional hard drives will further decrease as the market share for SSDs rises. New form factors that increase the number of parallel data transmission lanes between storage and the host bus will emerge to increase speed, and the quality of the NAND storage medium itself — the physical layer of cells that holds the blocks and pages — will improve, offering better reliability and performance, especially as a drive ages from new to used.
