Cloud computing and flash-based storage, two fast-emerging IT technologies, are driving each other forward as users of Internet-based services like social networks demand near-real-time access to ever-growing amounts of data.
Executives at Web-based companies like MySpace Inc. and Facebook Inc. are calling flash storage technologies vital to the future of businesses like theirs, which must deliver data to thousands of users simultaneously.
"In the last 20 years, spinning disk really hasn't gone any faster, and right now we're really on the cusp of a change with flash technologies," said Richard Buckingham, MySpace's vice president of technical operations, speaking at The GigaOM Network's Structure 09 conference in San Francisco.
Flash storage is faster than hard disk drives because it doesn't need to spin a disk to get to a particular bit of data. With flash technologies like solid-state disk drives (SSD) and PCI Express flash cards, it's possible to read data anywhere in a storage device in less than a millisecond, compared with several milliseconds on a traditional hard disk drive. SSD and flash storage systems also take up less space and use less power than spinning disks.
The data centers of cloud-based companies are so big that all of those benefits really matter, said Andrew Reichman, an analyst at Forrester Research Inc.
Although Corporate Information Technology shops could also take advantage of the performance gains, the high cost of flash technology will likely continue to blunt its progress in enterprise IT, according to analysts.
