The revolution in hard disk drive storage: small 2.5" serial attached SCSI drives.

Article Excerpt
Big changes are coming for the hard disc drive market. As demand grows for disc drives in the consumer electronics industry, an equally robust demand is driving major changes on disc drive products in the enterprise server market.

Enterprise servers have long used the standard parallel SCSI 3.5" hard disc drives for internal storage requirements. Ever-increasing demand for data storage is causing drive manufacturers to re-evaluate the way storage is architected. Parallel SCSI interface technology has reached its maximum potential and is becoming a bottle neck to data processing. The problem comes from multiple disc drives sharing the available data bus bandwidth, which limits the throughput and can slow transaction on intensive applications. This problem becomes exacerbated by the huge growth of reference and transactional data throughout the industry. Transactional data is defined as mission critical information that is utilized daily, and must be accessible 24 hours a day. Conversely, reference data is information that is stored once and accessed infrequently.

Some IT experts expect there to be more data created and stored in the next 5 years than at any time in the history of the world. Requirements like these for large volume data storage, compounded by fast query requirements are stretching the processing capability of parallel...
