Some of the markets that have desired these higher performance SFF SAS hard disk drives include digital

content delivery, medical imaging and the military. Before SAS technology was available, the majority of

medical imaging storage was Parallel SCSI based. To save a typical image file of 3GB in size, it would take

an average of 15 seconds or more. With scalable 3.0Gb/sec SAS technology and using 2.5" SFF hard disk

drives, thereby doubling the spindles' density (12x 3.5" HDD vs. 24x 2.5" SFF HDD in a 2U storage

enclosure), performance can be greatly improved. Each 3GB file can take less than half the amount of time.

This means greater turnover rate on the patients' data/records, which helps quicken the diagnosis and

subsystem treatment for patients. The end result is quicker recovery time. More patients can be seen

within a certain time frame. The ROI made with this SAS technology is realized much sooner than with

previous technologies and products.

For applications within the digital content delivery industry such as Video On Demand (VOD), having higher

throughput due to higher spindle density means less master copies are needed to serve the same amount

of viewers. The cost on the 2.5" SAS HDDs becomes relatively unimportant when compared to the huge

savings realized from reduced copying expenses.
