Using the 15k RPM drives such as part numbers 959R4, 9FL066-057, and ST3300657SS, in applications that use small block, random I/O is an important factor in realizing higher performance benefits. These applications have a tendency to minimize any caching advantages of the storage system. In addition, with applications such as these, the physical access to data on the disk has the greatest effect on overall performance. These small block, random I/O applications reap the greatest benefits from storage-system performance improvements achieved through the drive’s improved seek and rotational latency times.
