A server administrator has been asked to make recommendations for purchase of a new database server that will be processing all of the company accounts. One area of concern from prior experience is…

Capacity is explicitly ruled out as a concern by the requirements, since the data volume is small, making it the least relevant criterion for this selection.

RPM is a mechanical drive property that influences IOPS and latency indirectly, but IOPS and seek time are the precise, directly measurable metrics for evaluating transactional storage performance.

IOPS (Input/Output Operations Per Second) directly measures the number of discrete read and write operations the storage device can handle per second, which is the primary bottleneck when a database processes a large number of concurrent transactions.

Seek time and latency measure how quickly the storage subsystem can locate and begin returning requested data; minimizing these values is essential for OLTP database workloads characterized by random, small-block I/O patterns where every millisecond of access delay compounds across thousands of simultaneous transactions.

Form factor describes the physical dimensions of the drive and has no bearing on the transaction throughput or latency requirements described in the scenario.

Bus width is a hardware interface specification and is not a primary drive-selection criterion when evaluating storage performance for a high-transaction database use case.
