An administrator is configuring a server that will host a high-performance financial application. Which of the following disk types will serve this purpose?

SAS SSDs combine the high IOPS and low latency of solid-state drives with the robust interface and features of Serial Attached SCSI, making them ideal for demanding enterprise workloads like high-performance financial applications. The SAS interface offers higher throughput, better scalability, and dual-porting for redundancy, which are critical for such environments.

SATA SSDs are fast but typically offer lower performance (IOPS/throughput) and fewer enterprise features compared to SAS SSDs, making them less suitable for the most demanding financial applications.

A SAS HDD with 10000rpm is an older technology that is significantly slower in terms of IOPS and latency compared to any SSD, failing to meet the "high-performance" requirement.

A SATA HDD with 15000rpm is an older technology that, despite its high rotational speed for an HDD, is still vastly inferior to SSDs in terms of IOPS and latency, and SATA generally has lower enterprise capabilities than SAS.
