Solid-state drives (SSDs) are the correct answer because they provide high-speed access and low latency compared to other disk types. This makes them ideal for applications and workloads that require frequent read/write operations. HDDs offer larger storage capacity but are slower due to moving parts, making them less suitable for high-speed operations. Tape drives are used for archival purposes due to their high capacity and low cost, but they have significantly higher latency than SSDs. NAS is a network-attached storage device that can be used for file sharing and can be based on different types of drives, but it does not inherently offer the high-speed access of SSDs.
