A server administrator is deploying a new database server and wishes to maximize the number of IOPS. Which of the following disk types would BEST accomplish this goal?

The correct answer is A. 500 GB SATA SSD drives. SSDs (Solid State Drives) use flash memory with no moving parts, allowing them to deliver dramatically higher IOPS than any spinning hard disk drive (HDD). A typical SATA SSD can achieve tens of thousands to hundreds of thousands of IOPS, whereas a high-end 15,000 RPM SAS drive…

Explanation

SSDs (Solid State Drives) use flash memory with no moving parts, allowing them to deliver dramatically higher IOPS than any spinning hard disk drive (HDD). A typical SATA SSD can achieve tens of thousands to hundreds of thousands of IOPS, whereas a high-end 15,000 RPM SAS drive (option B) typically delivers only a few hundred IOPS. The other HDD options are progressively slower: 10,000 RPM SAS (option C) and 7,200 RPM SATA (option D) deliver even fewer IOPS. For a database server where high-frequency random read/write operations are critical, the SATA SSD is the clear winner despite its smaller capacity.
