SSDs are the best choice for I/O-intensive workloads. They provide up to 100 times the  throughput and 10 times lower response time than 15,000 revolutions per minute (RPM)  spinning disks. They also use less power than traditional spinning disks. Serial-attached Small Computer System Interface (SAS) enterprise drives rotate at 15,000 or  10,000 RPM. If an application requires high performance data throughput and continuous,  intensive I/O operations, enterprise drives are the best price-performance option.
