Solid-state drive (SSD) endurance is an important factor in system design. Due to characteristics of flash media, repeated write cycles eventually wear out an SSD.

Current hard disk drive (HDD) technology is reaching the upper plateau of a technology “S” curve, constraining in the near term the ability of manufacturers to increase the storage capacity of a disk drive. Recently, the maximum capacity of HDDs has been doubling every two to three years. In contrast, a decade ago, the maximum
The SAS device interconnect and transport protocol is designed for enterprise-level performance, scalability, reliability and high availability, while SATA is optimized for lower cost and consumer applications. The SAS feature set has clear advantages for performance, scalability and availability as well as a road map in place to 24 Gb/s.
When properly structured, benchmark tests enable IT professionals to compare solid-state drives (SSDs) under test with conventional hard disk drives (HDDs) and other SSDs. To be truly useful, SSD benchmarks should show the performance of the SSD under the kinds of heavy workloads that are typically encountered in enterprise applications.In addition, the benchmark should evaluate
