DATA STORAGE

grow. Western Digital’s range of WD Gold® HDDs provide the huge capacity, scalability, low TCO, and cost-effectiveness that businesses of any size need. These HDDs are a great choice for data hubs with massive capacities and continuous data access and are purpose-built for the demanding enterprise data center market. This makes them a great solution for server rooms, tower workstations and RAID arrays for small to large business applications they provide. Available in capacities of 1TB to 24TB 1 , with OptiNANDTM technology in 20TB 1 and above, these HDDs are scalable on demand and tailor-engineered for heavy application workloads of up to 550TB 2 per year, enabling SMEs to enhance their storage mix with an enterprise-grade solution. Broadly compatible with major enterprise operating systems, they offer high reliability in demanding environments providing up to 2.5M hours of 1 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment 2 MTBF: Projected values for model numbers WD241KRYZ, WD221KRYZ, and WD202KRYZ. Final MTBF and AFR specifications will be based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions, workloads of 220TB/year and 40°C device-reported temperature. Derating of MTBF and AFR will occur above these parameters, up to 550TB/year and 60°C (device reported temperature). MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty. 3 Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is

mean time between failures (MTBF) 3 . Specifically designed for improved system responsiveness, power loss protection, and high performance with low latency, the Western Digital® Ultrastar® DC SN655 NVMeTM SSDs alternatively offer enterprise- class speeds with low power consumption. Available in a range of capacities to meet business customer’s specific needs, the SSDs can work alone or perfectly complement the WD Gold® HDDs to handle tough workloads with reliable endurance in a tiered storage environment. Built to a world-class standard, WD Gold® HDDs and Western Digital® Ultrastar® SSDs are meeting enterprise level requirements and delivering the capacity and performance necessary for businesses to scale and grow.
