Optimal SSDs for Read-Intensive Applications
Kingston is announcing their new DC500R solid state drive. The “DC” in the name stands for “data center” use as these are optimized for read-intensive enterprise applications.
This is the first drive in the DC500 series that implements Kingston’s strict Quality of Service (QoS) requirements to ensure predictable random I/O performance as well as predictable low latencies over a wide range of read and write workloads. Hence the “R” after the DC500 part.
DC500R is available in 480GB, 960GB, 1.92TB and 3.84TB capacities.
How About Mixed-Use Workloads?
Following the DC500R is the DC500M, which will begin shipping next week. Just like with the “R” in the previous 500-series name, the “M” in this case refers to mixed-use workloads. It provides a balance of consistent I/O delivery and high read and write IOPS performance to manage a wide range of transactional workloads.
With 1.3 DWPD (drive writes per day), DC500M is ideal for the high-volume rack-mount server market. It can be for internal drive bay upgrades, hyperscale data center servers and Cloud service providers requiring low-cost, high-performance storage subsystems.
