The P5520 SSDs are part of the growing family of PCIe 4.0 SSDs that match the performance of the ThinkSystem V2 family of servers. By having a Gen 4 host interface, sequential performance is doubled compared to Gen 3 SSDs. The NVMe host interface also maximizes flash storage performance and minimizes latency. The P5520 SSDs drives offer 40% and 60% improvements in latency over SAS and SATA SSDs respectively.
Lenovo Read Intensive SSDs like the P5520 SSDs are suitable for read-intensive and general-purpose data center workloads, however their NVMe PCIe interface means the drives also offer high performance. Overall, these SSDs provide outstanding IOPS/watt and cost/IOPS for enterprise solutions.
