The Lenovo ThinkSystem ST50 V2 960GB S4520 SSD is a high-performance, read-intensive solid-state drive designed for server environments requiring reliable, consistent read speeds and durability. Utilizing advanced 144-layer Intel 3D NAND TLC flash memory and interfacing via a 6 Gbps SATA connection, this 3.5-inch non-hot-swap drive delivers up to 550 MB/s sequential read and 510 MB/s write speeds for improved data access and throughput.

Specially optimized for read-heavy workloads such as boot drives, web servers, and operational databases, it supports up to 90,000 4KB random read IOPS and 43,000 4KB random write IOPS, ensuring fast response times under demanding conditions. The drive provides enterprise-grade data protection features, including AES-256 hardware encryption, full end-to-end data path protection, and enhanced power-loss safeguards, enhancing data integrity and security.

With a robust endurance rating of approximately 3.0 drive writes per day over five years (totaling 5.3 PB written), this SSD is engineered to handle extensive read operations with an impressive mean time between failures (MTBF) of 2 million hours. Thermal throttling management further extends drive longevity by preventing overheating.

Ideal for Lenovo ThinkSystem ST50 V2 and ST45 server platforms, this SSD includes S.M.A.R.T. monitoring support for proactive health tracking and comes with a one-year customer-replaceable unit (CRU) limited warranty. The device’s standard 3.5" form factor fits seamlessly into compatible server bays, ensuring easy integration without hot-swap capabilities.
