Lenovo ThinkSystem ER3 480GB M.2 2280 SATA 6Gb/s Read Intensive SSD

Overview

The Lenovo 4XB7A90049 is a 480GB solid state drive designed specifically for ThinkSystem servers, featuring an M.2 2280 form factor and SATA 6Gb/s interface. It delivers up to 520 MB/s sequential read and write speeds, making it a practical choice for boot volumes, operating system images, and other read-intensive tasks that require low latency and consistent performance.

This read intensive SSD uses 3D TLC NAND technology and is optimized for predictable reliability with an endurance rating of 1 drive write per day and a total of 870 terabytes written. Its compact design allows system builders to save front drive bays for larger capacity storage, fitting well in virtualized hosts, edge appliances, and lab environments.

Key features

• High sequential read and write speeds up to 520 MB/s support fast data access and system responsiveness
• Strong random IOPS performance with 90,000 for 4 KB reads and 15,000 for 4 KB writes ensures efficient handling of small data operations
• Power loss protection safeguards data integrity during unexpected outages, reducing risk of data corruption
• Thermal throttling maintains safe operating temperatures under sustained workloads, enhancing drive longevity
• End to end data protection helps maintain data accuracy throughout the storage process
• Compact M.2 2280 form factor frees up hot-swappable bays for larger drives, optimizing server storage configurations
