Lenovo ThinkSystem S4620 480GB 2.5" SATA 6Gb/s Mixed Use SSD

The Lenovo 4XB7A17125 is a 480GB solid state drive that brings steady, low-latency storage to Lenovo ThinkSystem and ThinkAgile servers. It fits a standard 2.5-inch bay and connects through a SATA 6 Gb/s interface, making installation straightforward whether you are adding capacity to a single rack unit or refreshing an entire cluster.

Built on the ThinkSystem S4620 platform, the drive reaches up to 550 MBps for sequential reads and 500 MBps for sequential writes while sustaining 82 000 IOPS for random reads and 50 000 IOPS for random writes. This balance of throughput and input-output performance suits mixed-use workloads such as virtualization hosts, VDI pools, small databases, and analytics applications that need both rapid reads and consistent writes.

Durability is a key advantage. The drive carries a rating of 4.7 drive writes per day and delivers a total endurance of 4.2 petabytes written, so it can handle heavy daily transaction logs or frequent refresh cycles in edge locations without wearing out prematurely. Built-in end-to-end data protection detects and corrects errors before they reach the operating system, and power-loss protection secures in-flight data if power is interrupted.

IT teams will appreciate the hot-swap capability that lets them replace a drive without shutting down the server, reducing maintenance windows to minutes. Whether you manage a data center full of Lenovo racks or a single remote office server, this drive offers a reliable path to higher performance with minimal disruption.
