Lenovo ThinkSystem 16TB 3.5" 7200RPM SATA 6Gb/s Hot Swap 512e HDD

The Lenovo 4XB7A13914 is a 16 TB hard drive built for Lenovo ThinkSystem servers that need high-capacity local storage and steady, predictable performance. It fits a 3.5 inch bay and connects through a Serial ATA interface that delivers up to 6 Gb per second, so it drops into most ThinkSystem hot-swap trays without special cabling or tools.

This drive spins at 7,200 RPM, giving administrators faster access times than a slower nearline disk while still keeping energy demands and acoustics in check. Sector formatting that uses 512e blocks lets the drive work smoothly with modern operating systems and RAID controllers that expect legacy 512-byte addressing, reducing compatibility headaches during expansions or migrations.

The hot-swap design means a technician can slide the drive in or out of a running chassis without shutting down virtual machines or database instances. That capability is especially useful in clustered environments, branch offices with limited maintenance windows, or any data center that prioritizes continuous uptime.

Engineered for 24×7 operation, the drive carries the duty-cycle rating that enterprise workloads require. It is a solid choice for file shares, backup targets, video surveillance archives, or data-lake nodes where large datasets live on spinning media before moving to tape or cloud tiers.
