Seagate Exos X24 16TB Enterprise Hard Drive (ST16000NM007H) – SAS 12Gb/s, 7200 RPM, 512MB Cache, CMR

The Seagate Exos X24 16TB (ST16000NM007H) is a 3.5-inch enterprise hard drive for servers, data centers, large NAS arrays and homelab builders. 7200 RPM operation, SAS 12Gb/s connectivity and a 550TB/year workload rating deliver dependable 24/7 capacity. It is a strong fit for backup targets, virtualization hosts and scale-out storage.

Enterprise capacity built for always-on servers.

Built for Continuous Server and Array Duty

Servers, backup targets and large NAS arrays run 24/7, with drives sharing vibration and heat in dense chassis. Desktop and entry NAS drives are not rated for that duty cycle, which leads to timeouts, degraded arrays and costly downtime.

The Seagate Exos X24 16TB is designed for enterprise workloads, with a 550TB/year rating and firmware tuned for RAID controllers. At 16TB per drive, it cuts the number of bays needed for the same usable capacity, which lowers power draw and simplifies enterprise storage expansion. The SAS 12Gb/s interface provides dual-port connectivity and full-duplex transfers on SAS HBAs and RAID controllers.

High Capacity per Bay

At 16TB, the drive reduces the number of bays and spindles needed for the same usable capacity, lowering power and cooling per terabyte.

Enterprise Reliability and Monitoring

Rated for 24/7 operation with enterprise workload figures, the drive reports detailed S.M.A.R.T. data for proactive replacement in servers and arrays.

Setup Instructions

How to Install the Seagate Exos X24 16TB

1. Verify your server, NAS or HBA supports 3.5-inch SAS 12Gb/s drives at this capacity.
2. Mount the drive in the correct carrier or tray.
3. Insert into the bay (hot-swap if supported) and confirm it appears in the controller or OS.
4. Add it to a RAID group, ZFS pool or storage volume and enable health monitoring.
