Enterprise Storage Drive

The Seagate Exos M ST30000NM004K is a 30TB 3.5-inch internal hard drive built for enterprise storage workloads. It operates at 7200 RPM with a 512MB cache over a SATA 6.0Gb/s interface. The drive uses breakthrough areal density of 3TB per platter to deliver massive capacity in a standard form factor. It targets hyperscale cloud, big-data applications and high-density RAID arrays.

Upgrade From Lower-Capacity Spindles

This drive replaces multiple lower-capacity 7200 RPM SATA drives when a single 30TB unit simplifies the storage topology. The jump is worth it when rack space, power budget or drive-count limits make consolidation necessary. Mozaic 3+ technology blends 90% proven components with new areal-density gains for 3× power efficiency per terabyte. Average latency remains 4.16ms for predictable enterprise performance.

Verify SATA Infrastructure First

Confirm the host system provides a SATA 6.0Gb/s port and sufficient 3.5-inch drive bays with 26.10mm height clearance. The bare-drive packaging means no cables, brackets or mounting screws are included. Ensure the RAID controller or backplane supports drives of this capacity and the 147.00mm length. Power and cooling must match the sustained enterprise duty cycle.

Questions about this item

Will the 26.10mm height fit my standard 3.5-inch drive bay?

Yes, the 26.10mm height matches the standard 3.5-inch form factor used in most desktop cases and server chassis.

Do I need a special SATA cable or controller for the 6.0Gb/s interface?

Use a standard SATA 6.0Gb/s data cable and ensure your motherboard or HBA port supports SATA III to get full speed.

How often should I check the 7200 RPM drive's health in a RAID array?

Monitor SMART attributes monthly and run a full surface scan quarterly to catch early sector errors before they affect the array.
