Enterprise 10TB SATA Drive

The Seagate ST10000NM0146 is a 10TB 3.5" internal hard drive built for enterprise storage arrays. It spins at 7200 RPM with a 256MB cache and connects through a SATA 6.0Gb/s interface. The helium-sealed design uses a forged aluminium base to protect against leaks and lower power draw.

Suited for rack-density workloads

This drive targets data-centre operators who need maximum capacity per rack slot and the lowest power per terabyte. It is not suited for builders who require a PCIe or M.2 form factor, nor for laptops or small-form-factor systems that cannot accept a 26.11mm-high 3.5" device.

SATA 6.0Gb/s interface

The single specification that decides compatibility is the SATA 6.0Gb/s interface; the host must provide a matching SATA port and power connector. The 10TB capacity and 7200 RPM speed follow from that interface choice.

Questions about this item

Should I choose the 10TB model or a lower capacity for my storage array?

The 10TB model provides 25% more petabytes per rack compared to 8TB drives, maximizing rack space efficiency for enterprise storage deployments.

What does the 7200 RPM speed mean for real-world performance in a server?

7200 RPM with 256MB cache delivers the highest 10TB HDD performance, enhanced for OLTP and HPC applications with a 20% boost in random write performance from Advanced Write Caching.

Does the SATA 6.0Gb/s interface limit the drive's throughput in a RAID setup?

The SATA 6.0Gb/s interface caps the maximum theoretical transfer rate, while PowerBalance technology optimizes IOPS per Watt for efficient large data transfers in hyperscale environments.
