Our take on the Seagate Enterprise Capacity ST3000NM0025 3 TB 3.5-inch Internal HDD

The Seagate Enterprise Capacity ST3000NM0025 is a 3 TB, 7200 rpm enterprise hard drive with a 128 MB cache and a SAS 12Gb/s interface. It is built for always-on servers and storage arrays, not for a desktop PC: SAS needs a SAS controller, so it will not plug into a standard SATA port. It is a nearline drive meant for bulk data, backups and surveillance-style workloads, and it competes with other 3 TB enterprise drives on sustained throughput and duty rating rather than on capacity. Buyers choose it when they need a cheap-per-terabyte SAS drive for an existing server; home users are better served by a SATA drive.

What reviewers say

Owners of enterprise arrays describe these drives as dependable workhorses for bulk storage, with steady throughput and few early failures. Complaints center on noise, heat and the need for proper SAS hardware.

What people mention
  • NoiseCriticisedOwners say the drive clicks and hums noticeably, which stands out in a quiet room or small enclosure.
  • ReliabilityPraisedUsers in server and backup roles report long service life and few failures under constant load.
  • InterfaceMixedThe SAS interface is valued in enterprise arrays but blocks anyone without a SAS controller.
  • HeatCriticisedReviewers note it runs warm and needs decent airflow in multi-drive bays.
  • PerformancePraisedSequential reads and writes are described as solid for a 7200 rpm nearline drive.

Questions and answers

Will this drive work in a regular desktop PC?
Only with a SAS host bus adapter. It has a SAS interface, not SATA, so it will not connect to a standard motherboard SATA port.
Is it good for a home NAS?
Only if your NAS has a SAS backplane. Most consumer NAS units are SATA-only, so check the model before buying.
How does it compare with a 4 TB enterprise drive?
It offers less capacity per bay but the same 7200 rpm class and SAS interface. If you have free bays, a larger drive gives more room to grow.
Does it support hardware encryption?
This variant does not include Self-Encrypting Drive features. Seagate sells separate encrypted models in the same line.
What is the 128 MB cache for?
It buffers reads and writes to smooth bursty server traffic. It helps most with many small requests, less with large sequential transfers.
Can I mix it with other drives in an array?
Yes, as long as the array supports mixed models. Matching capacity and speed keeps rebuilds predictable.
Where is the Seagate Enterprise Capacity ST3000NM0025 3 TB 3.5-inch Internal HDD cheapest?
At Newegg, for $159.99, as of our latest check.
