Enterprise hard drives (Seagate Exos, WD Ultrastar, Toshiba MG) are CMR drives built for continuous datacenter duty, with higher workload ratings and longer warranties than consumer drives. They are the backbone of serious NAS and home-lab builds, and at high capacities the price per terabyte is excellent. This table ranks new enterprise hard drives on Amazon.ca by live price per terabyte. For tested used units, see our renewed enterprise HDD page.

Frequently asked questions

What is an enterprise hard drive?

A CMR drive rated for 24/7 operation with high workload limits, like Seagate Exos or WD Ultrastar. Built for servers and NAS rather than desktops.

Are enterprise drives worth it for home use?

For NAS and home labs, yes; they are reliable, CMR, and good value per terabyte at high capacity. They are louder and run warmer than consumer drives.

Exos vs Ultrastar?

Both are excellent enterprise CMR lines. Choose on price per terabyte, capacity and warranty rather than brand. The table shows current pricing.
