Hard Disk Drives

Enterprise Hard Disk Drives from Seagate Exos and Western Digital Ultrastar — up to 20TB, 7200RPM, SATA 6Gb/s. Built for backup, archival, and 24/7 data center workloads where cost per terabyte matters more than raw speed.

The Seagate Exos series (X16, X18, X20) and Western Digital Ultrastar DC HC series (HC520, HC550, HC560) are both built for 24/7 data center operation — not consumer drives repurposed for enterprise use. That distinction matters for reliability: these drives are rated for continuous operation, higher workload limits, and the vibration tolerance needed in multi-drive arrays and NAS enclosures.

HDDs remain the right choice for bulk storage, backup targets, and archival data that’s written once and read infrequently. Pairing HDDs for cold storage with SSDs for active workloads is standard practice for a reason — it lets you put your budget where performance actually matters while still getting the capacity you need for everything else.

All units are tested before sale and backed by our own warranty and support. If you’re planning a storage refresh or expansion, read our capacity planning guide or contact our team for help sizing the right drives for your workload.
