ST3500620SS Seagate Barracuda ES.2 0.5TB SAS 16 MB 3.5" Server HDD

Enterprise 3.5in SAS HDD for continuous-operation capacity tiers with the ST3500620SS

The ST3500620SS is a 3.5in enterprise SAS hard drive designed for stable, predictable performance in legacy SAS storage tiers and general-purpose server environments. It aligns well with CPU-dense platforms where core count and memory capacity outpace per-drive IOPS needs, making it suitable behind SAS HBAs or RAID controllers in 1U/2U systems with balanced airflow and serviceability requirements.

Using CMR recording, the ST3500620SS prioritizes consistent write behavior under sustained workloads, which is critical for RAID rebuild integrity and time-to-recovery planning. Within PCIe-based server architectures, the drive typically sits behind a PCIe SAS controller, enabling scalable expansion via backplanes while keeping host lanes available for NICs or accelerators. This makes the ST3500620SS an efficient choice for mixed storage architectures that separate hot datasets on SSD from colder data on HDD, supporting backup-to-disk and archival tiers without disrupting memory or expansion planning.

Why Choose the ST3500620SS?

The ST3500620SS delivers an enterprise-appropriate density-to-cost profile for SAS infrastructures that require 24x7 duty cycles and straightforward capacity scaling. It supports disciplined operations through predictable rotational media behavior, simplifies standardization across legacy enclosures, and integrates cleanly into RAID and monitoring regimes commonly used in enterprise data centres.

Seagate designs enterprise drives with a focus on continuous-operation reliability, sustained workload stability, and interoperability with established SAS backplanes and controllers. The ST3500620SS reflects this approach by targeting consistent behavior under operational load and compatibility with modern data centre service practices.

Key Applications:

• Legacy SAS capacity tiers
• General-purpose server storage
