About the HUH721010AL42C0
The HGST Ultrastar He10 (HUH721010AL42C0) is a 10TB SAS hard drive built in the 3.5 inch form factor, using a 12Gb/s SAS interface. It is designed for use in servers and storage arrays that rely on SAS connectivity for high capacity bulk storage.
All units listed here come from a batch of 3 drives that were tested and passed. Each drive underwent a full extended self-test across its entire surface, a power-on hours check cross-referenced against an independent on-drive log, a NIST 800-88 sanitize with read-back verification, and a SMART health read covering reallocated, pending and uncorrectable sectors along with power-on hours.
Based on recorded power-on hours, these units fall into the Value tier, with hours ranging from 40,444 to 41,281. This gives buyers a clear picture of the prior usage level before purchase.

HUH721010AL42C0 questions
What kind of workloads is this drive suited for?+
As a 10TB SAS hard drive, it is typically used in servers and storage arrays that need bulk capacity, such as backup targets, bulk file storage or nearline storage pools. It is not a solid state drive, so it is better suited to capacity-driven storage than latency-sensitive workloads.
Is this drive compatible with my server?+
It uses a 12Gb/s SAS interface and a 3.5 inch form factor, so it will work with servers and storage enclosures that support SAS drives in that form factor. Check that your controller and backplane support SAS connectivity before purchase.
What testing does each drive go through?+
Each unit receives a full extended self-test across the whole surface, a power-on hours check against an independent on-drive log, a NIST 800-88 sanitize with read-back verification, and a SMART health read for reallocated, pending and uncorrectable sectors.
What does the Value usage tier mean for this drive?+
The Value tier indicates the drive has recorded power-on hours over 40,000. All 3 units in this batch fall into this tier, with hours ranging from 40,444 to 41,281.
Were these drives sanitized before resale?+
Yes, every unit underwent a NIST 800-88 sanitize with cryptographic scramble, followed by read-back verification to confirm the process completed successfully.
