About the HUC101818CS4204
The HGST Ultrastar C10K1800 (HUC101818CS4204) is a 1.8TB enterprise hard drive with a SAS 12Gb/s interface in a 2.5 inch form factor. This family is built for server and storage array deployments where SAS connectivity and enterprise-grade reliability features are expected.
Each unit in our inventory is tested individually. Of the 3 drives tested, 2 passed our full battery of checks and are currently in stock. Recorded power-on hours across tested units range from about 19,047 to 21,316 hours, with a median near 21,238 hours, placing these drives mostly in the standard use tier.
Sequential benchmark results show a median read speed of 235 MB/s and a median write speed of 236 MB/s, consistent with what this class of SAS hard drive typically delivers. All units that pass our process have been sanitized using sg_sanitize with read-back verification before being made available.

HUC101818CS4204 questions
What workloads is this drive suited for?+
As a 1.8TB SAS 12Gb/s hard drive, it is typically used in server storage arrays, RAID configurations, and other enterprise environments that call for SAS connectivity rather than SATA or NVMe.
Will this drive work with my server or storage controller?+
It uses a SAS 12Gb/s interface in a 2.5 inch form factor, so it is compatible with systems and backplanes that support SAS drives in that size. Check your controller and chassis specifications to confirm SAS compatibility.
What does your testing process check on each unit?+
Every unit undergoes a sequential and random read/write benchmark, a full extended self-test across the whole surface, a power-on hours cross-check 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.
What do the usage tiers mean for this model?+
Usage tiers are based on recorded power-on hours: light use covers 500 to 20,000 hours, and standard use covers 20,000 to 40,000 hours. Among the units on record for this model, most fall into the standard use tier based on their logged hours.
How many of these drives have passed testing and are available?+
Out of 3 units tested, 2 passed and are currently in stock, while none have been sold yet.
