About the ST8000DM004

The Seagate BarraCuda ST8000DM004 is an 8TB SATA hard drive built on a 3.5 inch form factor with a 6Gb/s SATA interface and a 5,400 rpm spindle speed. This capacity and interface combination is commonly used for desktop storage expansion, bulk file storage, backup targets, and similar capacity-oriented roles rather than latency-sensitive workloads.

Each of the 7 units in this listing has been tested individually. All 7 passed testing and fall into the Light Use tier, with recorded power-on hours ranging from 2,754 to 3,097 and a median of 3,040 hours. Sequential benchmark results show a median read speed of 185 MB/s and a median write speed of 182 MB/s across the tested units, consistent with the drive's rated interface and rotational speed.

Every drive underwent a full extended self-test covering the entire disk surface, a SMART health check for reallocated, pending, and uncorrectable sectors, and a power-on hours cross-check against an independent on-drive log. Units were sanitized using ATA secure erase under the NIST 800-88 standard with read-back verification before being offered for sale.

ST8000DM004 questions

What is this drive best suited for?+

As an 8TB 3.5 inch SATA drive at 5,400 rpm, it is suited to capacity-oriented uses such as bulk file storage, backup targets, and general desktop storage expansion rather than latency-sensitive workloads.

Will this drive work with my system?+

It uses a standard SATA 6Gb/s interface and a 3.5 inch form factor, so it is compatible with systems and enclosures that support standard SATA hard drives of that size.

What does the Light Use tier mean for these units?+

The Light Use tier covers drives with 500 to 20,000 recorded power-on hours. All 7 units in this listing fall into that range, with hours between 2,754 and 3,097 and a median of 3,040.

What testing was performed on each unit?+

Each drive underwent a sequential and random read/write benchmark, a full extended self-test across the entire surface, a SMART health check for reallocated, pending, and uncorrectable sectors, and a power-on hours cross-check against an independent on-drive log. Each unit was also sanitized using ATA secure erase under the NIST 800-88 standard with read-back verification.

What kind of performance can I expect?+

Across the 7 tested units, the median sequential read speed was 185 MB/s and the median sequential write speed was 182 MB/s, which is typical for a 5,400 rpm SATA drive of this capacity.
