Seagate Pipeline HD 500GB desktop drive
The Seagate Pipeline HD ST3500321CS is a 3.5-inch desktop internal hard drive with 500GB capacity, 7200 RPM spindle speed and 8MB cache. It connects via a SATA 3.0Gb/s interface and is supplied as a bare drive without cables or mounting hardware. The unit is listed as new condition.
DoD-compliant erase and tested condition
Each drive has been erased to DoD 5220.22 M compliance and tested for functional operation. The drives are not formatted, partitioned or allocated, so the buyer must prepare the volume before use. Up to 25 bad sectors may be present and cosmetic markings or label variations can occur. No accessories or software are included in the bare-drive package.
Suitable for legacy storage upgrades.
This drive suits builders adding affordable bulk storage to older desktop systems or replacing a failed drive in a SATA 3.0Gb/s environment. Buyers who require a pristine zero-defect medium, enterprise-grade reliability or modern 6Gb/s SATA performance should consider other options.

Questions about this item
Will the 8 MB cache need any firmware updates or replacement over time?
The 8 MB cache is fixed hardware on the ST3500321CS and does not require firmware updates or separate replacement.
What limits the 500 GB Pipeline HD during sustained 7200 RPM operation?
The SATA 3.0 Gb/s interface caps maximum throughput, so sustained transfers will hit that ceiling before the platters do.
How much heat and noise does the 3.5 inch drive produce when running all day?
As a 7200 RPM 3.5 inch mechanical drive it generates audible seek noise and measurable heat; ensure your case provides steady airflow across the drive.
