1.5 TB 7200 RPM desktop hard drive

The Seagate Barracuda 7200.11 ST31500341AS provides 1.5 TB of storage on a 3.5 inch SATA interface spinning at 7200 RPM with a 32 MB cache. It is built for desktop systems that need a large-capacity mechanical drive for bulk data.

32 MB cache and 3 Gb/s SATA link

The 32 MB buffer smooths burst transfers while the 3 Gb/s SATA connection fits older motherboards and controllers that do not support 6 Gb/s speeds. No additional software or mounting hardware is mentioned in the supplier data.

Suits budget storage upgrades on legacy SATA

Buyers who want faster 6 Gb/s throughput, solid-state speeds or capacities above 1.5 TB should consider other options. Systems limited to the 3 Gb/s SATA revision will operate at the drive's native link speed.

Questions about this item

Will the 32 MB cache need any firmware updates or replacement over time?

The 32 MB cache is built into the drive controller and does not require separate maintenance or replacement.

What limit appears first during sustained transfers on the 3 Gb/s SATA interface?

The 3 Gb/s SATA link caps sustained throughput before the 7200 RPM platters or 32 MB cache become the bottleneck.

How much heat and noise does the 3.5 inch 7200 RPM mechanism produce when running all day?

The 3.5 inch 7200 RPM drive generates typical mechanical noise and warmth for a desktop hard drive under continuous operation.
