Seagate ST3802110A 80GB 7200 RPM 2MB IDE 3.5" internal hard drive

80 GB IDE drive for legacy desktops

This Seagate BarraCuda 7200.9 model ST3802110A is a new 3.5 inch internal hard drive with an 80 GB capacity. It spins at 7200 RPM and uses an IDE Ultra ATA100 interface with a 2 MB cache. The bare drive suits repairs or upgrades on older desktop systems that still rely on parallel ATA connections. Average seek time is 11 ms and average latency is 4.16 ms.

Suits vintage PCs and industrial gear

Builders restoring period-correct machines or maintaining industrial equipment that requires a 3.5 inch IDE drive will find this unit compatible. The 350 Gs non-operating shock rating and 3D Defense System add physical robustness. Buyers who need more storage capacity or a modern Serial ATA interface should look at something else, as this drive is limited to 80 GB and the legacy IDE standard.

IDE Ultra ATA100 interface decides fit

The single specification that determines whether this is the right part is the IDE Ultra ATA100 / ATA-6 interface. Only motherboards or controllers with a 40-pin parallel ATA connector can use this drive. Verify the host system supports this exact interface before purchasing, because no adapter or converter is included with the bare drive.
