Seagate BarraCuda V 30GB IDE hard drive

The Seagate ST330013A is a 30GB 3.5-inch desktop internal hard drive from the BarraCuda V series. It operates at 7200 RPM with a 2MB cache and connects via an IDE Ultra ATA100 / ATA-6 interface. The drive is supplied as a bare unit in new condition.

Suits legacy IDE systems.

This drive suits owners of older desktops or industrial equipment that require a replacement 3.5-inch IDE drive with a 1-inch height profile. The 9ms average seek time supports typical operating system and application loads of the era. Buyers who need more than 30GB of capacity or a modern interface such as Serial ATA cannot use this model.

IDE Ultra ATA100 interface determines compatibility

The single specification that decides fitment is the IDE Ultra ATA100 / ATA-6 interface. The host system must provide a 40-pin IDE connector and support the ATA-6 command set for the drive to function. Without that interface the drive cannot be installed regardless of its physical dimensions.
