BarraCuda 7200.8 400 GB IDE drive

The Seagate BarraCuda 7200.8 ST3400832A is a 400 GB desktop hard drive with a 7200 RPM spindle and 8 MB cache. It connects through an IDE Ultra ATA100 / ATA-6 interface in a 3.5 inch form factor. The drive is supplied new as a bare unit without cables or brackets.

Suits legacy IDE systems only

This drive fits PCs or appliances that still use a parallel ATA controller and require a 400 GB replacement. It will not work in systems that lack a 40-pin IDE connector or that expect a different physical interface. Buyers needing higher capacity or a modern interface must choose another product.

The IDE Ultra ATA100 interface decides fit

The single specification that determines compatibility is the IDE Ultra ATA100 / ATA-6 interface. If the host board provides a matching 40-pin IDE port the drive will install and operate at its rated 7200 RPM with 8 MB cache and 8 ms average seek time.
