Ideal for legacy IDE systems

This Seagate BarraCuda 7200.10 drive delivers 400GB of storage on an IDE Ultra ATA100 interface. It spins at 7200 RPM with a 16MB cache and uses perpendicular recording technology. The 3.5 inch form factor fits standard desktop bays and the unit is supplied as a bare drive in new condition.

Suits owners of older motherboards

Builders maintaining or repairing systems that only accept IDE Ultra ATA100 / ATA-6 connections will find this drive a direct fit. It is not for systems that require a Serial ATA interface or capacities beyond 400GB. The bare drive packaging means no cables or mounting hardware are included.

The deciding specification is the IDE Ultra ATA100

This single attribute determines whether the drive can connect to the target motherboard. Average seek time is 11ms, average write time is 12ms and average latency is 4.16ms. RoHS compliance and Enhanced G-Force Protection are also featured.
