Seagate BarraCuda 7200.7 40GB IDE Drive

This Seagate BarraCuda 7200.7 drive offers 40GB of storage on a 3.5 inch form factor. It spins at 7200 RPM with a 2MB cache and connects via an IDE Ultra ATA100 / ATA-6 interface. The bare drive unit measures 1.0 inch in height.

Suits legacy desktop upgrades.

The drive suits owners of older desktop systems that require a replacement IDE hard drive. It is not for users who need larger capacities or the higher sustained transfer rates of contemporary drives. The 8.5ms average seek time and 350 Gs non-operational shock rating reflect the specifications of its era.

IDE Ultra ATA100 / ATA-6 interface decides fit

The single specification that decides compatibility is the IDE Ultra ATA100 / ATA-6 interface. Your motherboard must provide a matching 40-pin IDE connector and support the ATA-6 standard. Without this specific interface the drive cannot be installed or recognised by the system.
