320 GB IDE drive for legacy desktops
This Seagate DB35 Series 7200.3 hard drive provides 320 GB of storage on a 3.5 inch form factor. It is intended for older desktop systems that still use a parallel ATA interface. The bare-drive packaging means no cables or brackets are included.
IDE Ultra ATA100 interface requirement
The drive connects through an IDE Ultra ATA100 / ATA-6 interface, which is the single specification that determines compatibility. Motherboards without a native IDE port cannot use this drive without an adapter.
DynaPlay and DriveTrust features for DVR use
DynaPlay technology optimises video streaming performance and power usage for digital video recorder workloads. DriveTrust technology adds content-security functions for digital rights management. These features benefit DVR appliances but do not affect standard desktop file storage.

Questions about this item
How does the 7200 RPM speed affect performance in a desktop PC?
The 7200 RPM spindle provides faster data access than slower drives, reducing load times for the operating system and applications on this 320GB unit.
What does the IDE Ultra ATA100 interface limit in practice?
The IDE Ultra ATA100 interface caps the maximum transfer rate at 100 MB/s, so the drive cannot exceed that bandwidth even if the platters are faster.
Will this 3.5 inch bare drive fit a standard desktop drive bay?
Yes, the 3.5 inch form factor matches standard desktop internal bays and uses the traditional IDE data and Molex power connectors.
