DiamondMax 10 300GB IDE Drive

The Maxtor DiamondMax 10 6B300R0 is a 300GB 3.5-inch internal hard drive spinning at 7200 RPM with 16MB cache. It uses the IDE Ultra ATA133 interface and includes native command queuing for improved multitasking performance. This new bare drive suits legacy desktop upgrades or industrial replacements requiring parallel ATA connectivity.

Compatibility Check Before Ordering

Verify your motherboard or controller provides a 40-pin IDE port and supports Ultra ATA133 transfer rates. Confirm the system BIOS recognises drives of this capacity without a software overlay. Ensure a free 4-pin Molex power connector and physical 3.5-inch bay space are available in the chassis.

Build Quality and Daily Use

A fluid dynamic bearing motor reduces acoustic output during seek operations rated at 9ms average seek time and 4.17ms latency. The Shock Protection System and Data Protection System enhance reliability against vibration and write errors. Bare-drive packaging means no mounting screws or cables are included; plan for standard IDE ribbon routing and secure mounting in the bay.

Questions about this item

Does the bare drive include cables or mounting brackets, or must they be purchased separately?

The drive is supplied as a bare unit only. IDE data cables, power adapters and 3.5-inch mounting screws are not included and must be sourced separately.

Is the 300 GB capacity the only option in the DiamondMax 10 line, or are other sizes available?

This model is the 300 GB variant. The supplier data lists only this capacity for the 6B300R0; other capacities would carry different model numbers.

What real-world performance can I expect from the 7200 RPM speed and 16 MB cache on an IDE Ultra ATA133 interface?

The 7200 RPM spindle and 16 MB cache deliver a 9 ms average seek time and 4.17 ms latency, suitable for desktop workloads on an ATA-133 channel.
