Legacy capacity and interface

The Maxtor DiamondMax 8S 6N040T0 is a 40GB 3.5 inch desktop hard drive with a SATA 1.5Gb/s connection. It spins at 7200 RPM and includes 2MB of cache. The drive is supplied as a bare unit in new condition.

Upgrade path and use case

This drive replaces older Parallel ATA models on motherboards that only offer first-generation SATA ports. The jump is worth it when a system needs a direct SATA boot device without adding a controller card. It is not for builders who need more storage space or modern throughput.

Capacity headroom and limits

The 40GB capacity handles a lightweight operating system and a small set of essential applications. Average seek time is 10.1ms and average latency is 4.17ms. The drive runs out of room quickly with media libraries, large game installs or modern software suites.

Questions about this item

Will the 3.5" form factor fit my standard desktop drive bay?

Yes, the 3.5" form factor matches standard desktop drive bays and uses the SATA 1.5Gb/s interface for power and data connections.

Connect the drive via SATA, then enable AHCI mode in the system BIOS before installing the operating system so Native Command Queuing functions.

How does the fluid dynamic bearing motor affect long-term maintenance?
