Capacity and audience

The Maxtor DiamondMax 8S 6E040T0 is a 40GB 3.5 inch desktop hard drive built for the SATA 1.5Gb/s interface. Its 7200 RPM spindle and 2MB cache target entry-level systems that need basic internal storage without demanding high throughput.

Sustained-load behaviour

Under continuous operation the drive delivers a 150 MB/s interface transfer rate while the 10.1ms average seek time and 4.17ms average latency govern real-world access speed. Native Command Queuing reorders pending commands to keep the platter moving efficiently during heavy multi-tasking workloads.

SATA 1.5Gb/s practical limits

The 1.5Gb/s Serial ATA link caps maximum burst throughput well below modern SATA revisions, so the drive cannot saturate faster controllers. Mechanical latency and the small 2MB buffer further restrict random I/O performance, making the unit unsuitable for applications that require quick access to large data sets.

Questions about this item

How much noise and heat does the 7200 RPM DiamondMax 8S generate when running continuously?

The fluid dynamic bearing motor keeps acoustic levels low, while the low-profile 3.5" design improves airflow and cooling during all-day operation.

What existing hardware is required to connect the SATA 1.5Gb/s interface?

A motherboard or controller with a standard SATA data port and a SATA power connector from the power supply are needed to install this 40GB drive.

Will the 150 MB/s transfer rate and Native Command Queuing work with an older SATA controller?

The drive operates at SATA 1.5Gb/s speeds and supports Native Command Queuing, so it will function with any compatible SATA host adapter, though performance matches the 1.5Gb/s link.
