1.5 TB SATA desktop drive

This is a new 1.5 TB 3.5-inch internal hard drive spinning at 7200 RPM with a 32 MB cache. It connects through a SATA 3 Gb/s interface and is built for standard desktop bays. The unit arrives with zero hours on the motor.

Suits bulk storage on older PCs

Builders expanding a legacy desktop or replacing a failed drive in a system that only offers SATA 3 Gb/s ports will find the capacity and spindle speed a direct match. Systems requiring 6 Gb/s throughput or a 2.5-inch form factor should look at other options.

SATA 3 Gb/s interface

The drive communicates over a SATA 3 Gb/s link, so the host controller must provide that exact interface. If the motherboard or backplane only supports a different signalling rate, the drive will not operate at its rated speed.

Questions about this item

How much power and heat does the 7200RPM 1.5TB Barracuda produce when running continuously?

The 3.5" 7200RPM mechanism draws typical desktop HDD power and emits moderate heat; ensure your case has airflow over the drive bay for all-day operation.

What cables and host interface does the ST31500341AS need to work?

It requires a SATA 3Gb/s data cable and a standard SATA power connector from your power supply, plus a free 3.5" drive bay or mounting bracket in the chassis.

Will this 3Gb/s SATA drive work reliably on an older motherboard that only supports 1.5Gb/s SATA?

Yes, the SATA interface is backward compatible; the drive will negotiate 1.5Gb/s on older controllers while delivering its full 1.5TB capacity and 32MB cache.
