Green 1.5 TB desktop drive

This Seagate BarraCuda Green ST1500DL003 is a 3.5-inch internal hard drive with 1.5 TB capacity, a 5900 RPM spindle, 64 MB cache and a SATA 6.0Gb/s interface. It is built for desktop PCs that need large-volume storage while drawing less power than standard-speed drives.

Buyers who need lower power and quiet operation

The 5900 RPM design targets systems where reduced energy use and quieter running matter more than peak transfer rates. It is not suited for workloads that demand the sustained throughput or lower access latency of faster-spinning drives.

SATA 6.0Gb/s interface

The drive connects through a standard SATA 6.0Gb/s port, so the host must provide a compatible SATA data and power connection. No other interface or protocol is supported by this unit.

Questions about this item

What type of SATA cable and power connector does this 3.5" drive need?

It uses a standard SATA data cable and a 15-pin SATA power connector from your PSU.

Will this 5900 RPM drive slow file transfers if I keep an older SATA 3.0Gb/s drive on the same controller?

No, each device negotiates its own link speed; this drive runs at 6.0Gb/s while the older drive stays at 3.0Gb/s.

How can I confirm the Advanced Format 4K sectors are active after installing this 1.5TB drive?

Run a partition tool; it should show a 4 KB physical sector size and partitions aligned to 1 MB boundaries.
