Capacity and drive class

The LaCie d2 Professional STHA4000800 is a 4TB desktop external hard drive built around a 7200RPM Seagate BarraCuda Pro enterprise-class mechanism. It is aimed at photographers, videographers and creatives who need high-capacity storage for large photo libraries, video footage and project files. The aluminium unibody chassis helps reduce noise and vibration in a working environment.

4TB capacity and 240MB/s throughput

The drive provides 4TB of usable space with headroom up to 10TB in the product line for growing archives. Sequential transfers reach up to 240MB/s over USB 3.1, allowing rapid movement of large media files between devices. The USB-C connector works with USB 3.0 and USB 2.0 ports, while a Thunderbolt 3 port is also present for compatible hosts.

Upgrade from slower or smaller desktop drives

This unit replaces older USB 2.0 or lower-RPM desktop drives that bottleneck media workflows. The jump is worth it when your current drive cannot sustain the 240MB/s needed for smooth 4K editing or fast library backups. It requires a computer with a USB-C, USB 3.0 or USB 2.0 port running Mac OS 10.12 or later or Windows 10 or later.

Questions about this item

Will the d2 Professional STHA4000800 work with my older PC that only has USB 2.0 ports?

Yes, the drive supports USB 2.0 via the included USB-C to USB-A cable, though transfer speeds will be limited to the 2.0 standard.

How can I confirm the 7200 RPM Seagate BarraCuda Pro drive is delivering the advertised 240 MB/s performance?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test over the USB 3.1 connection; sustained reads near 240 MB/s indicate the enterprise-class drive is performing as specified.

Which cables and accessories ship in the box with the 4 TB unit?

The package includes a USB-C (USB 3.1 5Gb/s) cable, a USB-C to USB-A cable, the external power supply, and a Quick Installation Guide.
