Professional Desktop Storage

The SanDisk Professional G-DRIVE PROJECT is an 18TB desktop external hard drive built around a 7200RPM enterprise-class drive. It connects via Thunderbolt 3 and delivers sequential read and write speeds up to 260 MB/s. An integrated PRO-BLADE SSD Mag slot adds a dedicated bay for removable SSD magazines. The aluminum enclosure houses the drive and includes an AC power adapter.

Creative Workflows and Single-Volume Archives

This drive suits professionals who need a single high-capacity volume for active project files, media libraries or local backups. The Thunderbolt 3 interface supports daisy-chaining up to five additional devices through the second port. Buyers who require redundant RAID protection or portable bus-powered operation should consider alternative configurations. The desktop form factor also requires a wall outlet for the included power supply.

Docking Slot and Daisy-Chain Ready

The bundled Thunderbolt 3 cable provides the host link and enables the second port for downstream peripherals. The PRO-BLADE SSD Mag slot lets editors offload camera media directly from compatible magazines without a separate card reader. An AC adapter is included so the drive and slot receive consistent power under sustained workloads. Both accessories are packed in the box for immediate deployment.

Questions about this item

Does my computer need a Thunderbolt 3 port to use this drive?

Yes, the drive uses a Thunderbolt 3 (40Gbps) interface for data and power, so a compatible port is required to reach the rated 260 MB/s speeds.

Can I daisy-chain an older Thunderbolt 2 device through this drive?

The unit provides two Thunderbolt 3 ports for daisy-chaining, but Thunderbolt 2 devices would need an adapter and would operate at their own lower bandwidth limit.

How can I verify the internal 7200RPM Ultrastar drive is performing correctly?

Run a benchmark over the Thunderbolt 3 link; sustained sequential read and write results near 260 MB/s confirm the enterprise-class drive is operating as intended.
