What the PRO-G40 1TB is

The SanDisk Professional PRO-G40 is a 1TB portable solid-state drive built for creative professionals who move large media files between workstations. Its rugged enclosure meets IP68 dust and water resistance, survives a 3m drop and withstands 4000lb of crush force. An internal aluminium core draws heat away from the controller to help sustain high transfer rates during long sessions.

Interface limits you will hit

Thunderbolt 3 delivers up to 2700MB/s read and 1900MB/s write, letting a 50GB project move in 30 seconds or less. Over USB 3.2 Gen 2 the ceiling drops to 1050MB/s read and 1000MB/s write, so the same transfer takes noticeably longer. The drive negotiates the faster protocol automatically when a Thunderbolt 3 host is detected, otherwise it falls back to the USB path without user intervention.

The spec that decides fit

Capacity is fixed at 1TB; there is no larger or smaller option in this specific model. Buyers who need more storage for raw 8K footage or extensive game libraries must look at a different SKU. Conversely, users with modest document or photo archives may find the terabyte excessive for their daily carry.

商品問答

Should I pick the 1TB model or look for a larger capacity?

The listed model is the 1TB capacity; no other capacities appear in the product data.

What do the 2700MB/s read and 1900MB/s write figures mean when the drive is inside my computer?

Those are the peak sequential speeds over Thunderbolt; real-world throughput will be lower and depends on file sizes, workload and host controller.

Does the USB-C port run at Thunderbolt 3 40Gbps or USB 3.2 Gen 2 10Gbps, and what does that cap?

The drive supports both; Thunderbolt 3 reaches 2700MB/s read and 1900MB/s write, while USB 3.2 Gen 2 tops out at 1050MB/s read and 1000MB/s write.
