The PRO-G40 is the portable SSD for editors who refuse to wait on progress bars. Over Thunderbolt 3 it posts sequential reads of 2,700MB/s and writes of 1,900MB/s, and it still runs 1,050/1,000MB/s over USB 3.2 Gen 2 when Thunderbolt isn't around. The enclosure is IP68-sealed against dust and water, shrugs off 3-meter drops and 4,000 pounds of crush force, and ships formatted APFS for Mac-first workflows, reformatable for Windows. Five-year warranty.
Relevant searches: "Thunderbolt SSD for video editing," "fastest external SSD for Mac," "PRO-G40 1TB," and "rugged portable SSD IP68." The dual-mode design is the point: plug into a Thunderbolt 3/4 port for the full spec-table performance (2,700MB/s read, 1,900MB/s write), or into any USB-C machine at 1,050/1,000MB/s — one drive serves the whole studio instead of living on one desk. Note SanDisk's marketing copy on the same page cites higher 'up to' figures; the numbers used here are from the maker's own specifications table for this model. It ships formatted APFS for macOS-first workflows and can be reformatted for Windows. The IP68 sealing plus 3-meter drop and 4,000lb crush ratings make it the drive editors actually throw in the bag for location work, and the 5-year limited warranty matches that professional positioning.
