SanDisk Professional PRO-G40 SSD (1 TB)
A pro-tier 1TB SSD topping out near 2,700 MB/s over Thunderbolt 3, wrapped in an IP68 dust/water, crush- and drop-rated body — built for direct ProRes RAW and high-bitrate offload on set. That ruggedness-plus-speed combination makes it the most capable pick in this storage group. The limitation is the host: USB-only laptops won't see full speed, since peak throughput needs a Thunderbolt 3 connection.
