Will this drive work with a Black Magic Pocket Cinema Camera 6K? Thanks.
Asked by: Charles
The SanDisk Professional 1TB PRO-G40 SSD Thunderbolt 3 Portable SSD (B&H# SAS311TB) has not been tested (nor approved) by Blackmagic Design for use with the Blackmagic Design Pocket Cinema Camera 6K G2 (B&H# BL6KPKCAMG2). However, it does offer high speed write performance and will certainly be more than sufficient for most of that camera's recording formats/CODECs.
