This recorder uses the USB-C 3.1 gen 2 port on the camera.
At continuous bitrate, using the 1TB WD Black SN750 NVMe SSD, if you shoot BRAW 8.1 12K at 30 fps, you record at 452 MB/sec., (3600x452) = (1,627,200/1,000,000)x(49.99)) $81.34 USD per hour.
At continuous bitrate, using the 1TB WD Black SN750 NVMe SSD, if you shoot BRAW 5.1 S16 6K 17:9 at 60 fps, you record at 364 MB/sec., ((3600x364) = (1,310,400/1,000,000)x(49.99)) $65.51 USD per hour.

If you disregard the BRAW 8.1 452 MB/sec. media tested recommendation, this drive might be capable of recording close to the speed BM advertises of 900 MB/sec. for NVME SSDs. 12K DCI 30 fps Q0 records at 361-1.4 GB/sec. 12K DCI 30 fps Q1 records at 301-1.2 GB/sec. 12K DCI 30 fps Q3 records at 181-903 MB/sec.
Some have used USB adapters for NVME SSDs successfully on the BMPCC 6Ks. This could be a good candidate for experimentation.
