I'm using my Ursa Mini Pro with the Atoch C2S (CFast to SSD adapter) and Samsung 850 Pro SSD's.
After upgrading to firmware v4.4 the camera is dropping frames only on CFast slot 1. The frames are being dropped even with lower CODECs, something that never happened in the past even not when recorded 4.6K RAW.
Slot 2 is working fine as usual.
Tried to check with other SSD's - still drops.
Tried connecting the SSD's to slot number 2 on the Atoch C2S and the cable to CFast slot 1 on the camera - still dropping frames, so it's not the Atoch.
What do you suggest?
Any news on that subject? I'm facing the same problem.
Haven't tried slot 2 yet.
Mini Ursa Pro + Atoch 2 + Samsung 850 pro 512gb
I have downgraded to v 4.3 and still frame drops. It has nothing to do with the v4.4 firmware.
Frames are being dropped with slot 2 as well, but less often (with my luck I guess I'm dealing with two simultaneous problems) . I decided to check all my 850 Pro SSD's.
All my Samsung 850 Pro SSD's (8 of them, bought from various places over the last past year), show inconsistent transfer rate by several benchmark softwares (on Linux and Windows 10). None of them keeps sequential write speeds above 450MB/s as advertized and sometimes speed drops even below 350MB/s. No wonder the camera is dropping frames. Is it normal behavior of the 850 Pro's? Does Cfast behave the same?
