BMPCC 6K Pro stops recording on Samsung T7 SSD

Hi everyone!

I'm really stuck so I decided to post my question here. Today I was shooting a video for a client in Marrakech on my BMPCC 6K Pro, Constant Bitrate, 8:1, 60 FPS onto my Samsung SSD T7.

I've never had any issues with this setup, but all of a sudden today it kept stopping with recording after 8 seconds, 10 seconds, sometimes 2 seconds. And if I would quickly press record again, I could film for up to like 40 seconds if I was lucky. But then the same trend would happen.

I had another Samsung SSD T7 with me, switched to that one and tried recording. Tried switching the (default) cables, but still the same issue.

I was thinking it was maybe due to the weather, it was about 30 degrees Celcius. But when I shot in Jordan a couple months back, minutes on end there was no issue. And I decided to take a break and live it in a room with AC but that didn't help. And when I switched to 6K full frame and tried recording 24 FPS seconds there was no issue.

I read in the forums that might card might be too slow, but I double checked the specs and it can write up to 500 mbit/s - 1000 mbit/s so this shouldn't be the issue right?

Also, I have never had this problem before. I also formatted both cards before the shoot so there wasn't anything on it.

I saw some people recommend the Angel CFast cards, but they are out of stock and also crazy expensive.

I don't know what I am doing wrong, or if you have any suggestions. But all help is greatly appreciated!

How long and how intense has the SSD been used?

Frequent rewrites using NAND (or other similar technologies) come at a performance cost.

You should consider using a different SSD, e.g. Samsung T7 Shield which is there on the list of officially supported media.

I think I have used it for about a year, the other one maybe 6 months. And I don't have shoots very often, but if I do have one (maybe 2-3 per month) I think I shoot on in for about 3-6 hours but it is mostly 24 fps, and then 2-3 minutes 60 fps.

But indeed, in the beginning not an issue (with the older and newer one that I bought). But even with the new one, I had the same issue yesterday.

Hmmm, I thought all Samsung SSD were the same so I will have a look into that thank you!

Hi everyone,

Thank you so much for your help and feedback, greatly appreciated

After the comments and doing more research, I figured out that even though my Samsung SSD T7 could work doesn't means it is meant for my specific workflow/workload.

So I ordered the Angelbird AV PRO SE (CFexpress type B, 512 GB), I saw in comments that people trusted and used these the most. The website states it can record up to 8K RAW and I shoot in 6K. Plus, I also bought the native card reader just to speed up the process Angelbird CFexpress Type B MK2 (USB-C).

I'm confident that now I shouldn't run into this problem hopefully, hopefully, it will be worth the investment

Thank you so much to everyone, your comments really helped!
