I shoot 8K raw, and this is what it costs
The freedom is real. So is the storage bill.

I shoot almost everything in 8K raw. The files are enormous. I do it anyway, and here is the trade I am making.
What you get
Freedom, mostly. Shooting 8K raw means I can crop into a frame and still deliver, which turns one shot into several. It means the grade starts from everything the sensor saw rather than from a decision I made in a hurry in the field.
For wildlife that is the difference between a usable frame and a missed one. You cannot ask an animal to move closer, but you can crop.
What it costs
Storage, and it is not a small line item. I run ten blades and two larger systems, and I still run out.
The blades go in the field and come home full. They slot into a reader on the desk rather than being copied over a cable, which is the part that saves real time.
The thing people get wrong
You need solid state to work from. Not to archive, to work from.
Editing and grading 8K raw off a spinning disk is slow enough to get in the way. You need the speed to process from, which in practice means the footage you are actually working on lives on solid state. Spinning disks are for bulk and for the copies you are keeping, not for the timeline you are cutting.
How it is actually arranged
Fast and small in the pack, so the working files travel. Cheap bulk for the copies that just need to exist. A large drive at home where everything lands.
That is three tiers doing three different jobs, and the mistake is thinking one drive can do all of them.
