The 8K120 cameras that Red sells is 1,123 GB per hour which needs some capacious SSD to keep up. CF Express cards are now used which are fast enough for extreme footage. Red uses the CF Express type B cards. Readers are widely available as Red's is $250.

I have a Blueendless USB reader for CF express cards so I can import content from 8K cameras. 8K cameras tend to use 1TB and 2TB cards at present but I figure these are fine for now. The Blueendless reader is < $20 which is slower but it reads video fine. I do not see the type A cards in use much but readers are available for A , B and C type cards.

Some cheap Chinese brands of CF Express B cards tend to be sluggish. I guess the NAND is not as fast as the high end cards but still they work in some older 4K cameras. The 8K120 cameras today are rather demanding. Sandisk CF Express B 512GB are fast but the limited capacity is better for 4K or 8K60

I do not trust any memory cards for permanent storage so I use server hard disks galore and copy footage to them before assembling it with Avid Media Composer. I usually also make copies of footage so in case of errors or mistakes I have a backup copy.

Less costly 256GB and 512GB CD Express B cards are cheaper than 2TB modes. Check performance values as some cheaper brands so not work well even with 4k cameras.

32TB hard disks are a godsend for working on feature films at 8K120 where TBs of video are standard fare.

I have a Satechi TB4 hub with 4K and 8K capability. With 3 ports it can also handle storage galore. It even has three USB 3.1 ports for single hard disk enclosures etc.

No just wanted to call attention to modern use of removable media. I have a Avid license so I do see these cards here and there when I get some compositing work. Avid is strong for major projects.
