R1 CFexpress Type B cards

[dolina]

A bit late to the party but I'm looking to buy 128GB CFexpress Type B cards for a R1.

As I'm the "don't put all your eggs in one basket" type I'm looking to get 128GB cards that has been my size standard since 2015.

I've narrowed it down to:

- $250 — Lexar DIAMOND 4.0 (LCXEXD4128G-RNENG) 3,200 MB/s
- $135 — Delkin POWER G4 (DCFXBP128G4) 805 MB/s
- $130 — ProGrade Gold (PGCFX128GBPBH) 250 MB/s

I'll be using this with mostly EF L lenses such as

- EF 800mm f/5.6L IS USM
- EF 500mm f/4L IS USM
- EF 400mm f/2.8L IS II USM
- EF 200mm f/2L IS USM

Thanks for the ffeedback.

Any should be fine. I have a set of ProGrade Gold 256 GB cards for everyday use, and another set of ProGrade Gold 1 TB cards that I use for shooting birds (lots of precapture and 40 fps shooting).

Why not get somewhat larger cards, if you shoot RAW? If you write simultaneously to both cards (which is what I do), all your eggs are in two baskets from the moment you press the shutter button.
