What % of that size card do you use on an average day?
With an average of 57-58MB per RAW file - 2,000-3,000 images 115-175GB a day - I have shoots where I have exceed 4,000 a day but these are very rare AND I do not rely on one card for this. In addition to the 650GB and older 512GB also have smaller cards that I use when I have filled my primaries or want the safety of using more than one set of cards.
I shoot both stills and vids -- AND it is the vid files that are huge - I find the shooting High-Quality 8.3k 60p 12-bit N-RAW uses ~0.78 GB/second (measured) [the reference guide say 0.578GB/s] = so a 650GB card last 14-18 mins (this can be a little longer). 4k 120p is about 2/3rd of this and obviously other CODEX and settings eat less storage.
"We" find the Delkin cards in the multiple - 150GB, 325GB and 650GB capacity (ie the newest version) are a little quicker than the previous versions -- some folk have tested and believe the 650GB has the highest sustained write speed -- all are rated at 1,530 MB/s minimum -- note that the advertised speed of cards is the read speed not the write speed.
I also use ProgGrade Cobalt cards -- the newest version come in
165GB, 325GB, and 650GB capacity these cards are slightly slower (minimum sustained write speeds up to 1,400MB/s) but are a little cheaper.
I do not use AngelBird, Lexar, or SanDisk CFE-B Cards -- others do.
You can use a XQD card in the studio or when shooting slow fps -- with no issues. BUT out in the field on a game drive shooting big cat action -- I want the best.
