Amazon.com: Lexar 128GB Professional CFexpress Type B Silver Series Memory Card, for Photographers, Videographers, Up to 1750/1300 MB/s, 8K Video (LCXEXSL128G-RNENG) : Electronics

Got this more for doing 4K/ (and experimental 8K) video recording, but, it'll also hold a full vacation of uncompressed RAWs too!In checking read/write speeds on my MacBook Pro I got 1460 mbps write/770 mbps read using a 1GB test file and 890 mbps write/750 mbps read with a 5GB test file. That said, it will easily handle anything I can throw at it using my Z8 which has a huge buffer anyway.Considering I got it at a deal on PRIME day, no complaints even if I'd paid the normal daily price for it. Well worth it and a keeper!

I waited a bit before reviewing this item. I shoot professionally and use high speed shutter speeds on a regular basis. This card records very fast without any issues. You get what you pay for when it comes to cards. This is a keeper for sure.
