I really wish everything would just go to CFEXPRESS cards already. 1400 max write and 1600 offload speeds. This will future proof the memory aspect of the camera and keep us from waiting around with long offload times. Plus the form factor is perfect.
No. Not really. It depends SO MUCH on the interface (USB 3 ? TB 2 ? TB 3 ? Voodoo magic ?), the bus speed, the computer storage speed and other computer components.
For comparison : last may on Cannes Film Festival (where I worked on a multitask gig part editor, part DIT and part camera operator for a Press Agency), offloading our CFAST 2.0 (from San Disk) with the Lexar Pro USB3/TB2 reader onto a workstation PC (i7 6900K, 64 GB of DDR4, GTX 1080, SSDs and so on) via USB3, the speed maxed out around 390 MB/sec. The card is rated at 500, the connection at 625 (5 Gb/sec).
We also had XQD cards. They were rated at 400 MB/sec. The transfer speed maxed out at 200 MB/sec. Same other conditions.
FURTHERMORE, CFExpress uses an XQD slot and maybe that slot is still a licensed property of Sony and one manufacturer might not one to pay those royalties.
Well, according to your B&H link, it's in preorder state and they don't have a release date.
CFAST2.0 are more established on the market, fast enough for 6K Redcode and most probably the slot isn't licensed OR is cheaper to use.
