Pxw-x70 sdxc cards ???

I am ordering the pxw-x70 today and needing to order SD cards with it. I am looking at a few cards but not quite sure what I should get. I am looking at these 2...

Sony 64GB SDXC Class 10 UHS-1 Memory Card SF64UX/TQN B&H Photo

or

Sony 64GB UHS-I SDXC Memory Card (Class 10/U3) SF64UZ/TQN B&H

Any reconmendations on which card I should buy? they are both on sale and want to purchase today. I may use 4k in the future but this camera will strictly shoot XAVC FULL HD at its highest setting for all my shoots. Basically comes down to 94/45 U1 speed or 95/90 U3 speed? or should I get something different in the middle like a 95/90 U1 ?

Right now I'm leaning for the 94/45 as its on $33, but is 45 write speed fast enough ?

I use the 95/90 card as it is the one recommended by Sony. I have not received any errors or problems. 4K is just around the corner so I would go for the higher write speed.

I'm using the Sony 64Gb 94Mb/s ones in my AX100. Never an issue in any mode. Saving ~$10 by getting a slower card that might screw you over definitely doesn't seem worth it!

I have two Transcend Ultimate 64GB SDXC Class 10 UHS-I 600x Flash Cards. Up to 90MB/s Read, 45MB/s Write. I've used them on a couple of jobs, and they've performed flawlessly. So far I'm only working in AVCHD, while waiting for XAVC support in Final Cut Pro X.

Re: Pxw-x70 sdxc cards ???

I hve asked this question in another group with no answer. Are you expecting or has there been any documentation that indicates the PXW-X70 will when upgraded to 4K record internally on SDHC? 10 bit ?
Thanks
Brian

Re: Pxw-x70 sdxc cards ???

The brochure here: https://pro.sony.com/bbsc/assetDownloadController/V-2610_PXWX70.pdf?path=Asset%20Hierarchy$Professional$SEL-yf-generic-153708$SEL-yf-generic-153751SEL-asset-453731.pdf&id=StepID$SEL-asset-453731$original&dimension=original

says "future ability to record in 4K Ultra High Definition", which to me says that the camera will record 4k on board (actually UHD), not just send the signal to an external recorder (though maybe it will do that too). Given that the AX100 already records UHD on board, it would be a crushing disappointment if the X70 couldn't.

As to 10 bit, as far as I know there has been no statement at all on this, or on any other aspect of the UHD recording. But since they're well behind the AX100 in terms of delivering UHD, I'm hoping it will be significantly better in some way.

Thanks! Was wondering what flavour will be coming out the SDI port as well.
Cheers
