SD card

**csa** · 09-02-2016, 11:03 AM

Anyone have experience with this card?

Lexar Pro1000xUHS-II SDHC Class 10 read speed 150MB, write speed 75MB.

I've been using a Sandisk Ultra, and it appears that this card causes freeze ups in K3's for some, including me. So I'm going to get new cards, and wanted some opinions.

Pentax cameras can't leverage UHS-II speeds, but it might not be a bad idea to start future-proofing your memory cards.

For now I'd recommend this:

SanDisk 64GB Extreme PRO UHS-I SDXC Memory SDSDXXG-064G-ANCIN

I have this card, works great and no issues at all... although currently not too many devices can take advantage of the speed because UHS-II support is still fairly new, it is however, backward compatible with older standards. It is the fastest card I have and noticed that when I download the photos to my computer using a SD/USB 3.0 device.

Thanks for your experience with this card, it makes me lean more towards this card.

That's the card I am using in my K-5 and K-5iis (albeit 32GB) and it works likes a charm ...

Adam, there's been no reports of K3's freezing with the Extreme Pro's?

I've used a pair of these cards in my K-3 with over 20,000 shots on the camera and no issues at all with the cards:

Amazon.com: PNY Elite Performance 64 GB High Speed SDXC Class 10 UHS-I, U3 up to 95 MB/Sec Flash Card (P-SDX64U395-GE): Computers & Accessories

They're generally seen as one of the most reliable cards on the market
