I love my K-1...What is best SD card/s for a FF like this, what are most other K1 shooters using? Lots of data on one card that can be lost ( I've dropped one through a dock and into into the water), or smaller storage cards, that can be safely stored when full? I consider my SD cards my best back up if data should ever be lost.

I'd be interested to know too. For now I'm using 90mb write speed cards, work fine. But I wonder if getting faster cards would be beneficial?

K-1...What is best SD card/s for a FF like this

Lots of data on one card that can be lost

I have used the Sandisk Extreme Pro 64GB cards in both slots of my K-1. These cards are the same type I've used in previous cameras and have foud them very reliable. The 64GB capacity when shooting RAW DNG gets me at least 800 images but usually it's over 900-1000 but this depends on the subject you're shooting. I have set up my cards for sequential shooting so once one card is full it will switch to the next card and keep recording. If I was more concerned with ensuring I did not lose any images I could set up the camera to create a copy on the second card. This means a back up is made at the time of shooting at the expense of the total number of images, however this should alleviate any fears you have about losing images by a loss of the card or a corrupt SD card. Due to the file size if you went with two 64GB cards you could capture RAW or JPEG to both without losing too much capacity to capture images. If you're one of those sho shoots very small amounts then 32GB would still give you plenty of capacity though I think any smaller means could be limiting. I'd also recommend the Sandisk cards as they used to have recovery software that was downloadable with the Extreme Pro cards. This is no longer available from Sandisk but can be purchased from here if you want it: SanDisk RescuePRO® and RescuePRO® Deluxe Recovery Software

I wonder if getting faster cards would be beneficial?

The buffer on the K-1 isn't that large so the write times are a real pain when shooting Constant High during sports. When shooting events in this drive mode I often hit the buffer with the Sandisk Extreme Pro cards so even if there was an SD card with faster write speeds the limitation is more to do with the camera than the cards themselves. The answer to your question then is there's no real point trying faster cards and to see why the details of the actual write speed are in the review attached at the top of this post. Hopefully future camera models will address the buffer size/write speed bottleneck.

The K-1 has an maximum write speed of 25-30 MB/sec (yes the K3 was faster with 35 to 40 MB/sec), every card that's has faster write speed will work fine.

I'm using an 128 GB SanDisk Extreme 90 mB/s Card, In my last holiday - I didn't delete the files after copying just for testing the file counting - and 2681 raw files fit on the card. Pentax tells me 1612 files will fit after formatting - I got 66% more on the card than predicted.

My second card ist a Transcend TS128GSDU3E SDXC UHS-I U3

I'm using 128 GB cards, because I got a 64GB cards filled in single sessions in my K3, and I don't want to bother about full cards.
I don't want to drop a card and loose it,
My cards are copied to harddisks immediately after a session, and formatted in the camera afterwards.

I run a pair of fast Lexar 128gb cards in mine and have been happy with that. Been running that since it was new and i got mine in the first batch shipped.

I have used the Sandisk Extreme Pro 64GB cards

+1 for Sandisk Extreme Pros with the K-1. Very reliable, very fast.

Thanks, LEXAR is a good product...I have never had a problem with any of their storage devices. Speed is not usually an issue, for my primary shooting is landscape...but with me, who knows. Best regards!

I do believe I'm going to follow your pattern. Thank you for the help. Have a great day!

These are the best cards you can get speed-wise and in terms of durability/longevity:

SanDisk 64GB Extreme PRO SDXC UHS-I Memory SDSDXXG-064G-GN4IN
SanDisk 128GB Extreme PRO UHS-I SDXC Memory SDSDXXG-128G-ANCIN

It's also hard to beat the lifetime warranty. With ever-increasing file sizes, I'm starting to favor the 128Gb version.

There are also newer UHS-II cards, but these are not supported by the camera, so the only benefit would be increased read speed in a PC card reader that's UHS-II compatible. You can also future-proof your cards this way, but I personally think that UHS-II cards are still way overpriced.

Sigh...
Have my K1 on a months holiday. F\Dual Samsung 128 EVO+ micro SD cards in SD holders. K1 is set to mirror any images taken across both cards.

Just finished taking a great series of a desert sunset. Went back to show them. Turned the K1 on, the orange light came on (as usual), then blinked and came back on (unusual).

Now I have two completely clean (i.e. empty!!!!!) micro SD cards. Lost 4 weeks of images. DEEP sigh...

My fault for not backing up off the K1 to the laptop. Silly me.

Any thoughts as to -why- this happens? And, and thoughts on perhaps recovering any/all of the images?

Heading out to tomorrow first thing to buy -new- cards regardless.
