64Gb Extreme Pro SD 2-pack for $64.95
Posted By: Adam, 05-12-2016, 04:12 PM

You can get two Sandisk Extreme Pro 64Gb cards for just $64.95 this week, though a special B&H kit.

These are the fastest card speeds currently supported by Pentax cameras, plus you get a lifetime limited warranty. A great setup for the K-1!

I just bought 3 128gb cards for the K1 last night.
Good deal on these though.

How's the irony?

I saw the price drop a couple of weeks ago, jumped online to purchase two Sandisk 64GB Extreme Pro cards, as per this offer. They arrived this morning, and now there's an even bigger saving to be had. Doh!

Anyhoo, despite travelling half the planet the purchase saved me about $100 on buying them locally. No complaints but some seriously ironic timing.

Man, I placed two orders at Adorama this week. Within the week, B&H had a better price.

This one was only $3 less, though, so not so bad.

Looks like I need a new card or two and these would work well. Today I RMA'd a two year old Extreme Pro card and waiting to hear back on whether they replace it. Part of the case of the card broke and my cam no longer recognizes it, though it works okay in my laptop. Fingers crossed.

Does the K-1 Support 90MB/S write speed ?

I haven't been able to find an exact bus speed for the K-1. Perhaps someone else can tell us.

If you look at these Ricoh specifications, it says, "Storage Media - SD, SDHC and SDXC Memory Card (Conforms to USH-I standards)."

Sdcard.org has a page here that deals with USH bus speeds. If I read the chart correctly, the bus probably has a minimum speed of 50MB/s, and a maximum of 104MB/s.

Even if the speed of the K-1 bus is only 50MB/s, and you have a modern computer capable of fast read speeds, the read speed of a 95MB/s card will cut down the wait time when transferring images to your hard drive.
_______________________________

Update: According to TheCameraStore, the camera is equipped with "Dual SD card slots for memory card flexibility (compatible with SDXC UHS-1 speed class in SDR104 buss speed mode)"

According to sdcard.org, the SDR104 specification is 104MB/s

Thanks Roger,
I was more curious about the write speed because when one does hi speed burst mode, the buffer clears faster with a fast SD card, but to what extend the 90MB/s of the Extreme Pro is faster than other Extreme SD at 80MB/S is not clear in my mind... If the K-1, or the K-3 is able to write at 90MB/S, yes it worth it.... but otherwise the extra dollars are not required... Unless one buy them in the event of a faster future DSLR body...


This is a discussion that I have seen many many times... but nobody can give a clear answer on the Pentax Bodies write speeds...


The bottleneck I am having with downloaded image is not to copy them in the computer, but rather to generate 1:1 previews on Lr...

Yes, it supports the UHS-I bus speed. It can write a bit faster than extreme plus cards, but not quite as far as extreme pro cards. Still, it's good to have the fastest cards available.

The exact figures will be available in our in-depth review

Wish I could have given you a better answer, Sylvain. Guess we will have to wait patiently for Adam!

Regarding Lightroom: try doing that on an almost 10 year old laptop, 1.8Ghz processor and 2GB memory! I quickly found out I don't load up a whole bunch of DNGs at once in Camera Raw (as I do with the K-5IIs PEFs).

I am looking for a new computer. In my research, I found out that Lightroom does better with a higher GHz processor and upper end video cards. Photoshop makes great use of a Xeon processor with multiple cores, but doesn't max out a video card as fast. I also learned that getting a Xeon with multiple cores *and* a high Ghz rating would quickly bankrupt me.

For both Photoshop, and Lightroom, lots of memory is a plus.

A core i5 laptop with a dedicated GPU should be just fine

Another thing to look at is bus speed, both for the USB ports, built-in card reader, and SSD.

Good to know!
So it would be .... let me guess: 80MB/s ?


Extreme (Plus)* = 60MB/s write
Extreme Pro = 90 MB/s write
Extreme Pro UHS-II = up to 250 MB/s !!! (1667X).




* I think they changed the name to only "Extreme" now, but kept the gold label... anyways, they change name all the time to get us mixed up...

Please note, that not all cameras are compatible with UHS-II cards. The K-1 specifications identify it as being UHS-I compatible. I don't know that UHS-II will work with the K-1 or other Pentax cameras. Do you know if this is the case?

The SD spec loves backwards-compatibility, so UHS-II cards will work in UHS-I mode on devices that lack the second row of pins. Whether or not the bus will deliver the maximum possible UHS-I speed will depend on the card itself, but I'd say it's unlikely.

So the bottom line is that UHS-I Extreme Pro cards are at least as good and possibly better than UHS-II cards when used with the K-1.
