The Samsung engineers knew what they were doing. Sad the executives were so corrupt it shut the whole thing down. Along with the Quad Core Processor to handle the 28mp sensor to deliver everything they wanted out of it in particular 4k video they needed the support and leverage of the thing apparently can no longer be mentioned you know i.e. it starts with U and ends with II. :^)

The KP in 2018 did have what you claim is needed. The KP had new sensor new electronics including the Accelerator Unit. The one thing it lacks is UHS-II which is, IMHO, the sole reason the specs against the XT-2 are so poor. The XT-2 clears the full buffer of 22 RAW files in 5 to 7 seconds. They are clearing that fast due to the UHS-II bus. The K-3II is even a better comparison as buffer size holds the same amount of files. The reason the K-3II takes so long to clear the "buffer" compared to the XT-2 is the limitation of the UHS-I bus.

swanlefitte why don't you compare the K-3II or the KP with the Fujifilm X-T 2. I did after all point to both Samsung and Fuji as using UHS-II since 2014.
These are very similar cameras with 24mp sensor all released relatively at the same time. The K-3II and KP don't even come close to the numbers the XT-2 delivers due to the UHS-II bus in the XT-2.

Kunzite I think you are a little obsessed here. Please don't project this onto me. I have looked at the numbers and it is pretty clear the advantages of UHS-II.

Show how the GRIII is writing as fast as the NX1? It doesn't fit the narrative because the GRIII performance specs are not even close to what the NX1 delivers.

Rondec the camera division was closed during a major South Korean political scandal involving Samsung that lasted years. The closing of the camera division was a victim of that scandal.

This is completely misleading statement. It only addresses how UHS-I and UHS-II SD cards perform in the NX1's UHS-II bus. This in no way means there is no difference between what a camera delivers using UHS-II bus over UHS-I. The specs of the NX1 proves that. A comparison of the specs of the NX1 and the KP shows what a camera using UHS-II and UHS-I deliver. People using the KP for action photography would welcome the NX1 specs.

The main reason the NX1 and NX500 had such great specs beyond the 28mp sensor which is excellent was Samsung used UHS-II. That was back in 2014. There would have been no 4K video, fps with 28mp sensor etc without it. Fuji also in 2014 used USH-II in the release of the XT-1. The reviews of these cameras reflect the advantage UHS-II brings in performance and responsiveness etc. The DPR review of the XT-1 points this out.
The main reason Samsung shut down the camera division was the on going corruption charges with senior executives. The camera division was a victim of the ongoing scandal.

No you don't when the bus is the weakest point. How can any one claim the entire system will not benefit if you increase the storage bus from 30mb/s to 300mb/s. The best thing about the people in contention about this is they mostly all claim to be you know in the "industry" whether hardware or software. They are the most persistent in arguing against increasing the capacity of the storage bus. You would think the people in the "industry" would all be screaming in favor of it instead there is a continuous parade of opposition against it.
None of biz-engineers numbers add up the way they claim. Imaging-Resources has detailed performance numbers that don't match up to their claims in any way.
The best part to biz-engineers scenario it is all the image processor as the bottleneck that it only processes 45mb/s of data at a time so it takes a second just to process the RAW. It can not process the files fast enough out of the "buffer". Okay then if that is so the K-1 should be twice as slow as the file still has to take another second to right to the SD card through the UHS-I bus because the process isn't really finished till that happens. But that is not what is happening it doesn't take over 2 seconds to process and write each file to the SD card. It would need to happen if what biz-engineer was even remotely accurate to what they are claiming.

In your scenario the K-1 would be twice as slow as it is now if the image processor can only handle 45Mb/s as you claim as the files still have to pass through the slow UHS-I storage bus. You pretend the files don't even pass through the UHS-I bus that the UHS-I bus doesn't have any effect on the files getting to the SD card.
You could increase the speed of the buffer and the image processing unit to handle 5Gb/s in the K-1 and it will not make a difference because in the end the files run into the UHS-I bottleneck. The files are still going take just as long to write to storage no matter how fast they are processed.
You left out the Accelerator Unit which processes the data off the sensor. Ricoh said this speeds up the whole process except when the files reach the storage bus where everything slows down.
If you replace the UHS-I bus in the K-1 with UHS-II you absolutely will get the speed. UHS-II is exponentially faster in a multitude of ways. It's why the rest of the industry has all already moved to it.

biz-engineer The "buffer" does not take 15 seconds to clear because of the image processing engine it takes that long because of the slow UHS-I bus. The images are already processed and are waiting in the "buffer". So go ahead prove that the reason already processed files in the "buffer" take so long to write to the SD card because of the image processing engine.

Again reh321 the misunderstanding is the KP needs a "buffer" like the K-3 when what it really needs is UHS-II this is whether or not people are posting about it.
---------- Post added 06-30-19 at 04:30 PM ----------
Yes biz-engineer it is a matter of a bottleneck in the image data pipeline. Isn't it easier to just move to UHS-II instead of creating a raid out of two UHS-I slots? The real solution to getting rid of the bottleneck is moving to UHS-II.

Kunzite your statement debunks nothing the "buffer" fills up so fast while you are taking a full sequence of an airplane exciting a low pass because the UHS-I bus is inadequate to empty the filling "buffer" fast enough. The same sequence with UHS-II you will have trouble filling the "buffer". The crawl doesn't happen because the "buffer" is full. The crawl happens after the first image is captured because it takes over a second to write each file from the "buffer" to the card due to the slow storage bus. It is not that hard to understand here Kunzite. Honestly why the argument? Because you want me to be completely and utterly wrong?
And no Kunzite I am pretty sure I am not alone here. I am just willing to put up with the abuse.

No you are directing your frustration at me. My life experience has often shown just because people are all in agreement doesn't mean they are right. I don't even understand such question's like what do you think you are going to change anyones mind. It is either you comprehend the facts or you don't. The wisest man can not help anyone past that argument.

reh321 I love how everyone seems to know what I don't understand. It wasn't that long ago how you posted for Ricoh/Pentax to stay solvent they needed to do autofocus like Canon.
Now when it comes to a discussion about the industry standards concerning the storage bus nobody should care.

reh321 as an actual user the misunderstanding is the "buffer" is to small and or not fast enough. What makes the "buffer" seem to small and or not fast enough is the UHS-I storage bus is in adequate to handle the large files trying to leave the "buffer". The "buffer" can not "clear" or "empty" fast enough to make room for more images because of the bottleneck UHS-I creates for such large files.

Larrymc sorry you feel that way. What I think you are really frustrated in are the responses to my posts. That is what is really irritating to you. I am just stating the industry path. It is not whether "I" am correct or not and it is not even a maybe. I am not trying to have an argument I am just stating the fact for Ricoh/Pentax to stay competitive they need to move to where the rest of the industry has already gone. Who has debunked that or proved me not correct? I don't see you calling those posts inane. They are continuous.

Good grief Kunzite there is clearly one person obsessed here. You have not debunked any thing I have said. You just post in circles finally you agree moving to UHS-II is the path forward for Ricoh/Pentax now you are back to UHS-I is adequate enough. How do I reevaluate my position to suit you by saying UHS-I is adequate enough when it is not?
I have only be stating the facts the industry has set forward. So in your mind you are debunking what they say not what I am saying. It's just patently false to claim the GRIII would not benefit from UHS-II. The GR is Ricoh's flagship premium APS-C compact camera. If there was a camera in the Ricoh line up that should have UHS-II by now is the GR line.
The GRIII isn't any more responsive than the GRII according to Imagine-Resources which I said would be the case. I have a GRII. I love the camera. I use it almost everyday. As performance goes during use the GRII is barely mediocre. The only saving grace is the image quality. The only reason for me to move to the GRIII is the substantial increase in image quality the 24mp 14bit files bring.
I have been using a 32GB UHS-II Lexar card in my GRII which was not any more expensive than UHS-I cards. Imagine-Resource claims there is slightly better performance for the GRII to use such a card. The biggest improvement comes when downloading several hundred images using UHS-II card reader. Instead of minutes it only takes seconds.

What's the point photoptimist? That you can post something that contradicts what I point out? The opposite doesn't occur. You only make my point. The UHS-I bus only communicates in one direction at a time so the other functions can not even compete for access they have to stop and start. The more images you take the longer the stop and start delays last.
So you are against Full and Half Duplex communication with the storage device for what reason? Because I say it is a benefit?

phoebus lets hope Ricoh/Pentax doesn't follow what they did with the GRIII because they left out UHS-II. The GRIII is exponentially a better camera if they included UHS-II.
The reason the K-1 has multiple performance problems is due to the substandard UHS-I storage bus Ricoh/Pentax used in the camera. It doesn't matter for the K-1 whether or not UHS-I can attain 104MB/s speeds the UHS-I bus in the K-1 is the slower controller that does less than half of that which is the root cause to all the issues. It was a mistake for Ricoh/Pentax to use such a slow storage bus controller in a camera with a 36mp sensor creating files to large for it to handle. The GRIII even has the slower UHS-I controller.
All the software and hardware upgrades are crippled if the storage bus is 1000x slower than the rest of the system architecture. Ricoh/Pentax has already demonstrated with the K-1 and the GRIII they either don't under stand that or just ignored the consequences hoping the end users would not comprehend.
UHS-I is a dead end even at the highest speed. Ricoh/Pentax to be competitive is long overdue in moving to UHS-II. UHS-II delivers much more than just speed increases it brings Full and Half Duplex to the storage bus which only further makes any other software/hardware upgrades able to reach their full potential.

So you agree to eliminate all the performance problems you listed is to move to UHS-II.
Every thing you listed is cured with UHS-II.
The wake delay is in part due to the UHS-I bus only able to communicate in one direction at a time. This limitation really compounds the problems the slow bus speed is already causing.
Another limitation to Frames per second is the battery. The three pin battery can not produce the charge to increase frame rate beyond a certain point.
UHS-II helps autofocus by freeing up CPU cycles in two ways the faster write speeds and the bi-directional communication to the SD card.
There is no problem with the "buffer" the problem is the slow UHS-I bus. With UHS-II it will be hard to tell the buffer is even being used during normal operation. Even filling the "buffer" the camera will be ready again in seconds.
---------- Post added 06-29-19 at 10:02 PM ----------
The major bottleneck in the K-1 is the UHS-I bus that is causing the multiple issues. Moving to UHS-II eliminates them. Using the K-1 I am never waiting for the sensor or waiting on the "buffer" to fill. I am always waiting on the "buffer" to clear because the UHS-I bus is so slow to write to storage.
If Ricoh/Pentax does a high end APS-C camera with this new Sony imx571 sensor it will need UHS-II to perform like a high end camera.

No phoebus you are wrong. The K-1 UHS-I bus is using the slower UHS-I standard of around ~35MB/s which is the sole reason it takes so long for the "buffer" to clear. It can not reach the speed you are talking about because it is not the UHS-I bus standard being used. It is not some "part" between the "buffer" and the UHS-I bus causing the slow down. It is the slow UHS-I bus Ricoh/Pentax chose to use in the K-1 that is the problem.
UHS-I is a dead end even at the highest standard for it. The next set of Ricoh/Pentax bodies need to move to UHS-II. There are tremendous benefits to UHS-II that UHS-I can never possibly deliver and the reason all the other manufactures have moved to UHS-II.

phoebus you are completely wrong. The K-1 isn't using anything close to UHS-I 104MB/s speed it is only doing around 35MB/s that is why the K-1 is so slow to write the files from the "buffer" to the SD card. That's why it takes over 15 seconds to clear a full "buffer". Moving to UHS-II the full buffer will clear in less than 5 seconds. The hold up isn't coming from somewhere else. The sensor processors and buffer all function instantaneously. The K-1 has no problem filling the "buffer" but the "buffer" has a problem clearing itself because of the slow UHS-I card bus.
phoebus who are you to tell me to give it a rest? You clearly don't know what you are talking about.

So what you are saying is that you are firmly against improving the cameras by moving to UHS-II for what reason again because you think it isn't about your needs. Nothing I am saying has anything to do with my needs or my believes.
What is responsive to you is just settling for mediocre to me. The SD card bus is some magic thing and will make everything better. You just have to look at Nikon Fuji Panasonic etc. for the evidence to that.
