    The data rate of 4k 422 ProRes doesn't even come close to saturate USB3, so how would a TB drive help?

      USB 3 or TB2 does not matter with a 7200rpm HD anyway...

        USB 7200 1TB drive with about 200 MB's on it:

        TB1 w/7200 3TB drive with 2.6 TB's written to it.

        Another TB1 12TB raid with about 9TB's written to it

          Whatever the reasons, I'm also fairly confident that cutting on an internal or fast-connection SSD would indeed make a difference. Maybe give it a try?

            There have been a few small issues with Yosemite and FCP X, at least with 10.1.3. I haven't had any crashes myself, but a few people with specific third-party plug-ins have had problems, and I've had a few general slowdowns which a restart sorted out. I think the latest free update to FCP X 10.1.4 has sorted these out (FCP X certainly launches quicker now) though it's probably too soon to tell. It's also quite possible there are a few lingering issues with the Retina iMacs.

            The issues with a USB hard drive are a little complex, and it could indeed be the problem. When you edit, you're not just pulling a single stream of video, you might be rendering files, writing the latest project changes, scrubbing through lots of clips at once, etc. and you can hit the limits of a single drive pretty quickly.

            Thunderbolt does indeed have more bandwidth than USB and generally works better on the Mac, but the main factor will still be a single spinning disk. A Thunderbolt RAID or SSD will be around 3x faster in raw terms but also much more responsive in general. I've got plenty of USB3 disks here, and even RAIDing two together was nowhere near as fast or responsive as using a TB RAID.

              Are you saying, that you can write to a single 7200 3TB (almost full) spinning drive with 717 MB/sec?

              That is ether a SSD or a RAID, or one of us got something really wrong.

                  that is an entirely different story....that obviously should not be the problem then....but it helps to make that clear from the start....
                  regardless, the 4gb vram in the new imac are still working with a mobile GPU and with the retina 27 screen has a lot of pixels to push around.....and 4K is 4K...fcpx is much more forgiving then resolve but even with a 8core with 2 D700s things slow down considerably when applying effects or layering clips....

                    I love all the suggestions but video playback is smooth. My issue is latency in audio meters and it takes a second or two to stop or start when I hit the space bar. It seems like UI is the issue. For example I can edit faster on my on my 2008 Mac Pro and 2011 MacBook Pro with the same drive even though it is connected via USB 2.0 on those machines. The playback suffers but the UI is snappy.

                      For what it's worth, the New York Times reviewer of the retina iMac liked it enough to buy one. Subscription, of course.

                        I've been using the maxed out iMac 5k along side last generation iMac 27" (also maxed out) and I believe I have anywhere from 20-30% faster render times in Adobe Media Encoder and I get an average of 40fps exporting from Davinci resolve (2.5k DNG to 1080p ProRes) compared to 26-27fps on the older imac. I believe it will perform faster for single threaded applications and a little worse multithread than the last gen Mac pro 8 core. Geekbench gave me around 15100 points on their score.

                        Anyway, this is my experience with this machine.

                          does anyone have an update on resolve performance on the retina imac? i know kholi* (sorry, said captainhook initially) said he'd have some kind of review/feedback up but i haven't seen anything since. and how well does the 5k screen perform when grading without an external 10bit monitor? consider it a low-budget option, since grading will only be handled in-house if that's what the budget dictates.

                          also, another question for those in the know. how well would the entry level mac pro with the dual d300 gpus perform when it comes to working with 2.5K raw? and 4k raw? because of availability, I might have to stick with stock builds, in exception for ram, which i plan to order from OWC anyway. i know blackmagic recommends the 6-core and the dual d500s but i'm still curious how far one would be able to push the stock build.

                            I've had mine for a week and a half. The colours looks pretty accurate to me. I have a 27" cinema display hooked up as well as my 2nd screen, some reason the video shows up with a bit less saturation but I'm not sure if that is a software or hardware thing?

                            Resolve screams on it, I'm only editing BMPCC footage but everything plays back in real time and it renders clips out at least 2x speed.

                            However I'm noticing Premiere is struggling, as soon as I add any effects to my clips it seems to slow down. Multicam is screwed and keeps lagging out, but it could be a software problem as lots of people have complained about it on the Adobe forum since last year and there still doesn't seem to be a fix.

                            I believe the R9 295X is faster than the dual d300's. However I'm pretty sure it should be fine to edit 2.5k on. Probably will do 4k as well, but it might struggle with 4K RAW.

                              hey woop, thanks for the reply. your retina imac is completely specced up? when you mention editing BMPCC footage, are you referring to raw or prores? working with 4k raw isn't necessarily the biggest factor for me, my priority is the ability to get realtime playback on resolve with the 2.5k raw with a good bit of grading.

                              what if the option was a stock retina imac vs an entry level 4c mac pro with dual d300s...which would have the upper hand?

                                Yup I got the i7 and the R9 295X. I'm refering to Prores have yet to try RAW. When I'm rendering out graded prores footage I'm getting about 60fps, which is about 2.5x speed.

                                I reckon the Mac Pro would have a slight upper hand compared to the base model, but in saying that I would rather get the retina just because of the screen.


                                Only downside is that I've discovered there are some serious problems with Adobe products on the new iMac's.

                                https://forums.adobe.com/thread/1626784 This is talking about Illustrator but I'm noticing the exact same problems in Premiere. When you grade in Premiere it can't even play it back but looking at my iStat menu's, it's not utilising the GPU and CPU like Resolve does when your rendering.


                                Hopefully Adobe gets their shit together because the project I'm working on has become a complete nightmare since Premiere is acting up.
