Yes, disk games install a portion of the game - this seems to be a PS4 'exclusive' type function. As far as putting a XBO HDD into the PS4, when I mentioned the XBO potentially being hybrid I did a bit of digging and although they are different manufacturers I believe the HDDs are the same ones.

They both install game chunks.
PS4 has better and more efficient game image container it seems.
Some PS4s and xbones ship with same HDD. Artificial data rate cap may be different though (and external HDD on xbone seems to not have a cap)

From my knowledge, there isn't any console with two disc drives 
I wonder why? Cost or not viable even today?

Cost is a relatively minor element when it comes to spinning HDDs but the complexity goes up significantly. With a RAID 1 setup you get extra reliability but added cost and no perf boost. With RAID 0 you get better perf (up to 2x) but twice the risk of disk failure which adds cost (warranty cost specifically).
It adds a lot of complexity and cost for comparatively little gain, I'd wager we'd see a hybrid drive solution (as a single drive or as a separate flash module) first
Xbox has an eMMC 8gb drive for os and app stuff i believe, that might take some of the strain off the internal drive.
None of that is for game I/O though, it acts more like a boost for the O/S itself so that you can get that instant game/OS/TV swapping

New video from DF:
So 30 fps in the hub, and then 60 fps -with drops to MK 59
- during gameplay. Not bad, quite typical in that console

Someone will wrongly interpret your post... Its not Arena, but a hub.So 30 fps in the arena, and then 60 fps -with drops to MK 59
30FPS in the hub while where it is 60FPS that is the arena.
Minimum framerate was at 57FPS which isn't even 10% to be noticeable to anyone.
Watch until the end of the video at 3:29.So 30 fps in the arena, and then 60 fps -with drops to MK 59
Ok, fixed then, I wasn't sure about what to call it.
Seen that, yup, but it happens in an instant, less than 2 seconds. It seems to occur when the camera zooms out.
So it's mostly a solid 60, occasionally missing the update when there's lots of stuff happening on screen.
Would be interesting to know where the tears would drop to if they used adaptive vsync; if they aren't missing the update by much and can quickly recover, that could be a better strategy, avoiding the occasional stutter at the cost of a top-of-screen tear.
Performance looks great, though.

PC master race would probably drop a few tears. PS owners probably drop less tears - kinda used to it. Difficult to tell how many Nintendo tears drop as they're used to solid 60fps, no screen tearing, but if it's not noticeable, not many tears would be shed.
I see what you did there.
An who would drop more tears to know which version of The Witcher 3 is the superior one if they had both the PS4, and one has more resolution and the other is stable, framerate wise?
Loved your explanation, really. Great stuff.It basically misses the vblank of the display (16.67ms for 60Hz display), so it waits for the next interval.
30fps is already a missed interval for a 60Hz display. So let's say, you render a frame under 16.67ms, and that's your first unique frame. That is ready for display, so that's what you see. If the engine takes longer than 16.67ms it waits for the next refresh @ 33.33ms, so the 1st frame is essentially sitting on-screen for two intervals or 1/2*60Hz -> "30fps". If it missed the next interval, then you wait for the next vblank, i.e. 50ms (3/60), which means you're at "20fps" as the frame has now been sitting on-screen for a 3rd interval.
So basically, the frame rates you see will be an integer divide of the display's Hz. e.g. 60, 30, 20, 15, 12, etc. corresponding to the number of intervals the last frame has been sitting on screen.
With triple-buffering you add a second back buffer to the swap chain for the display to grab frames from, so at least one of those should have a completed frame by the time the display needs it, though you get into frame pacing issues for obvious (various?
edit: Please excuse any brain farts in the explanation.
Talking of which, after having seen the DF videos featuring The Witcher 3, all of them, if I had both the PS4 and the XB1 and had to choose which console I'd buy a copy for, I'd go with the Xbox One version, because it is very stable, framerate wise.

That DF article is not representative anymore, and those 22fps drops you mention happened ONLY during cutscenes. Stress test have been performed on the X1 and in the worst conditions the framerate goes down to 25 fps. And by worst I mean the swamp area and a rainy day with cloudy skies and storms.
With respect too. Your examples just say that you are using a hack.
I don't blame you, you need to make life easier for you, I'd do the same. Keep things easy.
If a girl opens her legs for you, would you recite her a Paulo Coelho poem?
It's a case where you take the easy solution. And your solution is easy, it's just that many people don't know about it and that's where the hassle comes from. Thanks for sharing anyways, I certainly could use that software.

My big question for the current generation relates to frame pacing issues.
Why had I never heard of frame pacing issues before the birth of PS4 and X1?
Did no one actually care back then, or is it a new - and to me very odd and avoidable - problem?

Cyan, with all respect, you wouldn't ever consider buying a Playstation and strictly hold everything Xbox dear, so I'm not exactly sure you're the most reliable person to suggest a purchasing decision.
That's a brilliant line! I might have to plagiarise it in the future.
Cyan would be pulverised on the spot by the MS Gods if he ever touched a playstation

It is. It's actually a sentence that got stuck in my head since time ago, from a VERY intelligent person, the arcade geek par excellence -a guy who beats classic arcade games with a single credit, without using any aids, other than his actual skill- who used it when replying to someone who said that he loved what he did and all, although he rebuked him saying that he practiced the toughest arcade games to find flaws in them and find exploits -if not it wold be impossible to beat them with a single credit-.And then he replied using that sentence (comparing arcade machines to said girl, as saying you must take the easy route when you see it), among other things. I liked it very much too.
