That would be because Piss4 is a childish attempt at insulting a console while XBONE is just an abreviation. Also calling the op an "asshat" isn't smart either.

from my understanding full install is mandatory this gen because tranfer rate of the disc drive is too slow compared to the HDD and other parts of the consoles to be able to run from discs....

well at least that's what I understood from XB1... for PS4 I'm not sure, but if it's the same disc drive  I think it will be pretty similar in other words mandatory installs will come with pretty much any game this gen...

now that said I'm planning on going full DD this gen I don't see the issue really ???? storage space is getting cheaper by the minute and it's not like it will be used only for the XB... heck I'll probably set up a new great NAS or something I'll see how this works out....  worst case scenario I'll get a 2TB+ USB 3.0 SSD.... like I have planned to do for ever... I'm just waiting for the right reason, time/price.... seems like 2014 will be it...

and well download I don't really see the issue, I'll just launch the DL at midnight (if we can preorder even better) which would mean I would actually get the game probably earlier than if I bought it physically because I buy online most of the time and even if I go to a local store I never do the midnight line and rarely go the D day.... and I'm pretty sure that is the case for a huge chunk of the gamers population... heck I even get a 6 hour head start since I use US XBL and I live in europe.... so all in all DD will allow me to get games faster than I do today with physical discs...

Yes, mandatory installs will probably remain, but still in the current range of 3 to 10 GB max we see on PS3 games. Games will jump to 30 to 50 GB in size, so we can assume that a 2 TB drive will retain around 45 games and thats a pretty decent amount of games. I'm not so sure about external drives, since games will use disk installs to stream data of both sources (disk and BD), like GTA V, and will require high transfer speeds.

Another MS 180!!!!!!!     The disc's that is,   They seem to now be on the front of the case, rather then the back..   #gamechanger

Dude this is going to be a problem for both nex-gen consoles.  These install sizes are huge, and I can see installing a few AAA games + 'smaller' arcade titles eating up the HDD space quickly.

thanks for the infos

well I was talking in my case which full DD no disc streaming.... and from what I understand this will not happen on XB1... the disk won't even be spining after DRM check from what I get... since the idea was to be able to play without disk first.... now the disk is just here to compansate for the absence of online check requirement that's it....

no for XB there is no other choice than external since we can't change the internal one (or at least not officially) now I don't know what's inside the XB1 but USB 3 is 5Gbps speed unless they use the last SATA revision they'll be at 6Gbps anyway...

Sata isn't required to saturate the transfer rates of a mechanical drive.
USB 3.0 can sustain around 600MB per second, mechanical Hard Drives typically only top out at 1/4th of that and the internal drives of the Xbox One and Playstation 4, due to probably using single 500GB platters rotating at around 5400rpm probably hits 110MB.

What *may* take a hit is burst rates. I.E. The bandwidth from a Hard Drives cache rather than the spinning disks themselves, but in the grand scheme of things, it's likely impact on performance will be anemic considering most data will be sequential and random reads/writes from the disks themselves in a normal gaming situation.

Of course, if you *really* wanted to saturate the bandwidth of USB 3.0 using mechanical storage, your only real option is of course a Raid set-up, like with the Lian Li EX-503 enclosure, so you can combine the performance and/or reliability of 5 drives, your load times should be stupidly short with that. :P

Ok so that's what i thought external USB3 hdd will do just fine if not better??
an that lian li would be kind of over kill...
what would you advise for xb1 a raid set up with 2 good hdd or one good ssd??? Your answer with and without price consideration!! :)

XBone boxes looks like PS3 boxes!!!??
What lack of originality!

This is ridiculous.

Do they expect people to support their XBoxes with dedicated servers for storage? Seriously you just can't justify something like this. I don't even support my system with every game out there, but I still have about thirty games for a system at the end of a generation. Do they really expect me to pop down serious money for external hard-drives over 2TB? Not to mention the time takes before this stuff is finally installed. It seems more and more likely that there won't be an 8th gen system in my house besides the WiiU.
