I bought an external one, cheaper since it is a ticker one. Perhaps I could try and fit it inside PS4 since it seems like a 2.5" one. Was like 100 something USD at the time (2 years ago).

With Xcloud, Stadia and PS Now he wouldn't have to decide which games get installed on the limited HDD and he wouldn't have to go through install and update processes. The Stream would start an already updated version of the game instantly.

I wouldn't trade ownership and being able to play offline just to avoid having to install games.

Same boat as you. I don't play my console very often, maybe once every few months... But when I do fire it up, the last thing I want to worry about is yet another silly update.
But.. I do however turn my console on twice a month to grab the free Games with Gold... So when I do that, I check to see whether there are any updates for my 400~ game library on my Xbox One X.

Having 13~ Terabytes worth of drive space for my Xbox has allowed me to keep my entire library installed and updated thankfully, which removes allot of the inconvenience factor, it's still there... But significantly less.

Basically the only real answer to your question is... More disk space for more games to be installed and check for updates more frequently.

Or just join the PC Gaming master race instead.

What about electricity?

One thing I like about the Xbox controllers is the ability to hot-swap batteries, always have a dozen or so charged AA's ready to swap over... And when those batteries eventually (Not a matter of if, but when) die, I can easily replace them without dissembling or replacing the entire controller, lithium cells are usually only good for about 1,000 cycles give or take.

Me neither. The disadvantages of game-streaming are (so far) much greater than their advantages.

Nevertheless it would be the solution for the problems in the OT (waiting for installs and updates, not enough space for multiple installs).

my suggestion would be buying a external from Amazon and keeping on top of what you have installed and what you're playing right now, so if you are going to play a game you have it ready to rock, maybe buy a super cheap 1TB external and assign the internal 1TB to yourself and the other to your brother so you don't argue over it?

Right. I think this is a great example of why these services likely *will* take off in the next decade.  It's just so much more convenient.  

Good thing nobody is asking you to trade one for the other.  Streaming is not about to replace the traditional model anytime soon.  There is plenty of room for both, and many gamers can probably afford to subscribe to a streaming service *in addition* to purchasing games like they do now.  That is certainly my plan.

That sounds annoying. I think you have a bunk system. I have never had this happen on either my launch PS4 or the Pro, and I have used them both quite a bit more than you have.

Oh I know it's not an intentional issue or something too common on PS4 Pros. 

I've always hoped it was more so a simple software issue with the PS4 Pro rather than a hardware issue, since the system runs fine otherwise (the only time the OS is slow is in the store or when I'm playing a very demanding game and using the main PS4 menu). 

That being said I guess I should really stop being lazy and look for a fix. It's possible it's just something I need to tinker around with. Usually I just restart my console. It can be annoying though especially when you start a high-octane action game and realize minutes in that your sound is screwing you up
