No when I saw I make confusion started to say I was wrong about the comparision BD vs. HDD... the only part I'm in disagree is that super high speeds of the HDD showed in your graphs... they are lower than that.

If they can read at 120GB/s all the time then we don't really need SSD because the SDDs can't do over 200MB/s constant read too.

That is my point... Sony just didn't wanted to implement it on PS3... there are nothing to do with memory.

only 7 gb ???!??!

What??????

When you turn off your PC/XBox/PS3/PS4/NextBox, the game (or whatever you did) is completely gone within a few dozen milliseconds. Or are you suggesting that the next consoles have sdd cards that magically cache everything you are doing and magically yell "Lazarus" whenever you kick the power button?

"Turn off" = Cut power = end of session

"Disconnect" = Cut LAN connection = you may be able to continue depending on what you were doing

Allt this "Play instantly while (down)-loading the game" is jusst pr talk. Technically impossible. You will ALWAYS need time to set up the system (when you do it in a clever way, it may only take a few seconds)

And can we please stop this "bd is faster than hd" nonsense discussion?

Like I mentioned before, it also depends on your system's ability to handle the HDD, your system is bottlenecked.

This is the Hitachi 1TB 7200RPM drive I purchased on 12/30/2009, 4GB file tested 5 times back to back:

and just for shits and giggles-

This is a 2.5 inch HDD drive in USB3 enclosure:

This is 2 2.5 inch HDD drives in raid-0 USB3 enclosure:

This is 2 m4 512GB SSD drives in raid-0:

So yeah, your laptop is weak is the reason why your speeds are not very good.

read above, you are very wrong.

Ahh, now I get it! Yes, the read-times are obviously not constant, of course and yes, ssds can't do (but they keep closer to it). All the time is of course not possible. Thing is there is no "real life test". Usually the hdd isn't almost working at all when you have enough ram. In linux there is some logging but it's no big usage. Reading many data is while booting or starting programs (or do coding/compile-jobs) but usually there is not much workload for an hdd so these "stress-tests" are also not showing the real performance.

To make it short: They can be fast and quite slow compared to fastest speeds, yes. But it also very much depends on what you do with them. Hopefully ssds become even more affordable in next years, i can't stand this mechanical crap anymore.

dood, look at my benchmark lol.....

I think what we don't get is that there is no "turn off" - the ps4 will always be powered on (read: always on ;) ) where just an arm-core is still powered so the system itself can do updates on its own or download games when you buy them via webbrowser automatically.

The thing play instantly while downloading is, from my understanding, the gaikai-stuff which is even more in darkness to me - I am sure we won't see it from day one. Technically it just means you can stream the game like any other game but meanwhile it also gets downloaded. As I type it seems quite strange as the download will also limit your streaming experience... hmm.

Let's see what magic Sony will offer to gamers :)

The PS4 main system is tuned off but the ARM is on and mantain the last save state in the main memory (so the memory receive little power like the Stand By in notebooks).

PS4 turn off didn't really turn off the system... you can just do that removing the system from the power supply... even the PS3 never really turn off... that is the reason you can just press the button in PS3 controller to turn it on... my TV stay in the Standy By mode too... I think every eletronic never turno off today (the led is always on to receive input from the controllers).

The amig about the Gakai and play the game while download I don't know but both PS4 and Nextbox have this feature.
