Do you really think that they will go with SSDs?

I know that they are finally reaching "affordable" prices (for drives with up to 256GB), but they would still be the most expensive component of the console, as well as presenting a lot of long term problems.

It crossed my mind, but I'm on the fence about it, to be honest - I'm pretty sure devs would love them, but on the other hand they are still quite expensive - that's why I went with potential problem, if they do include them.

Ok.

It's more likely that they will continue their race for capacity and start with 500GB HDDs or even go for 1TB.

Oh, most certainly I think, I'm just curious to see if perhaps they're going to put at least 64GB SSD inside in addition for some hybrid-drive type combo.

You mean something like Intel's Smart Response? Maybe with a small one, something like 30/32 GB to store texture or things like that, but it would still present problems, like NAND degradation.

Imho NAND degradation is pretty much a non issue in the consumer space. At the moment standard 25nm MLC-NAND (no need to go for TLC for such a small amount of storage) most of the time is rated to endure 3000 write cycles (and as you can see here: http://www.xtremesystems.org/forums/showthread.php?271063-SSD-Write-Endurance-25nm-Vs-34nm some can withstand a lot more). Even if you go to something like 19nm in the near future this still will allow around 2000 cycles.

Assuming 32GB of NAND, 2000 P/E cycles  and a avarage write amplification of 3 (probably worse than what's encountered in real world) you can write 10GB of data each day for like 6 years. And who the hell installs a new game (or partial gamedata) with a size of 10GB each day?

 

I'm pretty sure that the PS720 won't have internal HDDs included, and you can just plug in your own external drives (but I'm assuming USB3 for PS720) and so both will have a small amount of NAND similar to the WiiU. How small the amount will be will depend on how they want to use it. If they allow mandatory installs to NAND than of course more will be needed (I'd go for a reserved swap area on the NAND but no real required installs). But you can also just go with a larger amount of DDR3 Ram to store more game data which is still a lot faster than NAND (initial load times of games may be longer in this case of course, as the data has to be written to the RAM at the start).
