so much misinformation... where was it confirmed SATA2? The Jaguar based CPU supports Sata3...

Look at the block diagram on this page... the sata controller is built into the System On A Chip (SOC)
http://techreport.com/review/24856/amd-a4-5000-kabini-apu-reviewed (also I have an a4-5000)

Why would they downgrade the Sata Controller in the custom SOC used on the Ps4?

The drive itself not being Sata3 is a moot point, if its a laptop HDD, its performance is NOWHERE NEAR Sata2 limits.

tl;dr; its Sata 3...

It can easily be restricted to SATA2 in the firmware.

Correct, even IF the interface is physically capable it is easily capped to SATA 2 via Firmware and could well be the case. I have a SATA 3 drive ready for my PS4 but thats only due to SATA 3 being at a close price point to SATA 2 but i was prepare for the fact PS4 would be limited which makes complete sense, do you go for a faster interface that would be bottlenecked by BD Rom read speeds...or do you go for the most mature and reliable interface. Yeah I would go for whats most tried and tested.

PS4 Uses a SATA-III Controller Per tech Dos released to Devs.

However the System only Uses SATA MODE-2 (3GBps) with the Standard 5400RPM Drive it ships with.

Whether or not is uses SATA-2 or SATA-3 with a SATA-3 Drive/SSD is another Story,

SSDs will have Lower Performance due to lack of any TRIM or Alignment Systems.

Whether or not an External SSD on Xbox one will have this issue is unknown, as the Storage system is Governed by the Windows 8 Kernel,

However External Storage is not yet Enabled due to "Scheduling Error", along with several other features.


Both Systems use the same SATA-IIII 6Gbps Controller Built into the APU's Architecture

The problem's not SATA2 or SATA3 anyways, SSDs run greatly on SATA3 as long as you're not obsessed with sequential speeds, which aren't important up to a certain point.

We use SSDs for their 4K and random I/O performance, to fetch a lot of small files. Sequentials aren't the big speedup there.

The moral of the story is the speed increase vs financial outlay for an SSD in the PS4 in my mind just does not scale well, not to mention lower storage capacity.
