Is there much of a performance difference with the SSHD? Also is it only the Elite version that has a SSHD (opposed to the over 1Tb models)?
well when i used a SSHD in the ps4 it launched me into the tower in destiny 4-6 seconds faster than others in my fireteam.
i also loaded into bf4 faster than anyone else so i had my choice of which tank to get into or heli, etc. a lot of people will say 4 seconds is nothing and negligible but it's still 4 seconds and faster than stock. when i used to play bf4 i thought it was the best thing ever. it was no longer a lottery whether i got a vehicle or not i was guaranteed one at the start of every game. that was enough to convince me it's worth it.
it's up to you to decide whether you want the extra space a 1tb elite console offers and the extra small boost in speed the internal sshd offers. the controller is fantastic albeit i only use 2 paddles. the 2 lower down paddles just get in the way so i have removed them.
if you want the elite controller then it's probably worth getting the elite console.
