Not quite. The bitrate for Sata III is 6GB/s while the bitrate for USB 3.0 is 5GB/s. You won't notice much (if any) difference in real life performance for the most part. Both are insanely fast. PS4 actually uses Sata II from what I can tell, which is actually much slower than USB 3.0. |
Actually, the peak bandwidth for SATA 2.5 (PS4 internal HDD conector) is around 300MB/s. Peak bandwidth for USB 3.0 is 625MB/s. The bottle neck in both cases is that unless using an SSD you will be hard pressed to find any HDD that can even reach 300MB/s speeds. Not even 10,000rpm drives. So technically, external drives, especially if using n external SSD can theoretically give you higher transfer speeds than whatever drive you put internally.
OT:
I think sony has said external HDD is something they can put in, and I really can't see anyting stopping them from putting it in, I don't even feel there are security holes they need to worry about that can't be easily controlled. I just feel its not at the top of their priority list tho (I honestly can't even imagine what is at this point considerring how many things the PS4 still can't do) and that wiiU and XB1 had to support that feature outta necessity.
A 1TB SSHDD will set you back under $105 now though, not much I know considering if you install 18 50GB games or less its full lol. But if you wait till around november, I am pretty sure you could find 2TB 2.5" HDDs for under $100.
