PS4 Pro's stock 1TB hard drive can't hit SATA III speeds

Sony has skimped out when it comes to the PS4 Pro's hard drive, slapping in a 1TB 5400RPM platter HDD that can't leverage SATA III speeds.

Although Sony's new 4K-ready PlayStation 4 Pro supports SATA III with up to 6 Gbps transfer speeds, the console's stock hard drive only rocks 5400 RPM, meaning it can't even leverage the full transfer speeds of the SATA III protocol.

This bit of news was uncovered by iFixit, who recently tore down the PS4 Pro to reveal its innards. The PS4 Pro's 1TB internal platter drive is rated 3.0 Gb/s, which is actually SATA II speeds...but some outlets seem to report the HDD supporting 6 Gb/s speeds instead. Either way, the 5200 RPM isn't enough to hit the max blistering fast rates of SATA III.

Remember that the SATA III protocol was established for SSDs that were bottlenecked by SATA II speeds, and most new platter hard drives will use SATA III regardless if they can fully tap the protocol or not. To get the most out of the PS4 Pro's transfer speed capabilities, you'll need to pick up a fairly expensive solid state drive.

Despite not being able to fully tap 6 GB/s speeds, PS4 Pro owners have reported that disc game installations are blazing fast on the console. The PS4 Pro also uses a faster Wi-Fi chip that supports up to 5GHz frequencies across 802.11 a/b/g/n/ac protocols, so game downloads will be much faster.

Some PS4 Pro owners have faced some pretty big issues with the system, however: the console itself is displaying blank screens on certain HDR-enabled 4K UHDTVs. Sony has yet to issue an official response to the reports, but many gamers are being told that their TV's aren't 4K ready.
