And just a couple more Phillips screws later, the 2.5" HGST HTS541010A9E680 hard drive is free from its caddy shackles.

While the PlayStation team boasted about the Pro's SATA III support, this stock hard disk drive is rated at 3.0 Gb/s (SATA II).

Or is it? According to various online sources, this guy is actually a 6.0 Gb/s HDD. Regardless, at 5400 RPM this platter drive will never reach SATA III speeds and is pretty similar to the drive we found in 2013.

No worries, though—armed with the right tools and some elbow grease (and a snazzy new 6.0 Gb/s SSD), you can cut your lag load times in half and get back to gaming.
