Weve known for a long time that users will be able to swap out the hard drive in Sonys PlayStation 4 for another model, but what type of drive makes for the best replacement? A 256GB Samsung SSD, a 1TB hybrid drive, and the Sony-issued 500GB standard drive were all used to boot up the console and load various games, with the results unsurprisingly showing the SSD outperforming the original drive across the board. Although the SSD was easily the fastest in most tests, the hybrid drive wasnt far behind, with the gap between the two ranging from one to three seconds. mandatory PlayStation 4 game installs can be as large as 41GB, so the 256GB SSD tested isnt practical for anyone looking to play more than a few games between installs.
