Played at the same time.
The one on the left was used on all fat PS3s before 2008/2009 with Firmware older than Version 3.00.
The one on the right came standard with all PS3 Slims & Super Slims, and appeared on Fats with Firmware Version 3.00 or newer.
Fun fact: All PlayStations before 2009 (and the PSP) said “Sony Computer Entertainment” or “Sony Interactive Entertainment” on startup, but after 2009, it said the console name.
