The early release of SA/SB/SC had chipset support for SATA 6 Gbit/s, useful for fast speeds in solid state drive. In late 2011, Sony released a BIOS update which disabled SATA 6 Gbit/s speeds (thereafter capped at 3 Gbit/s) for no apparent reason, and without notifying users in the update changelog. A hacked BIOS was subsequently created and spread via the internet which re-enabled SATA 6 Gbit/s speeds.
