ST31000524AS not in Mid 2011 iMacs?

[paddyr]

I recently purchased a new mid 2011 i7 27" SSD + HDD iMac and notice it has the old 3Gbs Seagate Barracuda HD ST31000528AS in it and not the newer 6Gbs ST31000524AS drive. Given that this system has Thunderbolt cababilities of 10Gbs for external peripherals, what gives with the old technology bottleneck 3Gbs drives? Does this mean that the system bus is still the older style that cannot accommodate the throughput of the 6Gbs drives?

No the system can support up to 6GB/s but Apple chooses to use older drives. Thunderbolt still works as you can boot off an external drive and you can still use files on an external drive.
