What is the type of SATA interface of ThinkPad E420? Is it SATA 3 or SATA 2?
I notice that this laptop's hard disk drive transfer rate is 3 Gb/s which means it's a SATA 2 HDD, isn't it? Does this also mean the laptop's SATA interface is SATA 2?
I have tried to search lenovo support and product site for this information but I can't find it.
Thanks in advance.

Download HWMonitor and check under "motherboard".
I have an E520, but I presume an E420 isn't much different except for the screen size.
Anyway, it says here that ports 0 and 1 are SATA III.
This means the port where your hdd is installed (port 0) and the msata-port right next to it (port1).
I suppose the port used for the optical device is only SATA II.
