T410 with external SATA port
Hi I need a second hard drive and I wanted to know which is the faster performance way to do it. Is the external SATA port faster then the CD/DVD 2.5 drive caddy. assuming both had the same speed hard drive

All the SATA ports should operate at the same speed. That is the advantage of eSATA- you get internal quality speeds with an external device.

So I've been thinking about this, and on the T410 they should be the same speed (SATA II). However, that might be different on a T420 or any model with SATA III. I have seen no confirmation that the eSATA port in the newer models operates at SATA III speeds. Also it is my understanding that the chipset in the T420 and other current models supports at most two SATA III connections and then four SATA II connections. Since the HDD and Ultrabay are SATA III the eSATA port must then only be SATA II.
