No, eSATA is the same as internal SATA except the cable is shielded. 3.0 gb/s (SATA 2) or 1.5 gb/s are not the transfer rates, but the bit rates for the interface. Remove 20% for 8b/10b decoding and encoding and that's the maximum transfer rate. However, if this is connected to a single drive, the most it can burst is about 60 MB/s so the interface is not the bottlneck, the drive is.....

No, eSATA transfers at the same rate as SATA 3.0, so no difference.
