I am seriously considering getting a eSATA card instead of USB3. I know eSATA is not as fast as USB3 can be, but I prefer to be 100% stable and accept 100-150 MB/s.
Esata is just an external interface. If you use a Sata III card then your speed will be faster than USB3.
I have a esata bracket hooked up to a Highpoint Rocket 640L. There is also the CalDigit FASTA-6GU3 and Rocket 1144E which have both esata and usb3 ports if you want to save some slots.
