[lug] USB3 vs eSATA III question

[Davide Del Vento]

I don't know anything about your question, but I'm seeing the most
recent/performant (SSD) drives are using PCIe instead of anything
else. I've also heard that booting linux from PCIe can be troublesome,
so I think I'll buy a normal SATA drive (I'm in the market for a small
one).
