This is the product: http://www.vantecusa.com/en/product/view_detail/488 Initial notes: The top fan grille looks old school. The 80mm fan ticks, at max speed it's also way too loud to sit on the table next to you. Plastic tray handles feel a bit flimsy but you won't really be using them that often. Don't lose the countersunk head screws, you get one spare but normal drive screws won't fit. The eSATA and USB3 cables could be a bit longer. Performance testing using two Seagate Barracuda Desktop HDD.15 4000GB HDDs in USB3 vs ICH10R Large sequential reads and writes are excellent, less than 5% loss in performance, over 160MB/sec. Multi disk reads and writes I hit the PCI-E 1x limits of the onboard NEC controller at ~250Mb/sec. Small multi disk random read/write drops down to about 120MB/sec (this is about half the performance of the ICH10R) with extremely high active time. The Jmicron SATA PM and USB controllers are getting a work out here. I suspect in eSATA mode the performance would be much better. Has been rock solid the last 3 days reading/writing non stop, no drop outs etc. TL : DR Vantec need to release one with a SATA3 PM solution, otherwise, no complaints about performance here, they're super cheap too.
