Oyen Digital, a popular manufacturer of portable storage enclosures and devices, provided us with its MiniPro™ eSATA / USB 3.0 Portable Hard Drive enclosure for testing USB 3.0 enhanced mode on the ASUS P8Z77-I Deluxe motherboard. This enclosure offers support for USB 2.0, USB 3.0, and eSATA ports in conjunction with a 2.5" hard drive. We put this enclosure on the test bench with the ASUS P8Z77-I Deluxe board to test the performance limits of the device. The MiniPro™ enclosure can be found at your favorite e-tailer for $39.95.

The MiniPro™ SATA / USB 3.0 Portable Hard Drive enclosure is a simple aluminum enclosure supporting any 2.5" form factor hard drive up to SATA III speeds. The enclosure itself supports USB 2.0, USB 3.0, and eSATA connections. Because of its use of the ASMedia 1053e chipset for USB 3.0 support, the enclosure supports both USB 3.0 normal mode transfer speeds and UASP (USB Attached SCSI Protocol) mode transfer speeds. UASP mode is a method of bulk transfer for USB 3.0 connections that increases transfer speeds through the use of parallel simultaneous packet transfers. Per our sources at ASUS, UASP can be explained as follows:

The adoption of the SCSI Protocol in USB 3.0 provides its users with the advantage of having better data throughput than traditional BOT (Bulk-Only Transfer) protocol, all thanks to its streaming architecture as well as the improved queuing (NCQ support) and task management, which eliminated much of the round trip time between USB commands, so more commands can be sent simultaneously. Moreover, thanks to the multi-tasking aware architecture, the performance is further enhanced when multiple transfers occur.
The downside of UASP is that the receiving device (Flash drive/external hard drive etc) must also be UASP enabled for the protocol to work. This requires checking your peripherals before purchase. However since UASP is an industry standard, the device support for ASUS UASP implementation is not restricted to a particular controller manufacturer or device type, so the overall number of peripherals available should undoubtedly grow.

I would buy this in a heartbeat if it came with a gigabit ethernet port, and the software to allow me to connect it to my USB 2.0 laptop's gigabit ethernet port, amd back up my hard drive! One gigabit ethernet is around 2.1 times the bandwidth of usb 2.0 (480 megabits per sec). M$ requires the pro version of windows 7, just to be able to back up to a network location! It is a royal pain in the A$$ ad-hocking over a cat5 cable my usb 2.0 laptops with the one laptop I own that has USB 3.0, via its gigabit ethernet port, but this makes my backups faster! There are millions of older laptops out there with gigabit ethernet cards, but only have usb 2.0 ports, and a drive that could do backups over the eathernet, without having to pay the M$ OS pro-version TAX, would sale like hot cakes, and be a little faster than usb 2.0!

I love my D-Lock eSATAp (eSATA+power)enclosure. My work laptop (Dell Precision M4500)doesn't have USB 3, but it does have eSATAp. However, most of our computers at home just have USB 3, so this enclosure would be great for me.

On the Oyen Digital website is an alternative eSATA cable that is a single eSATAp connector at one end and two connectors at the other: eSATA and DC power. I really wish this cable was included with the enclosure. It's $15 on Amazon (but not available in Canada!). BTW the enclosure is $40 on, but $69 on Crazy difference.
