Akito USB 3.1 Drive Enclosure
Native USB-C Reversible Interface
Inside this gorgeous and stylish aluminum USB-C drive case you'll find a full USB 3.1 Revision 2 chipset to deliver up to 10Gbps data transfer rates. The chipset also supports UASP protocol to assure maximum data throughput - especially when combined with a modern SATA III 2.5 inch solid-state flash memory drive. Previous generations of USB backup drive enclosures supported the slower BOT protocol, but this USB 3.1 case's Mac UASP support assures it's ready for the next decade of Universal Serial Bus Mac peripherals and accessories.
Nearly any solid-state drive performs 30-50 percent faster when using UASP protocol supported drive hardware over the previous (and inefficient) BOT block transfer protocol that USB Mass Storage devices have historically used for years.

Above, Sabrent's offering of a plug and go SSD UASP adapter with a reversible Type-C USB 3.1 interface. It's a 10-second MacBook SSD backup drive solution at a very low cost for the 2.5" SATA III solid-state drive of your choice.
The inclusion of USB Attached SCSI Protocol - UASP support for Mac OS X 10.8 and higher in its chipset is critical for getting optimal data transfer rates out of a solid-state drive. Oddly, it seems USB-C UASP adapters and drive docks are reaching the market faster than 2.5" and 3.5" drive enclosures are. But they're on their way: Demand for Mac USB-C accessories won't be strong until millions more Macs (and PC's) ship with the new USB 3.1 interface on their laptop and desktop computers as standard equipment.

What Is UASP Protocol?UASP is an acronym for USB Attached SCSI Protocol and it's far more efficient than USB 2.0's BOT - Block Oriented Transfer used in conventional external USB drives. The primary technical differences between UASP and BOT is that simultaneous, multiple commands on UASP can occur, while BOT can handle just one command at time. The efficiencies of UASP reduces transfer delays, maximizes total USB bandwidth utilization, and therefore enables more efficient and faster data transfers to and from your Macintosh desktop or MacBook laptop. Lower CPU utilization is also a benefit of UAS, leading to better application and system performance during transfers, and lower power/battery demands.
OS X UASP SupportApple added native support for Mac UASP starting with OSX 10.8 Mountain Lion and is included on through OSX Yosemite and El Capitan. You can verify if a drive is using the UAS protocol using Apple's System Report utility from 'About This Mac' in the Apple Menu. External UASP supported devices will show up in Apple's System Profiler as a USB Attached SCSI device instead of appearing as an older USB Mass Storage Class device.
Mac UASP Drive Enclosures And AdaptersThe performance advantages of purchasing a Mac compatible UASP USB 3.0 enclosure, dock or adapter and pairing it with any modern SATA III SSD can deliver over 30%-50% faster Read/Writes overall than a non-UASP enclosure will. When shopping for a USB 3.0 drive dock, case or dongle for your SSD - make sure UASP is explicitly mentioned in the tech specs or product details to insure your solid-state drive will perform it's best.

Although a SATA hard disk can benefit slightly from UASP, the mechanical lags and delays inherent in spinning platter drive mechanisms negate much of the potential performance improvements. Regardless, the smart money is to buy an Apple UASP supported drive enclosure for your DIY Mac backup drive project - you'll be glad you did.
However, while still alive, Steve Jobs really failed to SELL SuperSpeed USB 3.0 as the most exciting, important, critical, mind-blowing technology advancement that it was. A speed jump TEN TIMES FASTER than USB 2.0 is nothing to sneeze at. Though few Mac accessories and gizmos even needed or could take advantage of the speed increase, it was a critical step forward. Especially for multi-drive RAID and SSD backup drive technology, there was a painful need for speed that USB 2.0 (and even FireWire 400/800) just couldn't deliver. And it was backward compatible with slower USB 1.1 and USB 2.0 devices to make the transition invisibly painless.
But Steve Jobs and Intel Corporation had bigger fish to fry. Namely, pushing ThunderBolt I/O connectivity and its much more lucrative per-port licensing fees and vastly more expensive controller chipsets. As such, both Apple and Intel both conspired to delay wide-spread USB 3.0 adoption until the far more profitable ThunderBolt standard was entrenched before they whole-heartedly jumped on the SuperSpeed bandwagon.
Fast-forward to 2015. Though Steve Jobs has since passed, the transition from USB 3.0 to USB 3.1 Type-C is a much, much bigger deal. Apple consumers will be confronted with more than just a physically different, smaller, and conveniently reversible connector. There's the capabilities of charging through the port, and dealing with the new expense of adapters, hubs, dongles and cables to keep devices old and new all working together. Apple users will be far more consciously aware something MAJOR has changed. And, we'll have to cough-up money for new Type-C dingle-dongles, adapters and peripherals to take advantage of it.
Sadly in it's first iteration, the new 12" USB-C Retina MacBook only supports a single USB 3.1 REVISION 1 port - which keeps the data transfer speeds at ~5Gb/s but introduces the new interface. It won't be till 10Gb/s Revision 2 chipsets are broadly implemented on both PC and Mac computers and devices that we'll begin to see the FULL benefits of USB Type-C connectivity.
Many of these USB Type-C adapters, cables and docking stations are either available or will soon be. But it won't be until both Apple and the PC industry ship millions upon millions of USB-C enabled laptops, desktops and gadgets that there'll be much traction - or profitability - in pursuing this transition.
Interestingly, the new 12" MacBook can be expanded by two optional adapter dongles from Apple that support video: One with VGA, the other with DVI. In addition to those video options both adapters feature a conventional USB 3.0 Type-A Female socket and a USB-C passthrough port. What was't announced was a third, Digital AV Mini DisplayPort adapter.
So, what does that say about the role of Mini DisplayPort technology in the USB-C future? It's not clear, on Apple's new MacBook tech specs page it states: the USB Type-C port supports: "USB 3.1 Gen 1 (up to 5 Gbps), Native DisplayPort 1.2 video output," and elsewhere on the page, "up to 3840 by 2160 pixels on an external display."
As such, it's still unclear exactly HOW one is supposed to connect a mini DisplayPort capable monitor to a USB-C port on the new MacBook... Stay tuned...
Apple's use of a single USB-C Gen 1 port on the lefthand side of the New Apple USB-C Retina MacBook laptop is game-changing on many levels. Occupying 1/3rd the space of conventional USB ports, the traditional, bulky USB Type-A port HAD to go if we're to have the razor-thin laptops and handheld phones and tablets we crave.
The USB-C port also consolidates and eliminates the need for a separate charging port. The Apple Mag-Safe connector's functionality is now wrapped into the Type-C port itself. And for convenience, the reversible USB-C plug is NON-Directional - you no longer have to worry about plugging the USB cable in 'the wrong way'.
Apple and 3rd-parties will be offering a range of USB Type-C adapters to ease the 1-port transition. Apple has already announced two rather pricey $79 options: A USB-C to VGA Display Multiport Adapter for an external VGA monitor, and Apple USB-C Digital AV Multi-port Adapter that supports HDMI displays. Both incorporate a pass-through USB-C 3.1 port, the video port, and a conventional Type-A SuperSpeed USB 3.0 port to preserve your existing investment in USB 3.0/2.0 peripherals.
Sadly, whether it's a USB 3.1 Type-C hub, docking station or multi-interface adapter -- at home, most users of the new USB-C MacBook are going to face a chunky, electronic blob of something dangling off their MacBook with a mess of cables splaying out of it tangling up their desktops. Though many of us may already enjoy a range of wireless peripherals such as Bluetooth speakers, a WiFi enabled AirPrint printer, a wireless Mac headset, graphics pad, or other input device, some gadgets we already own simply MUST be plugged into a USB port to work.
As with other (endless) transitions to next-generation technology, there will be added expense and frustrations along the way. Oh, and that blazing-fast ThunderBolt backup drive you paid top-dollar for? I guess we'll talk about that in another blog post...
