Product Being Reviewed: OWC Drive Dock


Perhaps the most underrated USB peripheral category, drive converters come in handy whether you are trying to repurpose old internal drives from a retired PC or simply need to hot-swap bare SATA drives with ease.

You will find a bewildering array of choices of adapters, enclosures and docks on Amazon and alike. Expectedly, there are differences in drive-loading design, chassis durability and USB bridge efficiency. These three factors come into play when picking the best drive adapter for your need. But first, you have to pick the right adapter suitable for your drive type.

Choose the Right Kind of Drive Adapter

Things You Need to Know

In-depth Look

OWC USB Drive Dock
OWC is a household name in the Apple community for its aftermarket memory and storage upgrades for Macs. Its USB 3.1 Drive Dock is the latest addition to its growing peripheral line-up. There's another configuration with Thunderbolt 2 in addition to USB 3.1 Gen. 1 (5Gbps). This high-end model at $249 should appeal to performance-oriented prosumers with deep pockets. For the purpose of his article, we put our focus on the USB-only version that retails for $69.

Right off the bat, this is a vertical loading dock with dual slots that allow for simultaneous access to two SATA drives from Windows or Mac. OWC claims it is powered by a pair of ASMedia ASM1153E USB-to-SATA bridge chipsets, which support USB 3.1 Gen. 1 (5Gbps), UASP and SATA III. This is probably as good as it gets in the USB storage adapter world.

Physically, an aluminum alloy should provide adequate protection in the long run. The metal chassis and the power brick inside that give the OWC dock a low center of gravity help keep this two-pound unit from being unstable even when pulling the drive.

On top of the matte black top are two independent power switches for the SATA III slots so you can swap out a drive without interrupting file transfers on the other. And on the back, you will find a two-prong AC plug, standard USB 3.0 and a main power switch. The OWC comes with a 2 ft. USB cable, and is backed by a two-year warranty.

Plugable USB 3.0 Hard Drive Dock
Plugable is a small company that specializes in PC peripherals, largely made up of USB accessories. Their people are very thorough when it comes to answering pre-sale and technical questions on each of their product pages. This gives buyers a peace of mind knowing they have a less chance of running into something peculiar and unexpected because of their PC setup.

In regard to the dock, the single-bay unit sports a lay-flat design that accepts just one SATA drive. It's relatively easy to slide out a 3.5" drive but not so much with a 2.5" SATA. An eject mechanism would, however, make things easier for SSD and laptop drive owners. Internally, Plugable is equipped with an ASMedia ASM1053E SATA III to USB bridge chipset with the latest firmware that supports drive size up to 8TB.

The body is primarily made of ABS plastic. Add in the fact that the design leaves the installed drive mostly exposed and unprotected; the Plugable certainly isn't meant to be lugged around. There's also a heavy-duty 30W power brick, but at least it's robust enough for even the most power hungry drives.

ORICO Tool-free USB Enclosure
This 2.5" enclosure is from ORICO, a Chinese company that sells just about every type and style of USB drive adapter imaginable. It has a strong presence on Amazon, likely due to its aggressive pricing. By design, the enclosure is limited to either 9.5 or 7.5mm 2.5" drive. The micro-USB 3.0 connector on its rear should have no problems powering up the internal drive, especially if it's a SSD.

Getting this is effortless. Simply slide off the back cover, gently insert the drive to the SATA connector, and put the cover back on. A foam piece is included that can be applied to provide padding between a 7.5mm drive and the case. The unit's build quality is comparable to that of Seagate's and Western Digital's off-the-shelf portable USB drives. Nonetheless, the ORICO's plastic body isn't made to be rugged and waterproof so we shouldn't abuse it too much.

The core of the ORICO is a JMS567 bridge from JMicron; it's a USB 3.1 Gen. 1 (5Gbps) SATA III bridge with confirmed UASP support. A 3 ft. USB 3.0 cable comes with package. At current price, this enclosure with a 18-month warranty should work perfectly if you simply need occasional drive cloning or a ten buck solution to pull data off an old internal drive.

Quick Performance Analysis

The purpose of this benchmark was to reveal the full potential of each USB-SATA adapter when paired with one of the fastest SSDs on the market. We conducted two different file tests to better reflect real-world performance. One was transferring a 10GB MP4 (incompressible) between the Samsung EVO 850 250GB and our late 2014 MacBook Pro via USB 3.0. The other test involved copying 990 JPEGs with their total size about 4.7GB back and forth between the aforementioned devices.

Note that all these adapters support UASP out of the box provided you have the supported operating systems as well as compatible USB 3.0 controllers on your PC. As this is late 2016, we assume most of us have upgraded our systems (Mac and Windows alike) to take full advantage of UASP.

As you can see, the ASMedia's ASM1153E on the OWC managed to maintain a lead while Plugable trailing close behind. It's important to note our Plugable dock is from last year whose ASM1053E bridge has been out of production. The version available now is explicitly said to be the same chipset found on the OWC.

Moving onto ORICO, we didn't see anything peculiar until the photo write test during which the on-board JMicron's JMS578 had a serious problem catching up to the other two adapters. There could be something wrong with this particular chipset implementation in the ORICO. We intend on updating the results as soon as more data comes in.

At the end of the day, it's the chipset and firmware that determine the performance - not the brand of the adapter or enclosure.
