1. Booting in RAID 0, RAID 1, and SPAN mode are supported without limitation.

2. The following limitations apply when booting in Independent mode: only the disk connected to Port 2 is bootable when both drives are installed. If only one drive is installed, the disk will boot regardless of which port it is connected to. Please check the Assembly Manual & User Guide for more details.

3. If connecting from a computer with USB 3.1 Gen 1 via Standard-A to USB-C adapter cable, the device will function at USB 3.1 Gen 1 speeds. Currently the Mercury Elite Pro Dual mini is not compatible with the USB-C port on the OWC USB-C Dock. Please connect to one of the USB Standard-A ports instead. Performance is identical on all USB ports on the USB-C Dock.

4. If your USB-C host supports the USB Power Delivery 2.0 specification, it can bus-power the Mercury Elite Pro Dual mini. Other USB hosts may be able to bus-power this device as well. If you find that your chosen host does not bus-power the device, please use the included power supply.

Rating: 5/5 Hidden Jem! October 17, 2020 About to buy my third one of these enclosures. What a great little jem of a external enclosure. I've loaded mine up with affordable 1tb ssd drives in RAID1 (a total price of around $250), for a VERY SAFE storage solution. Speeds are some of the fastest I've ever seen for a RAID1 setup at ~380MB/s for compressible data. Drives are easily read outside of the enclosure - no special formats or filesystems. Solid unit, runs off USB power. Using Windows 10.

Rating: 5/5 Thank you OWC! August 5, 2019 This drive is an excellent performer for those who want SSD performance at a reasonable cost. The main concern you should have if you want the maximum speed that this product offers is to have a Thunderbolt 3 port or a USB 3.1 port on the computer you wish to use at the higher speed, many older machines will need a way to utilize USB 3.1, maybe there is a way to convert TB2 to USB 3.1 but I do not know of any at the moment, nor do I see any internet solution... Reason being, you get basically double the speed of a standard USB 3.0 SSD drive! Wonderful Value for $70. I intend to use this drive for Music Recording and Video work on my 2018 Mac Mini, it runs like a champ hooked up to one of the thunderbolt ports.

Very good write speeds, and the RAID 1 capability gives me great security against single drive failure. It also comes with a comprehensive suite of backup and maintenance software.

Rating: 5/5 Great product and Great Customer Service June 29, 2017 I received an email yesterday about the garage sale. I saw the drive enclosure. There was only one available. Ordered yesterday morning and it arrived today at noon.

It was easy to setup. I added my own drives.The enclosed instruction sheet said that OWC software should pop-up. It didn't. I formatted it using Disk Utility. All set for Raid 0. Ran speed tests. Great results.

Reviewer: lastcookie Location: Sarasota Age: 55-65 Experience Level: IT Professional Owned Product: over 6 months

Rating: 4/5 Very good - one portability issue June 7, 2017 This is a very nice, compact, raid solution. The case is very well built and performance is excellent. My only criticism is the power switch: it is very tiny and recessed making it a real challenge to reach behind and get a fingernail to catch it. No fingernails and you will be reaching for a tool to power it down.

This is only an issue, IMO, if you plan to move the drive frequently, which I do. Since it is described as being portable I think this is a fair criticism. With a more accessible switch this drive would get my 5 stars,

Rating: 5/5 Excellent quality and performance March 8, 2017 I wanted to buy a drive that can perform faster than 5 Gb/sec. This USB 3.1 gen 2 device does just that.

I've tested this in macOS Sierra. The Apple drivers in Mac OS X El Capitan do not support 10 Gb/sec.

I've connected this device to a AlpineRidge Thunderbolt 3 controller. No issues there.

I've connected this to a ASMedia 1142 PCIe card from Startech. Half the time, System Information.app would say the speed was "Up to 480 Mb/sec". When this happened, the drive performed at USB 2.0 speeds. The other times, it says "Up to 5 Gb/sec" but the benchmarks I tried showed that it was doing more than 5 Gb/sec. Windows 10 had similar issues, but would sometimes show the connection as 10 Gb/sec. I tried two different USB-C cables (one was a Thunderbolt 3 cable). This may be an issue with the ASMedia chip in general, my PCIe card specifically, Apple's XHCI driver, or a combination. I only have one PCIe card and this one USB 3.1 Gen 2 device to test.

I used Black Magic Disk Speed Test.app to test the speed. This will get you some quick ballpark numbers:

USB 2.0 speed: 41.5 MB/s Write, 41.8 MB/s Read USB 3.0 speed: 411.2 MB/s Write, 428.0 MB/s Read USB 3.1 Asmedia 1142: 710.1 MB/s Write, 784.3 MB/s Read USB 3.1 AlpineRidge: 756.3 MB/s Write, 836.5 MB/s Read

Those numbers were from a Skylake PC (4.6 GHz). The USB 3.1 speed was slightly slower in a Mac Pro 2008 using the Asmedia 1142 PCIe card: 660.3 MB/s Write, 740.5 MB/s.

For the SSD's, I used two 1.0TB Mercury Extreme Pro 6G.

Reviewer: shortimer Location: Ellington, Connecticut Age: 55-65 Experience Level: Power User Owned Product: 1-3 months

Rating: 5/5 RAID done right (USB-C) February 1, 2017 Another well designed product from OWC. Returned two tries with a LaCie Rugged RAID 4TB, which is TB2. This USB-C product from OWC just works. The price AND speed w/ RAID is the best per gigabyte compromise available at this moment. Obviously, this is in conjunction w/ the new MBpro design that only has USB-C ports. Highly recommended, because there just aren't many/any choices out there for bus powered 220mbps speed @ 4TB of memory.
