Testing Setup

I will be testing the Enyo using the following hardware:

Intel Core i5 661 Processor
EVGA H55 Motherboard
Noctua NH-D14 CPU Cooler
Crucial Ballistix Tracer DDR3 2x 2GB
Western Digital SiliconEdge Blue 64GB SSD
StarTech 2 Port PCI Express USB 3.0 Controller Adapter Card
BFG 550 Power Supply
NZXT Premium Cables
Corsair Obsidian 800D Case
Lite-On Optical Drive
Windows 7 Home Premium 64-bit

Benchmarks used include the following:

ATTO Disk Benchmark version 2.46
CrystalDiskMark version 2.2
HD Tune 2.55
SiSoft Sandra Lite 2010 SP1d
AS SSD Benchmark 1.5.3784.37609

I normally test solid state drives as the main operating system drive in the test rig but since this is a USB 3.0 device, I decided to test it as we would any other USB 3.0 device, that being a secondary drive in the computer.

OCZ provided me with a driver to use with the Enyo during testing. It's important to note that the drive is plug-and-play but you will see the maximum transfer speeds realized when using this driver. The driver is from MCCI and is labeled as Evaluation Software. As of writing, I was not able to locate the driver on OCZ's website for public download but I was told it should be on their site once the drives start shipping (they are pre-order as of writing).

That being said, I will be benching the Enyo both with and without the driver installed. My reasoning for this is that most users would install the driver on their home computer / notebook but not on other computers they may happen to use the drive with, for example a friend's computer or in a school computer lab.

The final note I want to discuss before proceeding to the benchmarks has to do with those who will be using an add-in USB 3.0 adapter card like the StarTech I am using. I discovered during testing that the add-in controller card needed to be installed in my x16 PCI-e slot (PCI-e 2.0) to achieve maximum bandwidth. When I moved the card to the x4 slot (PCI-e 1.0), performance dropped nearly 100MB/s in some of the benchmarks. I just wanted to point this out to anyone who will be using an add-in controller card with the Enyo or any other USB 3.0 external enclosure equipped with a solid state drive.

Let's move ahead and check out the benchmark results.
