OWC 320GB Mercury Elite Pro-AL Quad Interface

Review - OWC 320GB Mercury Elite Pro-AL Quad Interface

by , 9:00 AM EST, November 9th, 2006

Flexibility and versatility are great things to have in your data storage devices, and Other World Computing's Mercury Elite Pro-AL Quad Interface hard drives deliver. These drives feature USB 2.0, FireWire 400, FireWire 800, and eSATA connectors, Seagate's 7200.10 Barracuda drive mechanism, and an aluminum case that matches Apple's Pro-level Macs.

I tested the 320GB model, but the unit is also available in capacities ranging from 250GB up to 750GB. All of my benchmarking, except for eSATA testing, was conducted on my 1.67GHz PowerBook G4.

The Mercury Elite Pro-AL's drive ports.

Everything you need to get started is included in the box: Power supply, USB, FireWire and eSATA cables, rubber feet if you want to place the drive horizontally, a stand to hold it vertically, and Retrospect Express data backup software.

Cables, power supply and stand are all included.

The drive is super-quiet. In a normal work environment, you wouldn't even notice any sound. My desk tends to be really quiet in the early morning hours, so I could hear a faint hum. Once the usual hustle and bustle of the day began, however, the drive's hum faded away into the ambient sound.

To keep everything fair and standardized, I use ProSoft's Drive Genius to benchmark a drive's read and write speeds. USB 2.0 data transfer speeds were no better than I would expect from any other USB drive. FireWire 400 fared much better, and FireWire 800 performed even better still - no surprise there. Unfortunately, I lost my eSATA test system before I could complete my benchmarking. Based on my preliminary results, and cross-referencing other benchmark tests on the same drive, eSATA performance was in line with FireWire 800, if not a little better.

Speed in MB/s
USB 2.0 FireWire 400 FireWire 800
Sustained Read 46.76 64.25 89.23
Sustained Write 47.26 62.57 82.59
Random Read 32.42 42.73 55.11
Random Write 37.13 49.2 64.87

Even though you don't need to install any software to use the drive, I checked the included CD to see what was there. In addition to Retrospect Express, I found Intech's Hard Disk SpeedTools - A set of utilities to benchmark your drive's performance and defragment files.

I also found drivers that let you use the FireWire 400 interface on Macs running OS versions as old as 8.6. Although most users have migrated to Mac OS X, it's nice to know that graphics pros and anyone else that needs to keep a legacy machine around can take advantage of these drives, too.

If you look on the hard drive, you'll also find a folder full of shareware, Apple updaters, icons, QuickTime movies of Apple commercials, and more.

The Bottom Line
OWC's Mercury Elite Pro-AL Quad Interface hard drive is a great all-in-one package with everything you need to connect to any computer. Once you move away from the USB interface, performance improves dramatically; but that's to be expected. The fact that these drives come with all of the cables and Retrospect Express make them a great deal for the price.
