Alienware packed in three 7,200rpm 500GB Serial ATA 3GB/s drives, each with 16MB of cache, in what might, at first, seem like a curious arrangement: Two are used as the system drive in a RAID 0 configuration while the third, termed the storage drive, is configured as a standalone SATA device.
In most systems, only one would be used as the system drive and two as data drives, because of the performance advantage RAID provides. However, RAID characteristics can differ from motherboard to motherboard -- in almost all cases, recreating your RAID array will mean you'll lose the information the drives contain. So should your MJ-12 8550i go down in flames (so to speak), you can simply pluck out the single data drive, install it in a new PC (or mount it in an external drive case), and recover all of your precious data.
Other features include 700 watts of power; a maximum memory capacity of 16MB, and room for a fourth hard drive. Dual Gigabit Ethernet ports are provided, as are six USB ports (four at the rear, two up front). Two Firewire ports, and front-mounted mic and headphone jacks round up the external connectivity.
Alienware has taken the hassle out of having a door on the front panel of the box. On this case, the door is mounted to a hinge that opens and then slides back out of the way, flush against the side panel, if you wish to leave it open. It’s completely clear of errant optical disc trays or knees. Internal sound-deadening material keeps things surprisingly quiet.
Do You Need All This Power?
So should you run out and buy this computer for your workplace? Well...maybe.
As with all multi-core systems, it depends on what software you’re using to drive it. Running single-threaded programs on it is a lot like using a racing car to drive to the grocery store.
In general, most software built for the average desktop system today still doesn't fall into the multithreaded category. Even simple video rendering runs about as fast as it would on a Pentium D 945-powered computer because only one core is being utilized (Ulead VideoStudio and most video rendering applications written for current desktop PC platforms are single-threaded). As you make the rendering more complex (by, for example, changing video bit rates from the original) some small part of another core might become active. Continue to ramp-up the effects (overlays, titles, etc.) and you bring more of the computer's cores online.
It's when you move upstairs to more complex enterprise applications designed to run across multi-processor systems that you start to really use the MJ-12 8550i's potential: CAD/CAM software, database applications, and the like.
And, of course, there are games. When I ran Supreme Commander, an RTS game that takes advantage of multiple cores, the MJ-12 8550i did noticeably better than a single quad-core system with dual 8800 GTX cards in an SLI arrangement. (Of course, the MJ-12 8550i costs about $2,000 more than the competing system.)
In short, Alienware's new business system is a very fast but specialized (and expensive) tool geared toward graphic artists or animators running multithreaded software, enterprise shops running virtualized environments -- and yes, hard-core gamers. Unless you fall into one of these categories, you may lust after this bleeding-edge system, but you'd be better off with a more practical box.
