The Mac Pros are very powerful machines, and their design won't ever make you ashamed of the animal below(or ON) your desk. The Mac Pro has always been a great rig to own, even back in the day when it was known as the Power Mac G5, and used the PowerPC 970 CPU. Anyway, today they are using Intel processors, just like the other Macs Apple has in the portfolio, but one thing has been missing in the last years - a Blu-Ray drive. The good part is that now, this issue has just been left behind!

Currently, the Mac Pro computers available feature one optical drive, the 16× SuperDrive (multiple DVD write formats), and to be more accurate, the Pioneer DVR-111D or Sony DW-D150A are the only choices available. Fortunately, a second optical drive is optional. Thanks to MCE Technologies, the Blu-Ray for Mac is finally here!
Since the name is not quite an original one - SuperDrive...another SuperDrive? Well, that could surely cause some confusion! Why not...BlueDrive? Well, whatever, let's see what this beauty can do, apart from - as you can see in the picture - being blue, shall we?
Able to burn 25GB single layer and 50GB dual-layer Blu-Ray discs, the MCE Super Drive features 6X Blu-Ray write speeds and 16X DVD recording speed. It fully supports Lightscribe, and can play both Blu-Ray and HD-DVD media.
All fine, until we get to the painful part of the whole deal - the price. I know it comes with Toast 8 Titanium and a 25GB Blu-Ray rewritable disc, but a SRP of $699??? Not my thing, thank you! Anyway, I am sure that, if you really need a Blu-Ray unit on your Mac Pro, $699 won't be that much, after all, but for me, the DVD is still the right path to follow.

Meanwhile, Blu-ray drives and burners have become cheap. If cheap and fast 25 and 50 GB backup disks are what you need, why not get one now. I used a LG BH10LS30 but there are others. Installing is easy, in contrary to what some say about aftermarket sata drives. Here's how I installed a Blu-ray burner in my Mac Pro;
