My speeds varied from a low of 10x to a high of 28x, against a theoretical maximum of 48x. The size and file count figures were as calculated by x Speeds are rounded due to the variability in hand timing. The stopwatch was started when the Finder’s progress dialog appeared, and stopped when the dialog disappeared. Tests were run on a Dual 2.0GHz G5 running 10.4.10 and a Sony DRU-840U. X Speed is relative to a 1x CD-ROM drive (150KB/s) The results were interesting: the structure of the files and folders on a disc has much more to do with the speed of copying than does the amount of data, as you can see in the results below. I then timed how long it took to copy the contents of the CD or DVD to the desktop, starting the stopwatch when the Finder’s progress dialog appeared. Reading CDs and DVDsįor my reading speed tests, I picked a few discs out of my collection, pretty much at random. Most importantly, dual-layer burning and reading worked perfectly, which was my main reason for upgrading. However, despite the mixed results, every single result is notably faster than it would have been with my old drive. Perhaps there’s some limit in OS X relative to drive speed in general, and Leopard will address it. Perhaps the drive isn’t fully supported, and OS X doesn’t know about its top speeds. The results were mixed, and I’m not sure exactly why. To test the drive, I set about reading from and writing to a variety of media I had lying around the office. I then buttoned the machine back up, hit the power switch, and then waited to see if the surgery was successful.

After a bit of prying, though, I got the cable in place and connected. When I went to install the drive, this was actually the cause of the only (minor) issue I had: because the drive is shorter, the 90-degree bend put the cable at the wrong spot to fit through the hole in the mounting bay (which you need to route it through to connect it to the motherboard). I transferred the cables from the old drive, including the sticky tape that helps hold the connector cable in a 90-degree bend on the top of the drive. With these parts in place, the new drive now looked like this:Īt this point, it was time to put the drive into the machine and see what happened. The faceplate doesn’t quite fit perfectly-it won’t snap into the holes on the new drive-but it sits flush and tight, which was good enough for me. With the bezel off the new drive, I took both the faceplate and the aluminum shielding from the old drive and put them on the new one.
