I've been meaning to write this up for a while, but not too long ago switched out the hard drive in my Cube for an SSD. I know many folks would wonder why go to the trouble, but as often the case, with machines we love upgrades often don't make financial sense. That's never stopped me, though(within reason). Cubes are also know for serious heat problems, and the combination of an SSD with a base fan has really helped cool mine down a lot. Initially, I tried to use a standard 2.5" SATA SSD, but the IDE-SATA adapters I had would not fit in the Cube. Instead, I decided to go the mSATA route. I started with a 2.5" IDE mSATA enclosure-I've used several of these in Powerbooks, and like them because they duplicate the form factor of a 2.5" drive. Here's the inside of the enclosure, along with the 128gb mSATA drive that's going in it And the drive mounted in the enclosure Then the enclosure closed up And mounted in a 2.5 to 3.5" bracket, along with a laptop to desktop IDE converter. There are several steps in here that I didn't photograph, but I initially installed the drive in a G4 tower and booted the tower in Target Disk Mode. I connected the Cube to it, and used Disk Utility to set the drive up with two equally sized partitions-one for Tiger/OS 9 and one for Leopard. I cloned the current drive in the Cube(Tiger and OS 9), and ran the Leopard installer from the G4 tower. It was then time to take the Cube apart, and put the SSD in it. The Cube was disassembled to remove the hard drive Then the SSD in bracket slid in Mounted, and reattached And the Cube put back together All said and done, the install didn't take too long, and provides a noticeable speed improvement for the Cube. The maximum sustained write speed I was able to get was 58mb/s. I've noticed in Powerbooks with an ATA/100 bus, these adapters seem to max at 92mb/s, so it seems as though the adapters have a pretty consistent "overhead" of about 8mb/s. Even so, it's much better than IDE Platter drive I've ever used. If it weren't for the base fan, this cube would now be completely silent-I don't guess I realized or appreciated how much noise the hard drive was making.
