Diving into Solid State Disk

Now that second generation disks are coming out and the prices are getting reasonable (or with that of the 10,000 RPM disks) I thought it was time to give them a try.

I’m impressed:

  • very fast – reads are frightening
  • small – but it’s hard to find 2.5″ to 3.5″ mounting brackets
  • cool – no heat this is great for cramped cases
  • clean – no exposed circuits, unlike a regular hard disk
  • quiet – obviously but very welcome
  • would fit the Mac Mini very nicely

The unit I have is an OCZ Vertex 120GB, which is sufficient space for my purposes. I dropped it into my Franken Mac and ran XBench so I could get some performance numbers with a common base, please note that these numbers were taken after a fresh install so the disk has not yet been heavily fragmented. I would also note that this isn’t the Mac version of this drive, and as such I found the drive was very unstable with mysterious hangs and failures, but it did run long enough to get some good numbers. I now have the drive installed in a Gateway GT5676 as the primary boot disk for Fedora Core 11 and it has been rock solid and running vmware like a champ, but time will tell.

I found this article very helpful:

Now the numbers:

VMware 2.x on Fedora Core 11

VMware 2.0.1 on Core 11 won’t compile, but fortunately there’s a fix.

With a little googling, I found this thread: and to save you (and me) the time you can download the following source: extract the the source into vmware-server-distrib/lib/modules/source/ and the run install.
