My Raptor boot drive of 3 years went out a week ago. 5 year warranty, so I sent it in on an RMA, knowing I was getting an SSD to replace it. I didn't really know what to do with the Raptor, since it was sort of old tech. I just opened the package from Western Digital: 150 GB VelociRaptor. Whaaaaaaaaaaaat?!? I was expecting to get a Raptor back, but a 150gig VR is a pretty serious upgrade. I already replaced my system drive with a 60gig SSD, so now I don't know where I should use this drive. Seems like a waste to not throw it in the Mac Pro... or maybe use it in my MacBook Pro now as a system drive? Is there a pretty big boost from the 3.5" Raptor 150 to a 2.5" VelociRaptor 150? It came in the cool little tray adapter, so hopefully this is the one that fits in the Mac Pro slot. Very good of Western Digital to give me a VR instead of just finding an old warehoused Raptor to send me. I'm pretty pumped to try this baby out!!!
