I may be late to arrive at this party. Since I started recording with computers I've used lots of different mediums. Tape, DAT, Zip Drives, SCSI Drives, Sata old fashioned drives, eSata. I could tell you the Zip drives failed a lot. :-( And that the conventional drives were pretty reliable. I can tell you that in the old days when you pulled the plug on a DAT, whatever was recorded was recoverable but if you pulled the plug on an old Windows machine you could lose the recording not saved (same was true with the Tascam 2488). I can tell you that if you pull the plug on my current computer while recording with digicheck, you still have most of the recording, even if you didn't hit save. Why is it a risk? When you're at a bar and the band stops, there is always a risk you're about to be unplugged.
But wow SSD is something better than anything I've had before.
I've used USB SSD for Linux for years, but it didn't seem that different to me from conventional drives. It was just handy b/c it was small and light.
Why I bothered trying an internal SSD...
I record many tracks continuously for hours.
When Sonar opens the project, it has to convert all the tracks to wave forms so I can find my way around the recording. This takes time. Sometimes 10-15 minutes or more. Also, Midi is saved in the project file. When I practice, I record 1 stereo track (synth output), my guitar, and a the midi from the GR20. I record over and over and over. I count my practice time in megabytes.
When Midi builds up in a project, saving the project takes a noticeable amount of time. What I learned...
SSD over SATA2 is at least 3 times better than my pretty darn fast conventional drives. IDK what came in my StudioCat computer, but they're not weak drives.
So, to all my Forum Friends, know that a 500 GB SSD used for storing Sonar Projects is way cool. You don't need to keep everything on SSD. I still have the OS and Sonar installed to conventional drives. But for the purpose of recording big projects or even just having fun practicing without IO related dropouts (means you can keep great heaps of takes), try an SSD.
