I don't. Like I said, I'm an engineer and numbers actually mean something to me and others like me.
At the risk of repeating... I gave you actual numbers (sustained transfer).
You can match typical SSD drive speed (about 250MB/Sec on reads) with a pair of fast conventional 1TB HDs in RAID-0.
Even if you "Short Stroke" the RAID array (to maintain top speed), you still have far more storage space... with the same sustained read speed... for about $120. This said, in small form factor applications, this isn't an option.
To get those kinds of read speeds, SSD is the only option.
As for using SSD as a boot drive vs. conventional HD...
Take the same base machine... and configure it both with SSD boot drive and then with a (important detail here) fast current generation conventional HD. (Create a backup image file of the system using True Image or similar... which will allow you to quickly swap/migrate boot drives)
Compare the performance...
SSD will open apps a little quicker... but the fast current generation conventional HD does nearly as well.
If you just wanted to argue... one could also say the burden of proof is on you to show evidence that SSD is a major imrovement over conventional HDs (as a boot drive). As you say... show me... don't tell me. Show the figures on exactly how much faster Sonar opens when running from a SSD.
Nobody is saying SSD isn't technically faster...
We're just stating that the difference isn't super significant.
Once the size/cost ratio moves closer to conventional HDs, we'll all be using SSD.
