Well I think the answer is it depends. I think his point is that ssds are way faster, faster than your SAS RAID 10 most of the time. They really are more expensive for bulk storage, and don't have the reliability of a traditional RAID set up, but that's not necessarily a problem. Most of the time (hopefully always) your data is backed up elsewhere frequently and your have some redundancy by way of master/slave servers and load balancing. If that's the case, using solid state drives will wipe the floor with traditional magnetic disks at the cost of some reliability (assuming you buy server grade drives they're still reliable).

I'm almost sold. Are you saying it is ok, or even recommended to build a web server with SSD's only?

I have also found that in deference to their claims some of the SSDs are SLOWER than regular enterprise drives.
I believe this new technology leaves a lot to be desired.

I have a question about SSDs. I've read that they like the USB thumb drives can be written to a certain number of times before they fail. What is the expected lifetime of an SSD? They're terribly expensive if they're only going to last 2 or 3 years.
