I am a firefighter here and we have been using the Scott 4.5 and Scott 50 here for years. We have over 50 packs and 150 tanks in service. Here are the answers to your questions:
They are labor intensive. Hydro every 3 years, visual biannual.
They are fragile- when exposed to chemicals, they can fail
They are 4500 psi tanks.
The 30 minute tanks are 45cuft, the 1 hour are 90cuft.
When wet, water gets between wraps and can separate the laminations.
As far as the failure that Detroit had, if it is the same one we got the safety bulletin on, the tank had been exposed to a caustic chemical, and placed back in the truck. We have had no problems in the six years we have used them, and I love them for firefighting. But, they are not suitable for SCUBA.
