I am probably overseeing a similar number (3-4000) of Hitachi A7K3000s, A7K2000s and WDC RE4s and I probably see a few failures a month. When we are building a new machine and we get a fresh shipment in, maybe 10% failure rate right out of the box. Those that survive the burn-in usually do pretty good. Man, you have my sympathy with that failure rate in excess of 50%... even the WDC Greens weren't THAT bad (although it probably got close, as we neared closer and closer to EOLing them... and they had been moved to third-tier "backup storage" status by that point). Thankfully they are gone now, LOL.
You're right, esp. in large installations, it's critical to do your homework on drives, pick a good candidate, validate it and then run with them. Even with the good ones, you've gotta keep a watchful eye... "when you buy them in bulk, they fail in bulk".
