They arent trash, and this does not apply for Raptors ONLY. Any board running raid0, has this same risk. If something happens to one HDD, then all your data is lost. Depending on the problem, you can always use them again. But if 1 HDD brakes, the other is just fine. But how often do you hear of any HDD failures? If a HDD brakes, either way the data is lost. Remeber raid0 utilizes 2 HDD as one. So you really have 1. I have 2 raptors in raid0. My friend has been using 2 raptors on raid0 for almost 2 years. This summer me and my friend will have 4 raptors on raid0. Either way if a HDD brakes, its gone.
