RAID 1 and Reliability
At my small business office, we currently use a Dlink external NAS with an FTP server built in. I have it set up with RAID one on 2 HDD's. It's a so-so systems for our needs but cost-effective. Currently, my computer outputs all CAD/3D files for our architectural work and through NTI shadow, my "work" folder gets copied continually (although it doesn't work, so I have to manually start it) to the external NAS. On the other two computers in the office, they work directly off of the NAS. I don't really like the solution since only one person can work on a file at a time and if it crashes, they lose all their work since they usually forget to save the copy their working on to their desktop. And now that I've gone a little bit off track, I'll get to the point. How reliable is the RAID 1 on the two HDD's? If one fails, I understand the other is a close and it's hopefully as simple as a hot swap. But if one STARTS to fail, wouldn't the other clone its missed files or clone its errors as well?
