It seems that every-one loves posting polls... so how about another discussion instead. In discussions on things like religion, everyone has an opinion because everyone is their own expert and it is based on a lot of opinion.
How about something that everyone isn't an expert in. Something that relates to computers that may require a little research, that will help us to learn more...
This discussion is on RAID devices. Do your homework.
What is RAID and what is the best type of RAID for an application that you would most likely use and why?
We use RAID 5 for a 500 Gig virtual disk that provides video recording and assesment storage. With this equipment, we needed the ability to replace a bad drive and have it rewritten to retain our video recording data.
RAID 5 utilizes parity and striping over multiple drives and has excellent read performance. For us, it was the ideal config to suit our needs.
