First off, hello everybody. I have been a long time browser of the forums and toms hardware in general, but this is the first time i've ever posted.
I recently started up a web development company in my town, and with that I setup a dedicated server for hosting virtual machines and also hosting the websites for the clients. I have the server built and running now, but I want to switch it over to a raid setup. Right now, it's a JABOD setup, and I don't trust the redundancy of it for customer information and data.
My question is, what should be the best raid setup to use, to ensure minimal data loss? I was going to do a Raid-5 setup, because I had read that you can have up to 2 drives fail at once and not lose any data.
What I have, is 4 5TB wd black series hard drives (I will be upgrading them to datacenter series once the need is there for it). I want to maximize the storage space available, but also ensure that I can easily replace a hard drive when one fails. (The likelihood of multiple black series drives failing at the same time is pretty minimal).
Would raid-5 be the most efficient for me, and if so, what could I expect the total storage space to be? I have a 120gig ssd that I have as the main OS drive, and the remaining hdd's are going to explicitly be for the VPS hosting. Would a raid-5 give me 20TB of hard drive space, or would it give me 10TB of space, with redundancy? I'd also like the solution to allow for me to expand the array later on and add more space as needed.
Any suggestions would be highly appreciated.
