I too have many questions about RAIDs and it looks like I am not the only one. So let's here it; what are they, plusses, minuses, should we do it or not.

The Western Digital Media Player thread convinced me to buy one so let's hear it DSF techoweenies

I pulled this over from random thoughts. If Satan wants to clean it up, cool, but if not at least it's a jumping off point.

I don't know that much about them actually. I know how mine works and i can tell you about that.

Let me take some pictures of mine and it'll help me illustrate my thoughts.

BRB...

wow, thanks for all that info. I get it now. So basically you have 3 TBs of storage but some it is used to parity some data. so technically you only have 2 TBs of storage?
I just have 2 extra 1 TB drives that i copy everything to on each drive. So basically I have 2 separate drives with copies of everything twice. I burn all my movies and then delete them so I don't need much more than a TB. I like that it could be faster for editing movies though. It takes freakin 3 hours to convert one DVD to an avi.

Basically, yeah. I am sacrificing 1TB of storage to "back up" 2TB. Don't even ask me how parity bits work. I know about them, but it's a way beyond my level of understanding. Here's the Wiki entry on parity bits.

And actually, that's probably not an accurate statement. I know there are lots of people that understand RAIDs better than me that would take issue with me saying my RAID 5 is "backing up" any of my data.

Here are parity bits as it applies to a RAID.

yes it is RAID 0

But i mostly work on TV commercials, shows, or corporate videos so i never need long term storage of data. Once the project is done i rent a DIGIbeta deck for $700/day and output it. I then hand that tape off to my client. Then i might make a copy for myself but the data gets erased.

There is no way i would need or afford anything other than RAID 0 --- it's just too expensive for what i do.

My current RAID array cost around $12,000 U.S. (thats not a typo). Granted the prices have probably come down a lot since then but i'm sure to duplicate what i have in a different RAID set-up would be cost prohibitive.

cool, that explains it for me. You need at least 3 drives to do it worth doing.
