Hello Everyone,
I am a bit of a computer enthusiast, but RAID has been somewhat of a mystery to me for the past couple years. I do a lot of video production and motion graphic animation, so my hard drives are constantly being taxed! Speed is another issue -- I need fast access times because I need the clips (Sometimes 30-40 gigs) to load quickly so I'm not always waiting on my computer. I've pretty much decided that I need some kind of RAID array, but I just don't know which one.

I would prefer it to be external, because I don't want to put anything else in my case because I'm already having heat issues. I would really like to know what kind of Raid you think I should setup, and if you have any places that I can go to learn how to setup an external Raid that would work best for me. Also, I know I would like to have a RAID array for all of my video stuff, but do you think I should go with one for my OS and Programs as well? That one would have to be internal of course. What do you think?

Here are my current Computer Specs:
Antec P180b
Thermaltake Toughpower 750watt PSU
evga 680i MB
Intel Q6600
Kingston 4gb DDR2800
Geforce 8800GTS 640mb
160g Raptor -- OS & Program Files
2 x 500 SATA2 Seagate Barracuda

Most people use RAID for one or more of the following reasons.

Speed
Redundancy
Volume size

It sounds like you are wanting speed, which would be RAID 0 but be aware it offers no redundancy and you lose everything with the loss of 1 drive. Is it possible you could use a RAID 0 array for what they call "scratch space" and then store important files somewhere else?

I have just given you 1 possibility for using RAID in your system there are many many more ways to setup RIAD and even with each RAID level there are multiple ways to setup a system.

Before jumping into RAID you really need a budget in mind. For instance a good RAID controller such as LSI/Intel, 3ware, Adaptec, is going to be expensive. If you want to explore an external RAID setup normally called a DAS (direct attached storage). You will really need to do some reading. There are several way to do this.

If I knew more about your budget I could do a little better with helping you.

Thank you for replying rozar -- my budget is under 800 if possible.

Is there a Raid configuration where you get speed and insurance? I might be asking for too much aye?

RAID 0+1 is the way to go for speed and security, but I've never actually set it up for myself, soooo yeah. Best bet is to do a search on RAID 0+1 and see how it sounds to you. Instead of RAID though you could just get a VelociRaptor for $300. I know that they are super fast and give RAID a pretty decent run for the money, but they also end up giving you the security of a single drive over RAID 0.

this link gives a great explanation and diagram of each level of raid

you'll probably want to go with raid 5 which will give you the best (relative) throughput and some redundancy/insurance (one drive can completely fail and you'll still be ok

hope this helps

Most good controllers are going to cost around $300-$400 for a 4 port. This will limit your budget and will almost certainly not allow you to use external storage. Have a look at this controller.

This is going to be one of the faster 4 port controllers on the market today.

You might want to look at RAID 10, Its faster than RAID 5 and is a better solution than RAID 0+1 in my opinion. RAID 5 is also a good choice but it will have slower writes and slower access times. RAID 10 will cost you 1 more drive of overhead than RAID 5 would. There are advantages and disadvantages of each RAID level and there is not perfect RAID.

At this point you really need to do your homework and make a choice that fits your application and budget.
