Which hard disk drive for RAID?

Hello,

 I am building a home server that will be used for running WMware, streaming movies, music, but most important, will be my backup machine. I already have my primary PC, therefore, the server will be my secondary (online 24x7x364). I was about the purchase about 3-4 hard drives and configure RAID 10 or 5. I was looking around on this site and found a valuable article about disk drives reliability, and this made me re-think my strategy on which hard drive to get. I am thinking about getting a WD RE4 ENTERPRISE drive. My question for you experts is, is this a good drive for home use and RAID? (I know it says  RAID-specific, but you know some drives have buggy issues). Can you recommend any? Also, is a RAID controller better than onboard, if yes, any recommendations? I will greatly appreciate this.

Money is a factor but I would go for quality before quantity.

Definitely. Any recommendations, as far as RAID controllers? Also, for storage, streaming and running VMs, which one is better, RAID 5 or RAID 10??

From what I've read, it appears that RAID 10 has the edge over RAID 5, if only because of the parity overhead involved in RAID 5. This is pretty debated so you'll probably get differing opinions with this. Do you have the hardware, mobo, etc. already? If so, you would narrow the selections to what works with what you have and narrow down from there. I find myself reading Newegg reviews for good feedback regarding such (as a pretty decent resource for hardware reviews...at least for me).

dlethe. thank you for your response, and such good article. I was looking at the LSI controller in the site you provided. They seem to be the real deal. However, when I checked in NEWEGG none of them have Windows 7 support, and there are many people complaining about compatibility issues. maybe they don't know how to configure it at first, but still, will this be an idea controller for my Windows 7 x64 machine?

again, thanks for your assistance. yobri, dlethe.

it is imperative to get enterprise class drives, due to the error recovery timing constraint.  Most people either don't know or figure they know more than the people who designed the controllers so blow it off.  

Go to the LSI site and look at the download sections for support for any specific O/S, not newegg.

Remember also, that the people who use the right disks and don't have problems is the norm, and those people will never go to a website and complain that they have problems :)
