Guys I really need some advice. We are doing some IP Camera installs and generally just using a Dell Desktop with a single 2TB card but we are needing to get some kind of redundancy for recorded video.

I am probably going to build a machine with a i3 processor, 4GB memory, etc.

I am looking for a inexpensive Raid 5 card that can run say 4 2TB consumer drives to keep cost down.

Normally I go with a 3ware card but hoping to get something not as expensive.

Do you have some suggestions?
 
With this small # of drives I would use raid 10 and the builtin Intel motherboard raid.

+1. Cheap card will not be better than Intel onboard RAID. So yes, go with RAID 10 - it's a little more expensive but more reliable.
 
Do not use a cheap FakeRAID card, +1 to the Intel FakeRAID, they are reliable and have backing and good software support for what they are.

Desktop-class drives are not reliable for such a RAID setup. If this data is mission-valuable or critical, you need to use nearline-class drives or low-end-server-class drives. These drives support TLER or a TLER-like function which is necessary for FakeRAID or hardware RAID controllers.

A nearline-class drive example would be Western Digital RE4 drives.
A low-end-server-class drive example would be Western Digital Velociraptor or Raptor drives.

Both are designed for 24/7 usage, desktop-class drives are only designed for 8/5 usage and do not support TLER functionality most of the time.

As far as hardware RAID controllers: http://www.newegg.com/Product/Product.aspx?Item=N82E16816103229
128MB cache, PCI-E 1x, SAS expander for up to four drives.


Now, if the info isn't mission-critical, then go with desktop-class drives and just use the Intel ICH.
