The Areca cards are faster, but the drivers are not well integrated into the mainline kernels. So, if you want easy, go with 3Ware... if you want performance and are willing to build your own drivers, then I would highly recommend Areca. My $0.02

i use 3ware

if you are using a lot of drives, i use 8-12 in a raid 5 config,
and its pci-x  or   pci-e

you are better off using the 3ware over linux RAID,
because with linux you'd have to get a expansion sata pci-x/e
expansion card anyways, and thus you may as well get the 3ware
with hardware raid 5 or even 50 built in.

3ware also have linux command line monitoring and admin tools,

also you can get battery backup modules and the top 3ware
in the line i use has a 512MB cache (with battery you can use it for
wrtie cache), and this definitely can speed things up depending on what your server is doing.

I have about 6 3wares installed now, all have been 100% perfect.
I used 3-4 promise's in the past, they are slow, and don't have decent
linux command line monitoring and admin.

I'm looking at building a SATA II RAID-5 system, and I'd like to get some thoughts on controllers since there are a multitude out there..
I'm going for either 4 or 8 ports. The rig should be run by a 10.1 x86_64 system with dual opterons.

The manufacturers I'm looking at are:

Adaptec
Highpoint
3Ware
Promise

Can someone with knowledge about these tell me the pros and cons with each of them?
