Hello,

Is it possible to connect PCI-E x4 SATA RAID controller (for example, HighPoint RocketRAID 2220) to one of PCI-E x16 slots, or i must have motherboard with separate PCI-E x4 or x8 slot?

Callandor: Areca is unavailable, so i must choose between 3ware and HighPoint. SLI motherboards looked an option because they have 2 PCI-E x16 slots (while it is very difficult to find non-server motherboard with x4 or x8 slot).

cooljai1: yes, i knew that x16 slot can be used by slower cards. It is just unclear, if "SLI" motherboard can accept other cards that video in second x16 slot :)  Everybody talks about video, but not video+raid.

Looked at Areca site - only server motherboards tested. Still not sure if it means NO for desktop motherboard.

The problem is - i do not think, that i need server platform. Speed is not an issue, storage space is.

Sorry, found another page with continued compatibility list. The answer is yes, it will work (mostly...).

Areca is unavailable?  Too bad - it's a great card!  Using HDTune, I measured a range of 250MB/sec to 150MB/sec on a RAID-5 array I built.  A HighPoint 1820A RAID-5 array on a 64-bit 66MHz PCI-X slot only achieved 50 MB/sec with the same drives, so choose your controllers wisely.

What cpu do you have?  The DFI LanParty NF4 and Asus A8N-E have x4 slots.

No, at this time i can only choose between 3ware and Highpoint. Areca last seen was only on 2005.

CPU can be various. Right now i planned Intel 820 and (Asus P5LD2 Deluxe) SLI motherboard.
Or i can replace one workstation with dual Xeon 2.8GHz and Intel SE7525GP2 with AMD x2 4200+ system. In this case i get server with both PCI-E x4 and PCI-X 64/66 slots.

P.S. sorry for error during points split.

I would recommend the 3Ware over the HighPoint, then.  In an SATA RAID card comparison, Areca and 3Ware held the high marks: http://tweakers.net/reviews/557/1.  The HighPoint was good for its price, but not if you want performance.
