Server - RAID 1 performance

I have a W2K Server, on a Dell P4-1000 with a ATA-66 38GB HD on primary IDE
channel.

The server acts as a file server and SQL Server (2000) with about 8 clientes
connected.

Wondering what performance impact a (itself) mirroring RAID 1 solution has.
(minor, noticeable, heavy.....). Would plug the secondary HD on secondary
IDE channel

From users that really tested it!

Thanks

Can't say that I've tested this, if you're referring to software RAID. I use
hardware RAID for all servers I build....it is a *lot* better (and I use
ultra SCSI drives on servers, never IDE). No resource load on the operating
system (which runs, blissfully unaware of the underlying disk/RAID
structure). It may be too late for this server unless you wanted a total
rebuild, and I realize I'm not addressing your specific question, but
thought this might be helpful for future builds if nothing else. Just my
$.02.

You don't say if this would be a hardware or software solution, so I'm
guessing software:

I would say noticeable, especially if you have anything else connected to
those IDE channels. I've been running software mirrors on SCSI systems, and
it is noticeable in this environmet as well.

Well, yes, I was talking about a software config. Currently I run two
servers in two small offices with ide drives, always on 365 days a year,
rarely they brake (generally every 3 / 5 years). Quite affordable and
reliable, definetely not mission critical.

In that sceanrio I thought that a cheap sw implementation could do. But hate
performance degradation.

Could go for cheaper ide RAID solutions....???

That is a possibility, but check the software tools that should come with
your hardware IDE RAID controller. Some controllers does not alarm you when
a disk failure occurs, leaving you with a secure feeling until the second
disk also fails.
