I don't currently run RAID, how much performance do you think we would give up by going to RAID 1?
RAID performance includes more than people usually think of, and has alot to do with what apps you are using. For example raid0 could be faster loading a large file to work on, but then your speed improvement may taper off if your app itself is made up of small files, reason being that while read transfer may be faster with the two drives, head positioning to find the small peices may be slower over multiple disks. In general raid0 is faster than a single disk, but for the average user the performance increase might not be as noticable as they thought it would be, where the chances of disk failure are higher with two drives (that act as one) than with a single disk. This is a good read if your interested in RAID:
(From the article) "I would also say that too many people overvalue the importance of greatly increasing sequential transfer rates through the use of striping. A lot of people seem to think that implementing RAID 0 is an easy way to storage nirvana, but for "average use" it may not help performance nearly as much as you might think."

I don't use raid myself 'cause I don't really need it (I auto back up to an external HD), and I usually only work on AD by itself. I did get a WD 10k raptor HD which I am happy with, but there again, I don't feel much of a speed gain over a 7200 sata.
The biggest bang for the $$ was my mobo/cpu. I have a DFI LanParty NF4 with a 939 Athlon 64 3000. I notice a big improvement over an Athlon XP at the same clock speed, especially in display speed. I have it overclocked to run at 2400 mgz, up from it's stock 1800 mgz. On the A64, the northbridge is built into the cpu, so there is not much need to oc the memory. I just turn up the cpu mgz, (it runs at stock voltage), use a mem divider to keep the memory speed stock (I am using Corsair ValueRam), and bam! I have an A64 3800 that runs at 34 deg C under load, idles at 28, and is stable as stock. I built this box just to run AD, cost less than $1400 for everything.
