I am tossed between 2 lovers it seems.
I have an Utra wide Scsi2 card and I have SATA built into my mobo.
I dont do alot of high end photo/graphic or much of anything else, but what I do do (hehe my 2 year old would laugh @ that too) is play games. What is a good fast setup between SCSI, SATA, or IDe. I was thinking SATA raptor dirves. Size isnt as important as $$. I have IDE drives for storage.
 
For the most part, IDE, SATA and SCSI will give you about the same performance in games. Since games are usually not disk intensive you won't normally notice a big difference.

If I had the money I'd go with a Raptor for my main drive. Then again, if I had the money I'd go with SCSI just for every little bit of speed increase I could get. Sure, I wouldn't need the speed SCSI provides and for the most part it would be wasted. But it would just be damn nice to have.

In other words, if money isn't really a concern, I would go for the newest Raptor.
 
well $$ is a concern. I was thinking of a SCSI on my main drive. MAybe a raid configuration. And make them kind of small.
How many drives can I chain on scsi? I was thinking of like 4 9gb SCSI's they are pretty cheap.
 
If I remember correctly, Ultra Wide Scsi is 40MB/sec and Ultra 2 Wide is 80MB/sec. These scsi drives will have more data integrity features, but in pure speed they are slower than ATA100. I would get a SATA Raptor or even a good fast ATA133 drive before I would use older scsi drives as they can sometimes be rather disappointing.
 
The other thing is... A RAID-0 array of 4 drives is just asking for trouble....

Those are theoretical maxmimums. Drives don't come close to those limits.

Look at storagereview.com. The fastest SCSI drive on the leaderboard is an Ultra320 Fujitsu unit, and it tops out at 78.6 megabytes a second. The fastest SATA drives are 60-some megabytes per second. SATA is rated at 150 megabytes per second.

Check out the interface comparison at that same site.

If cost is a concern, I think you should stick with SATA for everything. Sell your SCSI controller on eBay.

You don't mention what kind of SCSI interface you have; you might be limited to 7 devices, or 14 or 15. It depends on the controller and the interface type.
