If you run WinXP, the SCSI drives will not perform on par.

Buddman:
There are few things that really *need* scsi (video-editing come to mind). I can only say that in my case, it made the system far more responsive, but you must know that I went from an old (slow) IDE-drive to a 10K SCSI. What also plays a part is that my current system still is a PII-450, and the IDE on that board requried more CPU-usage than SCSI (this is no longer the case, IDE has improved a lot). The difference between my drives and recent IDE-drives performance wise would be far less than what I have experienced.
The only other reason I can see for going SCSI, is the added extendibility: in my sytem, I'd have to few IDE-ports if my system was using IDE exlusively (2 HDD, 1 DVD (the only IDE device), 1 CDRW, 1 SCSI ZIP250, and another harddisk on the way), and all PCI-slots are filled up.
Umfriend has made a great suggestion...

Well, I will actually be using the comp for video editing for my job at Fox News. That's why I went with the AIW 9700. If I go for a 15k rpm drive, then I'll have to limit the CPU to a 2.66. If I get a 10k rpm drive, I can get a 2.8.
EDIT: Though I will be using the comp for video editing, I should add that I won't be doing very much video editing on it. Just only when I need it to save me a trip of going into Austin.Last edited by BuddMan; 14 November 2002, 06:00.System Specs:

Isochar: Why is that ? (I'm currently running W2K, in which there is a difference)

Hmm, I just found another reason to go SCSI: drive warranties ! On a lot of SCSI-drives, they offer warranties up to 5 years, in comparison to the 3 years (or sometimes even just 1 year) with IDE drives:

BuddMan, if you plan on keeping the processor for a while, I'd tell you to go with the new 3.06 P4s so that you enjoy the benefits of SMP/SMT.
VJ, this is a long discussed bug in WinXP. Microsoft has been working on a fix for the past couple of months, but no sign of it yet. Look at this thread:
*edit* To give you an idea of how bad this "bug" is - there are situations where reviewers have found 5400rpm IDE drives beating the new Cheetah 15k.3 in read speeds. :/Last edited by isochar; 14 November 2002, 06:22.Comment

Thanks, I'll read up on that thread (guess I'll postpone the move from W2K to XP a bit longer...).

Well... I _really_ think you're underestimating the amount of noise that a fast SCSI drive makes. I mean, we're talking "low flying aeroplane" noise levels here. Seriously.

Well, I admit, it makes a lot of noise, esp. during seeks. The Quantum is a lot noisier than the IBM wrt. spinning noise (whining) and short stroke seeks.
I can imagine that some people would mind, I personally don't... although I won't use my computer to watch dvd movies, and I prefer it switched of when I watch TV (a few metres away). The sound is "muffled" somewhat by the 4x80 mm fans that are cooling the case. I do intend to put some noiseblocker mats on the inside of the case, just to isolate it more.

Dunno about you, but I think that buying a good SLR camera and a film scanner is a good way to spend your money.Comment

An alternative is to go digital SLR : I'm using a Nikon D100, and it is just great fun to use. But I think you'll need more money than a SCSI-setup...

On the XP/SCSI-issue...
Is this the definite solution ?
Or is the SCSI-performance still not at maximum ?

Given the current speed of IDE, I think the only reason to go scsi is expandability/flexibility.Yeah, well I'm gonna build my own lunar space lander! With blackjack aaaaannd Hookers! Actually, forget the space lander, and the blackjack. Ahhhh forget the whole thing!Comment

VJ: It's still not up to par.
MS has supposedly "fixed" the problem in SP1... but people are saying it still isn't all that.
And this goes for IDE-RAID as well, since that enumerates as a SCSI device.
I hear it's MUCH better with SP1, but still not as good as in XP.
And heed Dogbert's advice - the noise coming off a 10k drive is just obscene.

Gurm:
Ok, thanks for confirming... There are some threads over on 2cpu on the subject, and they also confirm it is not up to par (70%-90% performance)...
Is there any known cause (certain chipset, controller, ...?) ? Or does it just always occur ?
(I should think there are XP-servers with SCSI-disks out there)
