I think your graphics card is your main "bottleneck" as you call it. Go sli or get a new card.
I am looking into a new card now. I am thinking 2 8800GTX's in SLI. But like I said, I do not do a lot of gaming. But 3d modeling take a serious video card. Especially when it is on Dual 22" monitors at 1680 X 1050. Many times with two different objects at once but sometimes one object on multiple views.

I'd highly recommend a dual GPU card here instead of two cards. It's gonna be pretty cramped in there with already one PCI-E slot taken up by the RAID controller.

Chozart, do you have first hand experience with the setup you mentioned? If so What card was used?

Also, I just cannot see 4 SATA drives in a RAID 5 keeping up with two 15K SAS drives in RAID 0.

It Seems like the SAS drives would be a lot more responsive also.

As for the Raptor, they are TOTALLY over-rated. 7200.11's from Seagate are proven to kick the crap out of Raptors in almost every aspect expect stuff like seek time obviously, and they are much quieter, cooler and cheaper. 32 megs of cache has my e-peen jittering too.

4 way RAID1 of 7200.11 should be PLENTY enough for you.
Sorry, quick question. What would be better, Seagate Barracuda 7200.10 Perp. Recording Technology or Seagate Barracuda 7200.11?

Would one SATA/SAS controller with two internal ports be able to make 2 arrays? or would i need two cards? I will look into a dual GPU video card as it is gettign tight. However, now the only two cards I have are my video card and 802.11n card so It is pretty open.

Not first had, but second hand (Cyberdruid has the Areca controller, and I posted some of his benchmarks earlier in this thread). The SAS drives are indeed more responsive, but you stated you work primarily with large files, mostly negating the benefit of responsiveness (which is key when you work with lots of small files). If you work with small files, and lots of them, then I'd have advised the SAS solution.

Check this database here:

yes, it's for single drives... but it gives a good idea. Interesting that the Raptors take the win in the High-End Drivemark 2006

There are definately some other very interesting results... the 'lowly' WD7500AAKS comes scarily close to the SAS drives in terms of Max Sustained read.

Obviously, Ultra320 SCSI is still king.

Just to add, the Windows file system only allows up to a 2TB partition.
Once again...

I have actually never used a single benchmark, don't really get the big deal. I am a car guy at heart and benchmarks are like horsepower. Guys build cars that are "dyno queens" meaning they go for the most HP possible, and not the best car.

While most of my projects end up being very large. I am also using hundreds of small items that are imported into drawings such as trees, cars, people, ect.....

I am just trying to figure out the best solution as now my storage speed seems to be the big wall I am hitting as CAD is taking forever now.

Also, I am looking at this video card for a dual GPU card. It is about the same price as two cars for SLI.

That was indeed the card I was thinking of (video card I mean). That's a much better solution than two 8800GTX's. You have to realize that the 8800GTX is a large dual slot card, and you'd have to squeeze the RAID controller between two of those beasts. With the GX2, you have yourself that hassle, and free up room, making cabling easier.

Now, back to the hard drive issue... If you can and are willing to afford it, you won't regret goign with SAS. However, if you really want to rock, get four 74GB 15k SAS drives in RAID0, and make your backup array just a simple pair of these 1TB Seagates in RAID1 (which can easily be done onboard). 1TB should be plenty of backup space

What do you think of the controller i posted earlier?

Also, why not 4 147gb SAS drives. They are not much more expensive. It is going to 300gb drives that get crazy expensive.
