Thanks... Looks good.

I guess this may be a more expensive investment than I originally thought.

they are expensive... If you stick to the onboard as long as you have the latest frivers you should be able to get decent #'s.

I'm getting 8.3ms for access, 269mb/s for burst, average read 151.7 mb/s

Onboard is fine for RAID 0 and RAID 1. If you want anything more complicated then that, you'll probably have to shell out some money to make sure it works correctly.

Note that if you want RAID 0+1, and are unwilling to spend $300 on the controller card, I recommend setting up TWO arrays.

RAID 0 for game installations/windows, RAID 1 for any important data (word documents). The reason I say this is, fakeraid w/ RAID 0+1 might crap out if 1 drive fails, which means you don't get the real protection of RAID 0+1 (which can tolerate disk failure(s)).

I want to do a RAID0 with 4 drives.

I haven't ever had harddrive failure so it is not that big of a concern to me.

Plus all my important data (school work, ect) will be on my laptop.

All right, Onboard will handle RAID 0 just fine, so go for it. I do recommend getting all new drives though. Don't mix old ones and new ones, since you lose everything if any one fails.

I am really think about investing in the following:

Areca ARC-1210 for $319.99 or perhaps open box for only $260.99 (what do you think?) Here it is for only $285.99...

But do I really need a $300 RAID controller for a 2-4 drive RAID0 array? How much faster / safer will it be?

Then for the HDD's I cannot make up my mind between

4 - WD360ADFD (36GB 16MB 10,000RPM) $99 each
2 to 4 - WD740ADFD (74GB 16MB 10,000RPM) $140 each (after rebate)
2 to 4 - WD1500ADFD (150GB 16MB 10,000RPM) $170 each (after rebate)
4 - WD2500KS (250GB 16MB 7200 RPM) $68 each

All have free shipping.

Drive space really isn't an issue as I have not even used half of my 74GB Raptor yet. Speed and Price / Performance is my only concern.

I will also have to get a new PSU. That will come in the form of a PC Power and Cooling 750 Silencer...

Any insightful thoughts?

As a further note... Will the PCI Express interface of the RAID controller negatively effect my video card?

If performance is what you need and not diskspace, go with four 36GB Raptors.

As for PCIe, it will not be an issue at all. With 8x PCIe, you have a dedicated 2 GB/s bus which is more than enough. Definitely do not get a PCI card since most desktop motherboards are limited to a 133.33 MB/s shared bus.

Someone recently posted their results of a dedicated smart RAID card. I believe they were getting 200MB/s with some normal HDs (not 7200.10 or Raptors).

EDIT: Here it is. He is getting over 200MB/s with RAID5. RAID0 would even be faster.

It's a difficult choice as so many add-in RAID Controllers simply do not perform that much better than the on-board controllers .. do not discount the power of the ICHxR controllers, for what ever their faults they have they do do a job for being part on a system inclusion ... see a quick RAID-0 test with std drives a resonable 238 Mb/s Average peaking to 280...

Now is an add-in card worthwhile ... yes .. and look at PCIe as the PCI bus will be dropped shortly making any of these cards short lived for the home MB. A PCIe x4 is prob. more flexible as this is generally has wider availability across MBs, though the higher end ones do shipp 2 x16 1 x8.

On board memory and CPU help improve performance, hence this is where the costs come in .. the Areca are a noteworthy brand, another to look at would be the Adaptec range ...

Think about what drives are to be used, are there any SATA 150, if so , make sure the controller can support the lower speed as some maybe optimised to support only SATA II .. and what of SAS support ? Maybe a required option later on.

The GPU and PCIe bus OCÃ*ng will depend on which onboard controller it is on but generally you can OC this bus up around 110-120 without loosing your RAID.

I am in the same situation looking for a controller that will support some drives in various RAID arrays which the current onboard controller does not do so well or at all in some cases, due to features being turned off.

Thanks for the thoughts.

This is what I can expect from the Areca ARC-1210 and Raptors:



http://www.gamepc.com/labs/view_cont...150raid&page=1

Those incredible burst speeds are 100% a result of the ARC-1210. My 74GB Raptor only gets 120MB/s burst.
