i had a single 120 8mb WD 7200rpm and would get scores right under 1000
my system is a 2.4C, ic7, xms3200c2
i bout some serial adapters and added a maxtor 80 8mb 7200rpm and ran raid 0 for 160gb

my scores are no 1500 range, iono if this is good or bad but my xp pro installed in less than 10min:)

I have 2 Western Digital Caviar 80GB 8mb cache 7200 RPM HDs in a RAID 0.

I scored a 720.... So you're getting twice the HD performance as me, somehow. What a jip. Anyone have ideas?

According to Anandtech when you use raid 0 it's faster when you have to access very large files and slower when you have to access small files. For more info read this from anandtech. Raid Reviews

Typically around 3500 but may vary since I have other things running. The number is utterly worthless so...

I scored 794 with one maxtor 40gb 2mb cache 5400rpm. With the same drive on a raid 0, I now get 1149. Is that good?

1518 with two WD400JB 8MB cache, Promise TX2000 controller. Striped with 32k stripes.

Performance depending on file size (faster with large files, slower with small files) depends on the stripe size, which determines what should be considered a "small" file and what is "large".

With my Seagate Barracuda ATA IV on the nforce2 controllers, I was getting about 870 I think.

If your performance is VERY low, check whether the cache is properly enabled for one thing. After setting up my array and installing the Promise management utility, it showed the array as having the drive caches disabled, even though the manual said it should be enabled by default. Also check whether Windows has the cache enabled, which shouldn't be changeable (greyed out). Another thing that seems to sometimes improve performance is making the disks dynamic in Disk Management, but make sure it's something that won't backfire on you before you do it; XP has issues with the way cache works that was resolved for basic disks, but not dynamic disks apparently, but it improves performance at the possible expense of data integrity.

I'd say 1149 with two 5400 RPM drives is probably pretty good.

I'd like to know how some of the scores on the FutureMark results listings were so very very inflated. 13000+? 700MBps read speeds? There's no controller in existance that can read that fast no matter how many drives are simultaneously transferring, and even 2 Ultra320 controllers combined can't get that high in real throughput, let alone whether any system bus could transfer that much data.

It would depend on your controller. Windows lists it in the properties for your array in device manager on the policies tab. This is greyed out for me, may not be for other controllers. You may also be able to download or install from CD the specific software for your controller which has the option to enable or disable cache and other settings.

I have the promise fastrack controller that's built onto my Asus P4C800 Deluxe Mobo. Yeah, when I look at my hard disk in device manager, there is a Policies tab, under which it's all greyed out and has Write Caching set to Performance

Just ran PCMark and got 2240 on 2X 80gig 8mb Maxtors SATA Raid 0 (64k blocks I think.)
Highpoint SATA converters BTW

System: SINXP1394 BO, 2.4b C1, 2X 512XMS 3500

Block size seems to make quite a differance using SATA raid on IDE hard drives.
IDE drives seem to like 32k or 64k blocks, while true SATA drives seem to prefer
smaller 16k blocks.

Here is some additional info,
as well as some additional benchmarks.

I had no choice of stripe size when setting up my raid. I believe it defaulted to either 4kb or 64kb... I can't remember which.

oooooo, i chose 128k....Abit Raid bios said use that for highest performance but shoot's score is nicer....i wonder if i can try different block sizes with out loses my data....

restoring my data right now so i can try it:(

Hey Nebor,
I just downloaded the manual for your board, and if I'm not mistaken in the Fastbuild
utility main menu (page 5-25) if you choose #3 you should be able to set (or view)
your block sizes. I'm not 100% sure so back up your files if you intend to make any
changes.

Hope this helps.

On closer inspection, I see that I have a 64kb stripe, in option three of the setup.

I found it strange that Asus or Promise wouldn't allow you to set stripe size so I
did a little searching, take look at this thread I think
you'll find it helpfull. Page 2 tells how to enabe cacheing

Acheiving high scores on synthetic benchmarks does not correspond to your seeing better throughput in day to day processing. Fine tuning depends on ones specif needs. My 64k striped array may be poorly configured when running your applications.

All drives in an array should be as close to identical as possible in order achieve optimal results.

Most onboard Promise Raid controllers are the Lite variety, meaning that the stripe size is not configurable and is set at 64k.

Each controller manufacturer has a sweet spot drive that works great with their software. For Promise it is IBM drives, Highpoint it is Maxtor.

I have to laugh at the posts indicating the user wasn't even sure what hard drives were on the controllers (at abxzone.com).

Those benchmarks make me wonder though... 900MBps transfer rates? Was the Windows cache bypassed in one test and not the second? That's the only possible way to get that high.

That "lite" thing about the controllers is asinine. It's just a BIOS thing, I can't see why they'd make a controller unable in hardware to handle changing stripe size, so I presume it's just a BIOS option that they didn't enable. It pretty much makes using such a controller a bad idea, better to get a non-RAID board and buy an external controller.

It is asinine but it is certainly not a function of the Bios. Running a stripped down on-board Raid controller is a poor Idea to begin with, running one that cannot be configured properly makes it worse.

Promise installs a stripped down microcode with their on-board controllers. Their included documentation clearly refers to the controller chip/sw as "Lite". Both the Highpoint and Promise solutions are software based.

I know they're software, but since the striping is configured in the BIOS, I assumed it could be controlled there. I wouldn't have thought they'd actually create special microcode for the chips just because they're used onboard, since they use the same chips for some of their own controllers.

It's been widely published that one can release the onboard RAID bios from the mainboard bin or rom file and add another bios that has full functionality. This includes more RAID modes, wider selection of stripe sizes, etc.

The "Lite" versions allow for two modes: performance or security. Performance is striping with 64KB stripes. Security is RAID1.
