The scale of the Windows 7 Experience Index ranges from 1.0 to 7.9. After some recent tuning I got my system scoring 7.3, except hard disk, which is scoring just 5.9 (base score).

Altough 5.9 is a decent score I'm seriously considering going RAID-0. For US$ 90 I can get another identical HD. How much do you think performance will increase with 2 disks in RAID-0?

Windows Experience Index before tuning

CPU @ 3.06 (+27% oc'ed) and GPU @ 625 / 993

Windows Experience Index after tuning

CPU @ 3.40 (+46% oc'ed) and GPU @ 675 / 1100

WEI is unreliable at the best of times and shouldn't be used for any serious benchmarking. As a quick guide its OK.

Mine is 6.9 and falling. Every time I run it, I get a lesser score due to this shitty OCZ drive and erratic WEI, started at 7.2, have now given up.

You won't see any speed increase unless it's a dedicated RAID card you'll be using. I'm using RAID0 on crappy Intel RAID and I get the same 5.9 in RAID as I do in non RAID. Then again, my drives are at least 4 years old ....

I found a lot of free HD bench tools here: http://www.benchmark...ml?/be_hdd.html

HD Tach 3.0:



I'm disappointed at RAID, at least on-board solutions. Note the performance comparison between my 500GB SATA2 HD (red) to an Intel controlled RAID-0 w/ 2 250GB 7200rpm HDs (blue).

Better forget the RAID thing for a while... Maybe in my next build I put a dedicated card.

Thanks for your inputs !

actually the win7 winsat test is pretty good. i would use it above other benches.
rik, i think it's the carpenter, not the tool, that is having issues...

i get an overall of 7.8 with a card, and using my south bridge, get 7.9... this, however, changes when doing specific portions of the winsat/atto 2.46/everest, etc.

here is a win7 winsat with an LSI card and four ocz ssds, raid0:



and an atto (version 2.46):

I think so. The results are very close to those of HD Tach and other benchs.

Winsat - seq. read: 86.92 MB/s
HD Tach - seq. read: 85.40 MB/s
Winsat - seq. write: 56.38 MB/s
Quick Bench - seq. write: 56.25 MB/s



MO, what's you opinion about on-board RAID controllers? Is it worth to go RAID-0 with an Intel controler on ICH7?

[m.oreilly]

sure, as long as you can use the intel storage manager app (manages the array, allows write back cache, etc.), though i'm not quite sure how many pci-e lanes/bandwidth the ich7 has.
