Can anyone shed some light on this. Got the Asus p5k permium board and was running 2 x 200GB in a raid0. Min was 85mb/s, max was around 125mb/s an average was 100mb/s.

Destroyed raid and created a new volume with 4 x 200GB's. And my average has gone upto 115mb/s!! WTF!! Max read 144mb/s.

Stripe is 128k. 4 x maxtor 200GB's. installed INF drivers on Vista 64.

Install Intel raid manager application, enable the write back cache option in the advanced options panel.

I'll let this one speak for itself.

CPU usage 38% :eek:

SSD, as its constant. ?

2Gb volume. must be ram drive?

I changed block size to 64gb and hit 208mbs/peak and 145mb/s average. Looking better.

Everything loads quickly.

And then you get the bill.

From those results it looks like you've got a bottleneck somewhere, you'd expect the performance to drop off, so maybe it's lower at the start than it should be.

I know what you mean, but I think its its exactly what I expect for 3 36gb 15KII's without cache 2 gets 175. I have 8x36GB in my system 2x73GB 15K II's all the scsi's together off two contollers. Most are in raid 10 far quicker than raid 0 access wise with redundancy.

With 2 raptors in raid 0 they just dont cut it though for mutlitasking as well as the scsi's.

finally decided to get my drives and build my media/storage server.

4 x 1TB Western Digital GP RE2 FYPS
Perc 5/i flashed to LSI 8408E SAS + 512mb cache (from ebay for 2 pounds

)
DFI NF4 board

very happy with the drives, performance is pretty good considering the drives green specs and the fact theres only 4 of them initially. speed isn't my primary concern hence the GP RE2 drives - reliability, scalability and acoustics is most important for my needs with this project.

raid 5 array was built in ~4hrs and they're more quiet than my single 7200.10 (quiet batch).

tweaked stripe size and some other things, even better now

Which Dell controller are you using? I've got the Perc 4e/dc and can't get above 165MB/s irrespective of number of drives

-=Vect0r=- · 24 Mar 2008 at 20:09

WD Raptor 150GB and WD 1600JS 160GB

I Have both the Perc and the Lsi 320-e they are both set to write back on no read ahead and direct io. PM if you want further help k.

looks awfully slow for a 4 disc array your average read on 1 drive is only 50mb/s

Hence why I'm getting a couple of single platter Sammy F1's (320 GB) to replace them.

6 disk Raid 0 array on an ICH9R controller. I was expecting better tbh, I might try a different stripe size.

Tiger33 · 27 Mar 2008 at 08:49

is it possible to change the stripe size without losing all data in raid 0

No but you can use Acronis True Image to create an image of the array, recreate it with the new stripe then restore the image.

What HDDs are you using in this setup?

Thanks

im using 128 for my stripe is that good?

i do a lot of compressing and rarring of large files - will 128 work best for me?
