Raid 5 Write Speeds

[imported_ghostshell98]

Can someone help me out,
Below is a screen cap of my write speeds for this raid 5 setup , it is taking for EVER to copy files to it. as you can see it is chugging along at 5 to 7 mbs per sec. It has taken 10 hrs to copy 200gbs and I am very unhappy with this.

here are the setup specs
winxp pro
p5wdg2-ws pro 975x pci-x card megaraid LSI SATA 300-8X with latest firmware
Raid 5 64k striping 3 drives=WD7500aacs GP drives with wdtler enabled

I cant live with these pisspoor speeds , is it my controller , my mobo , or my drives??
should I ditch the card and get an ab9pro or similar priced ich8r mobo to run raid 5 from ?? would I get better write speeds using software raid 5 ?
Thanks

Any numb er of things can cause this, you sya you have checked and you have the latest firmware so thats a good first step. Is the cpu getting pegged during the file copy operation? Have you updated the drivers along with the firmware?

As for your other questions, yes you would likely get better speeds from software raid, but the problem is its going to peg your cpu so it wouldnt be a good idea. Also with your stripe size if you copy lots of large files then set the size to the largest you can get, if lots of small files then smaller size. This wont make worlds of difference but is a nice tweak when everything is setup and working well.

i hear the arc-1220 has really good write speeds but it costs a buttload

RAID is definitely one of those instances of "you get what you pay for".

You could try disabling TLER, just in case it is misbehaving and causing constant reconnects for your drives.
