Good to hear everything seems to work out. Sorry i didn't respond earlier, but it's my holliday hehe Let me know if you get it running ok, and if you got problems running ATTO bench contact me, it's verry simple. ( don't forget to set it at 32MB, and it's ok ) Ohh, ps. Indeed this function is a piece of code identical to the server versions of windows wich does have standard raid 1 and 5. The hack, just let's windows XP think, it's Windows Server... Nothing fancy about it, just a small change. Since much of the source code is identical... I know real hardware raid is much better, but you can't get it cheaper than this. Most people don't have the money for real hardware raid like a 400mhz, 1Gb 3Ware card... But then again, most people use just standart Mainboards, wich do not go over the 133 or 150Mb/sec barrier of their board ( ATA S-ATA etc. ) To get the best out of that you need PCI-X 133 Mainboards, but that's to expensieve for most normal users. When using raid for speed get 2 fast hdd's like the raptors or Maxtor Plus series, raid0 and you will get your mainboard full at around 120mb/sec it won't go anny faster no matter how expensieve your hardware card is... I still use software raid on my new Mainboard, only now the S-ATA chips all have raid functions.... so i use them because the setup is so verry easy. ( onboard chips are also software raid...Promise, Via..all S-ATA/ATA chips aboard is Software raid ) But a cheap a** server for music, internet etc. HACK IT Thanks for the nice replies, ( post them in my guestbook hehe ) Take care for now.
