I bought the promise card because it acts like an abstraction layer between OS and RAID Array. Windows sees it as a huge 60GB drive, while it is really 2 30GBs. DOS sees it as one big disk.
I would like to point out that the FastTrak outperforms software raid in Windows. Take the same disk drives, same array configs and switch out between Promise and NT Software and you will see an increase (noticeable) when you use the FastTrak.
I know you are going to say "Who gives a crap about NT software RAID, this is a linux software raid list"....but I will remind you that I posted originally asking about what the best controller to buy for Linux RAID was.....I just mentioned as an aside I had a promise FastTrak on my windows box.
When the fasttrak does work on linux, I would like to see it compared against linux software raid.....
Also, isn't RAID5 incredibly slow on anything but a well cached hardware controller??? If yes, then why not use the FastTrak again?
Thanks,

i will point this out AGAIN. the promise fastTrak is NOT hardware raid. did
you really think 30 seconds with a soldering iron and a 7 cent resistor could
make a hardware raid device from a 20 dollar ide card?
there is no cpu on board the card, and all the 'raid' functionality is
provided in software, by the system cpu. think of it as 'WinRaid'.
you would be MUCH better off using software raid under linux where you can get
more modes (like raid5), or forking over some real currency to pick up a
hardware controller.
