Do I really need the hpt370 controller of abit kt7a? What does it do? What happens if I disable it?

That's it

 

[Riddler]

it enables the raid function of your motherboard- you don't need it if you aren't gonna run a raid array- you can disable it in your bios, and your computer will start up a little quicker because it won't look for the raid array while booting.

So if I disable it , my hd velocity will slow down or not. I'm not using raid. Do I have to change any cable or something else?

The advantages of the raid controller is, as Riddler said, the ability to add a raid hard drive configuration. Also it alows you to have 4 additional, no-raid hard drives. So if you get a dvd and a cdrw and a cdr and zip drive you still have 4 places to put a hard drive. Disabling the raid controller in the bios, if you aren't going to use it, will speed boot-up because the raid bios isn't initialized. If you do use the raid controller as a raid controller it will take a higher percentage of your cpu's time than if you ran it as an additional IDE controller.
Clear as mud?

Even if you don't plan on using RAID, as Pederv says, it has other advantages. Being able to slide 4 IDE devices in, with each on their own channel is a big deal. This lets each device run at its fastest speed without something else to slow it down.
