Fastes way to write to a file?

[matale]

I currently have something like this in my code

For intIndex = 1 To 1000
            objWriter.Write("a")
Next intIndex

Is there a faster way to write to a file? Especially for higher values of intIndex, doesnt matter if Im writing characters or whatever. Im just trying to fill a file full of data as fast as possible.

I know that for text and .DAT files you can use the StreamReader function which is much better
