[wellylug] Configuring HD

Hi all

Simple question : 
the IO_support below shows a 32 bit ON.
It has been suggested to me to turn it to 16 bit for better performances.

I am a "bit" confused about that. I thought that 32 bit would be faster.

Can anyone light this up for me please ? 

thanks a lot
Edouard 

[root at wairarapa root]# hdparm -v /dev/hda

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 5005/255/63, sectors = 80418240, start = 0
