It is still point of discussion. I have arguments for 3 different options:
  da - PRO: habitual CAM/SCSI disk name; CONTRA: ATA disk uses 
completely separate ATA-native peripheral driver, it is difficult use 
the same name for two drivers and it IMHO looks ugly:
  ad - PRO: habitual ATA disk name; CONTRA: heavily conflicts with 
ATA_STATIC_ID ata(4) option device unit numbering, also the same driver 
name conflict, but a bit easier due to different parent bus;
  ada - PRO: perfect from internal infrastructure PoV; CONTRA: just 
unhabitual.
