The 'UDMA' numbers are meaningless for _native_ SATA controllers/drives. They may be not meaningless for legacy SATA devices, using SATA->PATA bridge inside. Some bridges do not support UDMA133 on PATA part, so ata(4) prefers not to use it. But in this case it is indeed meaningless. -- Alexander Motin
