Huh? You are comparing a 1999 disk drive (MAN3184M, 18Gb) to a 
2005/2006-circa SATA disk drive (Seagate Barracuda 7200.10)? It's like 
comparing oranges to apples IMHO. Get a 2006-circa SCSI disk drive and try 
again, perhaps..?

As a side note, my 300GB 10k7 SCSI Seagate looks about 40% faster than my 
ST3750640A (Barracuda 7200.10) disk drive using hdparm -t on two Dell 
workstations..
