Type in dmesg at the console, use scroll lock and the up/down keys to 
move around.

somewhere around the end of it it will display something such as "ad0: 
38154MB <TOSHIBA MK4025GAS> [77520/16/63] ata0-master BIOSPIO".

Common Drive speeds (in newer computers):
EIDE(ATA): 7200, 5400
SATA: 7200, 10000
SCSI: 10000, 15000
laptop: 4200, 5400
