A New Breed of Hard Drive
Some hard drive companies design desktop-class drives with the Serial ATA (SATA) interface.
To meet the demands of enterprise storage, WD is going one better. Western Digital is the only
company combining an enterprise-class mechanical platform with the SATA interface to meet
all the demands of the enterprise environment – reliability, performance, and reduced cost.
