Het vlaggeschip gaat 3 van deze platters herbergen (60Gb). Het is een 7200 Rpm uitvoering op ATA-100 met 2Mb Cache en een random searchtime van 8,5 miliseconden. Er zal ook een AS verschijnen met hydrolische (en zeer stille) lagers. Deze versie zal echter wel 5 tot 10% duurder zijn .":
The increased performance of the Fireball Plus AS is balanced with equally impressive acoustical improvements. Quantum's Quiet Drive Technology (QDT) paired with Hydrodynamic Bearing (HDB) motors creates one of the quietest 7200 RPM hard drives available. The Fireball Plus AS, utilizing HDB motors supplied by Quantum's manufacturing partner Matsushita-Kotobuki Electronics (MKE), generates less than 28 decibels of sound power at idle - quieter than a person whispering. In seek mode, the drive produces 32 decibels. Using standard ball bearing spindle motors and QDT, the Fireball Plus AS is one of the industry leaders in acoustical performance in the 7200 RPM class - generating less than 30 decibels of sound power at idle and 34 decibels in seek mode. [break]Over de hydrolische lagers:[/break] Hydrodynamic bearing motors utilize a combination of viscous oil and air rather than metal ball bearings, which contributes to a significant increase in hard drive reliability. HDB is an emerging technology that offers significant benefits in drive acoustics and shock and vibration performance. Because there is no metal-to-metal contact, the fatigue life of HDB motors is significantly extended.
