The MAB3091SPís performance lagged behind that of similar priced drives, including IBMís Ultrastar 9ES and especially the Quantum Viking II. Compared to the Viking, the Fuji lagged 2-9% in ZDís WinMarks scores and 13-15% in Adaptecís ThreadMark.
Fujiís drive, simply stated, is the quietest SCSI drive Iíve tested to date. Thereís no high-pitch whine, and both idle and seek noise was below that of the impressively-silent IBM Ultrastar 9ES. Operating in a drive cooler, the drive ran very cool- it probably didnít need the extra ventilation.
The Fujitsu MAB3091SP (am I the only one who thinks Fuji needs to come up with a catchy name for their drive lines??) provides an option for those who must go with SCSI yet demand the utmost in silent operation. The drives performance, though not stellar, is still adequate. One probably wouldnít notice the gaps posted between the Viking II and the Fuji. I admit Iím still partial to the Quantum, but low operational-noise makes the MAB3091SP the right drive for some.
