Seagate's revolutionary X15, the world's first drive featuring a 15,000 RPM spindle speed, stood alone for all of 2000 as the only drive to deliver next-generation performance levels. The drive proved popular both with enterprise/IT purchasers as well as individuals who simply had to have the latest in bleeding-edge performance. This year, in addition to the X15's successor, we've witnessed announced competition from IBM and Fujitsu. Even so, Seagate's X15-36LP is the only drive shipping to channels. IBM's drive, though announced in February and reviewed by SR in June, hasn't been spotted yet. Fujitsu's announcement came in May, so hopefully the MAM drive reviewed here will hit the channel soon.
Fujitsu's MAM series goes head-to-head with the Cheetah X15-36LP, directly challenging the hegemony carved out by Seagate's newest dynasty. In addition to its 15,000 RPM spindle speed, the MAM3367 features a specified seek time of 3.5 milliseconds, the lowest yet for a 36 GB 15k RPM drive. It packs 9 gigs per platter, matching the areal density of Seagate's drive and exceeding Big Blue's by 50%. Fujitsu equips the MAM with 8 megabytes of buffer, again matching Seagate while doubling IBM.
Available in 18- and 36-gigabyte capacities, the MAM squarely targets the highest of high-end applications, areas where speed is of utmost importance. Though this review sample features an Ultra160 interface, the family will migrate to Ultra320 as the improved SCSI interface starts to permeate the industry. Fibre Channel versions of the drive are also available. An enterprise-class 5-year warranty protects the drive.
SR normally reviews the 68-pin UW/U2W/Ultra160 versions of SCSI drives. At the time of testing, however, Fujitsu could only offer us an 80-pin SCA unit. To expedite results, we accepted the SCA drive. An adapter converted the drive down to standard 68-pin data and 4-pin Molex power connections. The results presented below also represent the 68-pin LVD unit.
Let's turn to some figures and see how the MAM measures up!
