Buffer size may be either 2 or 8 megabytes. In addition to platter densities, the drives come equipped with either ball bearing or the newer and quieter fluid dynamic bearing motors. The family as a whole incorporates a bewildering amount of options. Maxtor specifies an average read seek times of 9.4 milliseconds. The DM+9, just as all other DiamondMax Pluses, incorporates a 7200 RPM spindle speed. Though various members of the family feature differing platter densities and hence differing transfer rates and access times, Maxtor claims that all three densities will yield similar performance.
As a result, Maxtor pushed the Plus 9 to market incorporating 60- and 68- in addition to the 80-gigabyte per platter disks. The platters, and perhaps more importantly the supporting parts necessary to extract data so closely packed together, have been experiencing unusually low yields. In perhaps the surest sign yet that formerly inexorable increases in areal density are slowing, Maxtor quietly backed away from the 80 GB spec. Interestingly, however, there were indications that these drives in fact did not incorporate 80/GB platters as Maxtor initially indicated. Surely enough, DM+9s trickled into the channel about a month later. When they originally announced the DiamondMax Plus 9 (along with the Plus 8, DiamondMax 16, and Fireball 3) back in September, Maxtor trumpeted the fact that it would be the first firm to deploy 80-gigabyte platters across its entire ATA drive line.

Though we can’t tell you how to get the density of your choice, we can report the difference, if any, in performance. Our long-delayed Maxtor DiamondMax Plus 9 review has finally arrived! Confusingly enough, Maxtor ships these drives featuring three different platter sizes.
