Through a product announcement over eight months ago, Maxtor split its ATA line into a standard (DiamondMax) and a premium (MaXLine) offering. What advantages does MaXLine deliver over DiamondMaxes? Join StorageReview as we take a look at the 250-gigabyte MaXLine Plus II.
|
More than eight months have passed since Maxtor’s initial announcement. While it was originally supposed to top out at just 160 gigabytes, the DiamondMax Plus 9 has since hit 200 and even 250 gigabyte capacities. The MaXLine Plus II initially was to pick up the 200 and 250 GB points but has since been reduced to only the 250 GB size. At the time of this writing, MaXLine Plus II drives are finally trickling into the mainstream distribution channel.
There are actually two MaXLine series- the standard MaXLine features 5400 RPM operation while the MaXLine Plus incorporates 7200 RPM operation. The MaXLine Plus II features three 83-gigabyte platters along with the 7200 RPM spindle speed. Maxtor specifies average read seek times at 9.0 milliseconds. Though announced at the outset with both ball bearing and fluid bearing models, in practice (like the DiamondMax Plus 9), all MaxLine Plus drives feature quieter fluid dynamic bearing motors. The family comes equipped with a performance-standard 8-megabyte buffer.
What differentiates the MaXLine Plus II from a 250-gigabyte DiamondMax Plus 9? Though the firm has carefully maintained that the DiamondMax Plus 9 has been built to standards just as high as its predecessors, Maxtor claims that the MaXLine series goes above and beyond the ATA norm. It features a 1.2 million hour mean time between failure (MTBF) figure, matching the spec sported by the top SCSI drives. For those about to protest that they do not believe a drive will “run 137 years continuously” before failing, remember that MTBF is the total cumulative amount of hours a large group (500 to 1000) of the given drive should run before one of them fails. Maxtor rates the MaXLine for “24/7” operation. Many readers may remember the flack that IBM took for specifying the Deskstar 60GXP series with a “333 power-on hours per month” recommendation. Does the MaXLine’s 24/7 claim imply that other drives such as the DiamondMax Plus 9 or even the Deskstar 60GXP should not be powered on continuously? The issue remains somewhat fuzzy.
Finally, the MaXLine Plus II explicitly features a three-year warranty. In announcing the DiamondMax Plus 9, Maxtor fired the first salvo in reducing standard drive warranty lengths from three years down to just one year. To reflect its increased reliability, however, the MaXLine was to be protected by the previous three-year standard (though, interestingly, not by the SCSI-standard 5-year period). Like many issues surrounding Maxtor’s latest drives, however, the distinction is somewhat blurry. While all MaXLine drives are backed for three years, there have been many reports of readers receiving DiamondMax Plus 9 drives that, either in the packaging or through information provided on Maxtor’s website, appear to feature a three-year rather than the expected one-year warranty.
Why “II”? What happened to the MaXLine I? According to Maxtor, the 120 GB and 160 GB DiamondMax D540X drives were actually built to an elevated standard and hence, retroactively, are the first-generation MaXLine drives.
With the MaXLine, Maxtor aims to carve out a segment previously serviced by high-capacity, expensive SCSI hard disks and tape drives. Such secondary storage has traditionally been used to store or backup enormous amounts of data that users do not need to access as regularly as “first line” data. A reliable, high-capacity ATA drive ostensibly offers speed and cost advantages over traditional solutions. The MaxLine Plus II, of course, also serves as Maxtor’s premiere ATA offering to compete with drives from other manufacturers for use in mid- to high-end desktop systems as well as entry-level servers.
Low-Level ResultsFor diagnostic purposes only, StorageReview measures the following low-level parameters: Average Read Access Time– An average of 25,000 random accesses of a single sector each conducted through IPEAK SPT’s AnalyzeDisk suite. The high sample size permits a much more accurate reading than most typical benchmarks deliver and provides an excellent figure with which one may contrast the claimed access time (claimed seek time + the drive spindle speed’s average rotational latency) provided by manufacturers. WB99 Disk/Read Transfer Rate – Begin– The sequential transfer rate attained by the outermost zones in the hard disk. The figure typically represents the highest sustained transfer rate a drive delivers. WB99 Disk/Read Transfer Rate – End– The sequential transfer rate attained by the innermost zones in the hard disk. The figure typically represents the lowest sustained transfer rate a drive delivers. |

The MaXLine Plus II posts an average read access time of 13.7 milliseconds, right in line with the score of the DiamondMax Plus 9. Subtracting 4.2 ms to account for the latency incurred by a 7200 RPM spindle yields a measured average random seek time of 9.5 milliseconds- half a millisecond off of Maxtor’s claim.

Thanks to its high areal density, the MaXLine manages to deliver a 60 MB/sec transfer rate off of its outer zone. Inner-zone scores decay to a respectable 34.7 MB/sec.
Single-User PerformanceStorageReview uses the following tests to assess non-server use: StorageReview.com Office DriveMark 2002– A capture of 30 minutes of actual computer productivity use that exactingly recreates a typical office-style multitasking environment.

Partly due to its large capacity, the MaXLine Plus II is the first of Maxtor’s ATA drives to heave itself across the 400 I/O sec SR Office DriveMark barrier, placing itself in contention with drives from Western Digital and IBM.
Maxtor’s drive fares similarly in the High-End DriveMark with a 400 I/Os per second performance. The MaXLine turns in 373 I/Os per second in the Bootup DriveMark, a capture of Windows XP’s relatively high-queue-depth startup sequence. Both scores place the Maxtor second only to WD’s Caviar WD2500JB.
Finally, in the Gaming DriveMark, a normalized average of the performance delivered in 5 popular PC games, the MaXLine scores 527 I/Os per second, trailing the Deskstar 180GXP as well as the Caviar.

The MaXLine Plus II turns in scores similar to that of the DiamondMax Plus 9 in the SR Server DriveMarks. Even Seagate’s modest Barracuda ATA V manages to deliver better multi-user numbers. This is particularly unfortunate in light of the MaXLine’s explicitly stated MTBF, warranty, and power-on hours advantages over other “standard” ATA drives, attributes that otherwise make the drive particularly suitable for multi-user applications.
Legacy PerformanceeTesting Lab’s WinBench 99 Disk WinMark tests are benchmarks that attempt to measure desktop performance through a rather dated recording of high-level applications. Despite their age, the Disk WinMarks are somewhat of an industry standard. The following results serve only as a reference; SR does not factor them into final judgments and recommends that readers do the same. |

Heat and NoiseIdle Noise– The sound pressure emitted from a drive measured at a distance of 18 millimeters. The close-field measurement allows for increased resolution between drive sound pressures and eliminates interactions from outside environmental noise. Note that while the measurement is an A-weighted decibel score that weighs frequencies in proportion to human ear sensitivity, a low score does not necessarily predict whether or not a drive will exhibit a high-pitch whine that some may find intrusive. Conversely, a high score does not necessarily indicate that the drive exhibits an intrusive noise envelope. Net Drive Temperature– The highest temperature recorded from a 16-point sample of a drive’s top plate after it has been under heavy load for 80 minutes. The figures provided are net temperatures representing the difference between the measured drive temperature and ambient temperature. For more information, please click here. |

Equipped with Maxtor’s maturing fluid dynamic bearing motors, the MaXLine Plus II delivers an idle noise floor of just 41.8 dB/A despite its relatively high (three) platter count. Like recent Seagate Barracudas and IBM’s Deskstar 180GXP, one would be hard pressed to hear the MaXLine spinning away over even the quietest of power supply and CPU fans. Likewise, seeks remain fairly muffled.
After 80 minutes of intense operation, the MaXLine’s top-plate temperature hit 20.1 degrees Celsius above ambient temperature- at the high-end of the ATA spectrum. Still, it should be easy to integrate into any system that features proper ventilation.

ConclusionMaxtor’s MaXLine Plus II offers decent, though not category-leading, performance. The drive’s low idle noise makes it a significant alternative to the Western Digital Caviar WD2500JB for those seeking a high-performance, high-capacity drive in a quiet computing environment. $400 is a hefty price for an ATA drive, however, and the MaXLine’s spotty distribution means that it cannot indulge in the same regular discounting and rebates that the WD2500JB enjoys. The MaXLine’s main draw, however, is its presumably superior dependability. Assessing reliability within the confines of a review is, unfortunately, beyond the abilities of even the largest, well-funded operations. Keep an eye on the SR Drive Reliability Survey for an assessment of the MaXLine Plus II’s score. Time will tell whether or not Maxtor has raised the bar on this one. |
