Het volk achter Tech-Review heeft een review gebakken rondom de Promise Ultra ATA/66 Controller. Na de installatie bleek de Maxtor 7200rpm schijf aardig wat sneller te zijn geworden:
Taking a look at the scores reveals the ATA 66 adapter scores are well above the non ATA 66 performance scores. Using Winbench 99 under Windows 98 SE reveals a 17% increase under Business Disk mark from ATA 33 to ATA 66. Benchmarking under the High End Disk mark reveals a whopping 49% performance increase. In the beginning of this year, this amount of performance gain did not occur with the ATA-66 adapters due to hard drive specifications. However, now that ATA-66 hard drives spinning at 7200 RPM have arrived, the true performance increase provided by ATA-66 adapters can be clearly seen.
While this may lead one to believe the increase from 33 MB/sec to 66 MB/sec bandwidth is the cause, this is truly not the case. The reason for the 66 MB/sec data transfer rate not being the performance enhancer is simply stated by the fact that current ATA hard drives cannot physically serve a constant 66 MB/sec stream. As of now, they cannot even constantly fill the 33 MB/sec of bandwidth provided by ATA 33. So why is there a performance increase if the increased bandwidth doesn't even come into action? The answer is in the fact that the Ultra66 takes the stress off of the motherboard to manage the hard drives and puts the load onto the separate PCI Ultra66. This simple fact combined with the more efficient ATA-66 specification results in the increase of performance for hard drives.
