Storage Review heeft een review gepost van Wester Digital WD307AA, een 5400rpm ATA66 harddisk met 2Mb cache. De grote platter-size van 10Gb maakt de schijf ondanks de lage rotatiesnelheid toch vrij snel:
Like the ill-fated WD205AA, the newest Caviar explores new frontiers in 5400rpm performance. Comparisons with the DiamondMax 40 yield favorable results. In Windows 95, for example, the WD leads the Maxtor by margins of 13% and 9% respectively in the Business and High-End Disk WinMarks. The Caviar maintains its edge, albeit slight, in Windows NT, an OS that's traditionally Maxtor territory. Here the Caviar slides by the DiamondMax by 6% in the Business WinMark and an unnoticeable 1% in High-End tests.ThreadMark results, however, place the WD307AA behind the DiamondMax 40. The WD trails the Maxtor by 18% under Windows 95. The gap narrows to 10% in NT.
