Conclusions
In summary, the Iwill WO2-R is an impressive board. It excels in its features and frills offered, delivering most of the goods as promised. In addition, it also boasts good stability and unpretentious userbility. The inclusions of various extras, like "giraffe-necked" jumper heads and well-thought out component placements truly speaks of the design efforts rendered to ensure its cut above the rest of the I815E pack.
On RAID functionality, it exhibits strong performance with its dual-channeled UATA-100 capability. However, akin to most ATA-100 RAID implementations today, the "wave" effect as seen in HDTach, indicates arbitration issues that would hopefully be fixed with driver revisions. Yet, this is not an issue with the WO2-R per se, but seems to be rather chipset related. The RAID_1/Mirrored offering also provides intelligent operations and promotes uninterrupted use.
The only qualms "nit-pickable" on the board, would be its weak memory performance (despite running at 133MHz) resulting from no interleaving support, which is inherited from the I815E's accompanying architecture.
I have no reservations recommending this board, especially with its abundant offerings and deliverables. It unassumingly receives our HW1 Editor's Choice award.
With rock stability (under Win2K), which I personally consider much more important over intermittent speed improvements, this board well deserves its recognition. However, Abit's latest SA6R release could offer a formidable challenge to its crownship. But that's another story....
