The Escalade 7410 is somewhat of a mixed bag. Those who demand high sequential IO performance will appreciate the adapters's 64-bit PCI support. Although we weren't able to test the card in a 64-bit PCI slot, there's little doubt that it can deliver sequential transfer rates significantly higher than what a 32-bit/33MHz PCI bus allows.
When it comes to random IO performance, the Escalade 7410 currently brings very little performance improvement relative to Escalade 6400. In RAID 0, 1, and 01, this may not be too surprising. (Hindsight is always 20/20, no?) After all, it may not be unreasonable to take a "The Escalade 6400 performs so well that we can't fault the Escalade 7410 for not doing better" type of attitude for these RAID levels.
RAID 5, however, is another story. Although the 7410 features significantly higher RAID 5 sequential write performance relative to the 6400, its overall RAID 5 performance remains disappointing. We hoped for significantly improved scores - what we received, however, was a performance increase averaging only 2%. We are hopeful that these numbers can be improved sometime in the future by new firmware and/or drivers. If this turns out to be the case, we'll take another look at the 7410's performance at that time.
