Does Legato Outpace NSI?: Page 4 of 5

RepliStor didn’t win at every level, however. The VeriTest study shows, for instance, that at 1000 and 100 Mbit/s, NSI’s software was 27.9 percent faster on the incremental synchronizations at 5 percent data change and 8.4 percent faster at 25 percent data change.

All in all, however, Legato came out of the study looking like a true Rocky in the ring -- the opponent beaten to a pulp.

No matter how accurate the test data may be, the huge performance difference seems a bit strange, especially in light of the patent infringement lawsuit Legato filed against NSI earlier this year (see Legato Lobs Lawsuit at NSI). The company has charged that the smaller vendor in fact swiped its RepliStor patents to create Double-Take.

“There are some other things we can do in the product that are different than the patented ideas that are in there,” Symons says to explain how two products supposedly based on the same patent show such deviating performance.

Legato also announced today that VeriTest has certified RepliStor for Windows 2000 and Windows Server 2003.
