PoliTech notes in a journal entry that "Vista is the gift that just keeps on giving." "Speaking during SanDisk's second-quarter earnings conference call, Chairman and [CEO] Eli Harari said that Windows Vista will present a special challenge for solid state drive makers. 'As soon as you get into Vista applications in notebook and desktop, you start running into very demanding applications because Vista is not optimized for flash memory solid state disk,' he said... 'The next generation controllers need to basically compensate for Vista shortfalls,' he said. 'Unfortunately, (SSDs) performance in the Vista environment falls short of what the market really needs and that is why we need to develop the next generation, which we'll start sampling end of this year, early next year.' Harari said this challenge alone is putting SanDisk behind schedule. "We have very good internal controller technology... That said, I'd say that we are now behind because we did not fully understand, frankly, the limitations in the Vista environment.'"
