Data storage company Adaptec has agreed to acquire Aristos Logic Corp for $41 million in cash, less than half the $91 million that Aristos has raised in venture backing since 2000, according to VentureWire.

The Foothill Ranch, Calif, company provides RAID (redundant array of independent disks) storage processing technology to optimize communication between servers and hard disks. its backers include Panorama Capital, Quicksilver Ventures, TPG Ventures (now TPG Growth) and Woodside Fund. It has been more than two years since a Woodside-backed company has made an exit.
