Reliability - It just stinks when you lose both a primary and failover secondary device for hardware problems at the same time (seems like we lose more hard drives these days than anything). For servers, you're talking a device that comes to the table offering bus speeds. Mostly zero latency and capable of line speed. Develop your solution based on network performance and this device gives you a shot of adrenaline in the performance run. I'd be awesome if they had a ddr2 and sata-2 version, hopefully it's in the works. Has anyone worked with these in a solution that makes this device the only storage device on a system? I'd be interested in hearing more about this subject as this gets rid of drive seek times. CLD
