Has Phoronix has ever experimented with a Gigabyte I-RAM? Searched the site but didn't see anything. Would be an interesting read.
You have to initialize it with a Windows program. Maybe that could run in Wine or such. Then I'm guessing it would just look like a regular SATA drive.
I looked at some of the disk benchmarks with PTS but I didn't see options for testing a particular drive or partition.
With RAM prices coming down, maybe SSD will find itself competing with RW optical media.
