Looks like membership is limited to companies and costs US$1,700 a year. http://sata-io.org/ SCSI is from the T10 committee: http://www.t10.org/ The intro page indicates it's a fairly open group: # T10 operates under INCITS and is responsible for SCSI Storage # Interfaces. Its principal work is the Small Computer System # Interface (SCSI), including the family of SCSI-3 projects. # Anyone "directly and materially affected" is welcome to # participate on T10 (essentially, this amounts to anyone # interested in T10's work). cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC
