Exactly. To expand: we are in the same pickle as the rest of the industry. This article gives some good background reading to David's words http://lwn.net/Articles/353411/ -- and if you've been following her writing, Valerie knows a ton about FSs, including work on ZFS. All we can do is - Tune our partitioning to match eraseblock boundaries to extend the life of the device by avoiding pointless churn. - Test the SDs hard hard HARD so we know that the FTL is not falling off a cliff in reliability or performance. Wad's torture-that-SD rig works on that angle. - Side with other Linux devs in asking for direct access, proper TRIM support, etc. Pray it happens :-) cheers, m -- [email protected] [email protected] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
