That article appears to push the view that all drives blessed with the magical TRIM wand are bug-free and well tested on all OS's, everywhere, and get free performance as a result, and bad ol' Apple is doing it disabling it as a punishment to people doing upgrades. They're missing the elephant in the room - on many drives, TRIM support is broken in ways that cause data loss. This is mainly with older drives (which are likely still in use), but does happen with more recent drives - see http://www.pcengines.ch/msata16a.htm as an example from the last year. Apple isn't being anticompetitive - they're being hyperconservative in terms of preventing data loss by not auto-enabling a feature that is known to cause data loss on poorly engineered hardware, and whitelisting the hardware they've tested and know works. The other security bits (kernel driver signing) are just welcome modern features that finally are coming to OS X, that have the side effect of disabling a dirty hack of doing binary patches to a disk driver. That all said, it would be nice if there was some way to flip on the TRIM switch without turning off driver signing, and allow knowledgeable users to live dangerously. - Zack -- Zack Williams - Artisan Computer Services - 520.867.8701 [email protected] http://www.artisancomputer.com ACSA, MCP SBS, SCSA, LPIC-1 _______________________________________________ Discuss mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
