I'm currently very pleased with the SanDisk Extreme Plus micro SD cards. They are quite expensive, but behave way better with random writes. Event better in random write performance are the SanDisk Extreme USB sticks. Also quite expensive though and quite big. I can't tell, however, if they are better in case of power loss related data corruption. -- B.Walter <be...@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm. _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
