Si está de acuerdo con las utilidades de la línea de comandos, siempre puede usar smartmontools
desde http://www.smartmontools.org/ .
Necesitaría XCode para compilarlos desde la fuente (a menos que alguien aquí conozca la distribución binaria para Mac OSX), pero si recuerdo correctamente, no tuve problemas para compilar el paquete.
Tengo una SSD OCZ adaptada a mi MBP 15 "a mediados de 2010 y puedo usar el smartctl
comando para monitorear varias estadísticas, incluyendo sus Bytes totales escritos (llamados aquí Lifetime_Writes), así como el Indicador de desgaste de medios (mostrado como porcentaje).
Para darle una idea, aquí está el resultado de ejemplo:
MacBook:~😈 smartctl -a /dev/disk0
smartctl 6.0 2012-10-10 r3643 [x86_64-apple-darwin12.2.0] (local build)
