Benchmark Kimsufi 16G 2012 OVH

Écrit le 13 06 2013 par Kévin MET _

Je continue ma série de benchmark avec cette fois une machine plus modeste. Il s'agit d'une Kimsufi 16G de 2012. Un bon modèle car il a de meilleurs performances qu'un SP 16 et coute 10€ de moins par mois. Le problème, c'est que cette offre n'est plus commercialisée et que la gamme 2013 est vraiment moins bonne. Le seule point positif avec la gamme 2013 c'est le RAID 1 soft.
