VAIO VPCZ11 SSD smart値晒し

1年半くらい使った VAIOZ VPCZ11 の SMART の値.SSDSAMSUNG MMCRE28G
swapあり(RAM 8GBだしほとんどスリープしかしないからあまりswap使わないけど),noatime つけたくらい.

tatsuru@moryo$ sudo smartctl -A /dev/sda                                                     [~]

Unused_Rsvd_Blk_Cnt_Tot が使われてって Used_Rsvd_Blk_Cnt_Tot に変わると字面から仮定して,この値が線形に増えていくとすると今の10倍,6万時間くらいは大丈夫そう
