this is useful for archiving all your data, the cloud is dangerous for all your data picture/movies/musics , I have made my experience with mega upload 
good price for 1.25TB

No its not.. 26,49 euro for the disks plus 70 euro for the burner, so 96,49 euros for 1.25Tb.
A 3Tb drive is most cost efficient at 0.028ct per Gb, and for 3Tb worth of bluray youd pay 0.044ct per Gb.
So a harddrive is cheaper, plus they are reusable and much easier and faster to access.
Bluray disks also suffer from something called data rot, where disks go corrupt over time.
In almost every way, harddrives are a better choice.
