No question go for Harddrive. BUT don't put your trust on just one drive either. The power up and power down puts a lot of strain on the drive, you are just better to leave the drive on all the time. Better option would be a NAS with RAID setup. 

I have had a few drives gone belly up, lucky I had them setup as RAID and had a backup of the backup.

I don't trust CDs and DVDs for backup. I don't think I would trust Bluray either. I have had discs go bad on me over time. For that much data I would use an external hard drive.
