Currently i have a Samsung F1 750gb 32mb cache and a refurb Seagate 500gb 7200.11 32mb cache All the Seagate is used for is backup nothing else, i planned to use it for linux also but i never did. So all i wanted to know was the F3 worth the upgrade over the F1? I would be either going to sell both drives i currently have for a 1TB F3 or going to sell the Seagate, get a 500gb F3 and keep the F1 for backup. If its not worth the upgrade i wont bother. Its also particularly good for me to know how good the F3's are because i may need a drive for my mates build in January.
