But as far as I can tell there are effectively only three drive manufacturers left - Seagate, WD and Toshiba. The SMR stunt was a real cock-up as far as raid was concerned - they moved their WD Red "ideal for raid and NAS" drives over to SMR and promptly started killing raid arrays left right and centre as people replaced drives ... you now need Red Pro so the advice for raid is just "Avoid WD". >From what I can make out with Seagate, the old Barracuda line is pretty much all CMR, they had just started making some of them SMR when the brown stuff hit the rotating blades. So now it seems pretty clear, they renamed the SMR drives BarraCuda (note the *slight* change), and they still make CMR drives as FireCuda. Toshiba "I know nuttin'". Cheers, Wol Cheers, Wol
