Slow write on 3TB Green WD30EZRSDTL

Fixed!  :smiley:

My mistake; even though my Windows 7 system recognizes the 3TB drive, the HBA is required to give normal performance:

Interesting, I would like to know if the same thing happens with Motherboards that natively support 3TB drives without the need of the controller card…

Anyway, useful info!! Kudos for that!
