The MG09 is Toshiba's latest enterprise nearline line, the 18TB generation: 7200rpm, a 512MB cache, and a five-year warranty, per the Toshiba MG-Series data sheet. It uses flux-control MAMR (microwave-assisted magnetic recording) heads to reach capacities the prior generation could not fit on the same platter count, while staying CMR and SATA-compatible. For a buyer, the MG09 is the 18TB enterprise option when Exos X18 or Ultrastar pricing sags the other way.
