Question about Seagate BarraCuda

According to the manufacturer's website, this drive runs at 5'400 RPM and not 7'200 RPM as written here, so who is right? There are mistakes very frequently on the digitech site, it's tiring in the long run, couldn't one check the info before writing it on a sales site, it would be the least they could do, rather than misleading the customer ... or is it just negligence?
