Hello, Hope you are fine and safe. Hard drive configuration must be selected at the time of purchase and an upgrade is not an option. If you now have 3.5" drive chassis, you can use 2.5" on drives because there is a carrier to accommodate them. Might be a kind of hard drive bracket or convertor works.  But I have to say I don't have a try it so I'm not sure of this. If anyone in community has such an experience and shares it with us on this thread this will be helpful. page 135 [URL]    [IMAGE] Hope this will helps!
