Can anyone explain what the relationship betwean a TDAT and a physical drive is? My understanding is that a physical drive allocated to a thin pool is split into several Tdats.

also how is the raid spread amongst same drive types in a pool? If I have allocated the recommended 8 drives to a existing 6+2 RG in a thin pool do these drives stay as their own small group of 8 drives I.e less of a spindle spread.

TIA
