Desktop External Hard Drive

Can this store games on and play them from the hard drive from a MacBook air ?

Asked by: Emma95
Technically yes, this could perform this function, but due to the read speeds of USB 3.0 being far lower than that of an internal drive, I would not recommend using for games.

I see WD do a version "for Mac", but you state that this is suitable for mac. Can you please confirm that this model will work perfectly as an external hard drive for my imac. thanks in advance

Asked by: Scriptwriterstuart
Yes this will work fine however this will need formatting on your iMac. The WD versions which are advertised as "for mac" are already pre-formatted and have been certified by Apple, but these will still work fine

Data transfer rate?

Asked by: joem0
The manufacturer of the drive utilises different models of drives inside the unit, meaning that the transfer rates are variable. To this end the specification is not stated by the manufacturer as no definite figures can be guaranteed.
