You did notice the " " around the words hard drive, did you not?
No, it isn't a true HDD - but it better & easier to work with than the previous way one used SD cards in the Wii.
Plus, it does needed "fridge cleaning" for you or at the least severely streamlines it. If your SDHC-stored WiiWare game, for example, needs more internal memory to run than you currently have, 4.0 adds a new data management menu that will provide you with a menu of save data choices for you to select, then temporarily delete the data of choice to allow for enough space for the game you wish to play.
When this pops up, Wii will ask you to choose which data you want to temporarily move from internal, based on either block count, name or simply the rightmost location on the list of data "channels".
You still have to move regular, non online game save data from SD to internal if you need that stuff. But WiiWare/VC - which this solution is primarily here to address - just got easier to deal with/manage, esp if you buy a lot of it.
