Too much money, not enough innovation
I've a similar NDAS box. Where this one cost 54 Pounds Sterling, mine cost 59 US dollars - which I'm given to understand is quite a bit less dosh.
No drivers are needed with the one I have (I won't mention the brand name because I don't want to come off as a shill), and while it does support a direct USB connection, that's not why I bought it. It's meant to be attached to the network, and it's being used pretty constantly by two humans and a half-dozen unattended servers, with simultaneous read and write operations.
Frankly, anyone who can't figure out how to hook up a network cable and then query the DHCP server to find out the device's IP address (or do a MAC address lookup) has no business trying to operate a network. If you didn't know how to use that funny guage with the "kph" markings on it in a car, you shouldn't be driving, either. These are very basic parts of operating a network.
Requiring proprietary drivers, as Akasa does, is in my opinion merely a Microsoft-like attempt to lock the user into continuing with the same brand in future; it's meant to discourage buying more versatile, less expensive (and probably more reliable) products from other makers.
