Since drives now consist of more than one disc (platter), why not treat them as separate drives?
Reliability. Redundancy. Read/Write Speed. etc.
From a consumer standpoint, I have little interest in buying a single HDD that's seen by the PC as 4 smaller HDD's. If a consumer wants a smaller HDD, they would just buy the smaller HDD or partition the larger one. No need to add complexity to already complex configurations.
It seems to me that what they're essentially doing is putting more drives into one box, under one controller; and that such large capacity require controller solutions. Hence my question.
he answered how I would, perhaps you could rephrase the question?
Hmm... Yeah, he'll need to rephrase the question.
As near as I can tell, the poster seems to be confusing or mashing the different aspects of a HDD.
The controller card mentioned is offered because a majority of the hardware & OS out there is still limited to ~2TB HDD. Until something like the GPT becomes standard hardware fare and everyone installs 64bit OSes, we'll see a lot of this. This exact sort of thing occurred when drives broke the ~137GB barrier. You either had to partition the drive to less than that or install some stupid crazy driver to get that support until more people moved up to the 32bit OSes.
There are actually a multitude of potential controllers between where the data is stored on the platter all the way to the CPU itself. Besides the card (which not everyone will require anyways), you *must* have a controller on the HDD. HDD's are wicked complex internally. Despite the fun we all had in the 90's ---smurfing--- up our computers with badly coded John Conway's Life simulators, it's probably better to leave the heavy lifting of managing the platters to the HDD controller itself. In other words, even if the HDD just had one platter, it'll still need a controller for management.
Platter != Drive. Stop thinking like that. A platter is just one component of a much larger whole. If we stayed with that logic, we'd be going gaga over 750GB drives. We did that four years ago.
