Re: What's the point?

It could be double the IOPS *and* double the bandwidth, as long as there are two sets of electronics which can read/write to both halves simultaneously. People who don't need the IOPS could use it as a RAID0.
Having said that: I never understood why hard drives don't "stripe" across all heads. If you have 4K sector size (which is common in modern drives), and 8 heads, you could write a 512 byte chunk on each head simultaneously. You waste some capacity in inter-block gaps (which is what the 4K sector size was supposed to fix in the first place), but you get 8 times the throughput.
