Performance should be on par with a RAID 0 of comparable drives.
 


Agreed - for several years, I'd wondered why there hadn't been drives developed, particularly in multi-platter scenarios, with separate actuators, and maybe the possibility of built-in RAID-like functionality.

It might be a negative thing if you ever Defrag one of these hard drives since it might stick all the files on one area and the extra speed wouldn't be used.

If you stripe the data, you get a RAID 0 array all the time. What I want to know is why isn't this done in hardware at a drive level, invisible to the OS?
 
but now your next hard drive may be twice as fast as any drive on the market.
Maybe... If you buy the highest capacity drives and don't plan on buying one for a while. I get the impression that this is most likely to only appear in the highest capacity models, at least initially. The cost of adding these components to a drive priced in the sub-$100 range might be notable, but with the highest capacity 8-platter drives priced around $500, the cost of doubling up these components should make a relatively minimal difference to the total cost of such a drive.
 
Increasing the read/write speed is fine but can not compete with SSD on that front. Given the rising cost of SSD and memory as of late HD makers seem ok with throwing a golden opportunity. They just go along with extremely outdated decade+ capacity for $50 in 1TB. To make matters worse they also sale right at decade old capacitys at $75 with their 2TB. The 4TB drive capacity is turning 8 years old in 2018 and its anywhere from $120~200. Point is people already have them and forgo a small SSD with hard drive to pick up just a larger SSD. Last few years HD makers have fallen to point that SSD are of the capacity of their low end models. This is in part the reason memory/SSD prices are at all time high.

I would think a second set of heads on the opposite side of the drive would give you even more potential benefits. and also redundant access to the data if there is a problem with the first drive head set.
