Re: Collocated data

And what exactly is wrong with having what is effectively two independent drives? You get X IOPS per drive, so having two drives (whether two physical drives or two "effectively independent" drives) gives you 2X IOPS. Just because you don't have two heads able to access the same block of data isn't a bad thing. Servers always have a lot of outstanding requests, so they'll be able to get through the queue 2X as quickly as they could otherwise.

Remember, this isn't targeted at home users who will generally have little or no parallelism in their I/O requests. Those people are going to be using SSDs, not 20 TB HAMR drives.
