Apple’s Fusion Feels Like A “Windows Software RAID”

Yes, it’s true that Apple new drive setup named Fusion is NOT a Software RAID – what I’m using is a metaphor, so bare with me on this. In fact, Mac Observer’s look at the technology get’s right to the point on RAID as well as what it does:

This is not a simple RAID, however, as 100% of the “magic” is done within OS X itself. What Fusion Drive does is it watches what files and applications you run most regularly and it moves them to the SSD. It will also take stuff that you aren’t using all that often and moves it to the mechanical drive.

What this is, however, looks very similar to other software-based solutions to memory/speed/access issues. The example I use is of Microsoft’s Software RAID capabilities in Windows. While it does work, we would rather trust that process to the speedier hardware RAID controller than take a perceived performance hit by doing it inside of Windows. Almost no network administrator I know would trust a RAID subsystem to Windows (over vastly superior hardware solutions).

There are no more results.
