This is a technical part of an earlier post about setting up Storage Spaces on Windows 10.
There are dozens of RAID products on the market that allow users to combine multiple hard drives in various combinations and many tech-minded people choose these RAID configurations, thinking that hardware RAID is the best solution money can buy.
The reality is, however, that when these consumer-level RAID enclosures fail, their owners end up either losing their data or spending time and money on data recovery. The manufacturer usually just advises users to backup data when setting up a RAID configuration, which is not helpful for terabytes worth of data.
A software-based drive pool is not as fast and is not a plug-an-play solution as a typical hardware RAID configuration, but it is more resilient against enclosure failures because a failed enclosure just houses separate drives and in most cases can be replaced with another one, even from a different manufacturer, and the software drive pool will continue working as if nothing happened.
