Currently I'm debating about whether I want to use a spare workstation running Windows 10 and turn that into the enclosure for a 4x6TB RAID 10 array since it has decent hardware specs or wait until there's room in the budget to purchase a dedicated NAS enclosure from Synology or some other vendor if what I want isn't possible as I would have to reformat/re-array for the enclosure. I know there is some difficulty with software <-> hardware driven array migrations according to this Q&A from '09:
Moving a RAID array from one machine to another
However given 7 years have passed and the rise of NAS storage for small business I was wondering if things have changed and if it's possible to have the RAID 10 initially set up in a spare workstation to use now and then migrate the RAID array and it's data w/o issue to a dedicated NAS enclosure from Synology et al when there's more money so that I can then free up the workstation again.
