OS X Server brings even extra power to your organization, home office, or college. I have a old system that runs Stablebit Drivepool (Storage Spaces was just a tiny too fundamental at the time that I put the system with each other, and still is), and it has like eight plain old drives in it, no RAID at all, just one massive pool.
A lot of network-attached storage appliances on the industry are prepared and in a position to tackle your storage wants, but acquiring one can be an high-priced alternative-particularly if you have only a handful of files that you want to share with a couple of machines.
Even though you can develop storage spaces of practically any size, every time you generate a new virtual drive, you will be employing a small portion of the physically readily available storage, and ultimately, you will run out of space as you hold creating far more storage spaces.
I have been employing Synology DiskStation two-Bay Network Attached Storage for years ( newest model is DS215j ), but if you think your media library will grow considerably in the future, I would suggest you start off with a 4-bay model such as Synology DS414j so you can develop into it even if you only commence off with two drives.
With the drive attached as a network volume, your computer system can act as the conduit even if it is got practically nothing stored locally, serving media through a regional UPnP server (like Tversity for Windows or MediaLink for OS X) and giving remote access to a neighborhood drive.
