Another wrinkle is that these are almost certainly 4Ke blocks. So your mobo ports may not be able to understand/do anything with them.

You're probably better off buying a NAS enclosure - like the Drobo, Synology, QNap et al - and just letting it take care of the details.

The modern ones will almost certainly let you plug these drives straight in (but check, because I didn't). And you can use certain enclosure models as a DAS too, for faster access speeds (still slower than an HBA and internally-fitted drives, but quicker than 1GB network).

At least some of those enclosures offer features like transparently growing the array when you add more drives. Or swapping larger capacity drives in later to grow the array. Did I mention that there's no substitute for good backups?

They all offer different features (personal cloud, direct media playback through HDMI, plex etc etc). Pick the features that seem useful to you...
