Or stick with 1 NAS?
Second question.. Can I grow the storage with any of those devices? Like say I buy 1 drive to begin and then add a 2nd 3rd and 4th. will it auto add them to the raid pool? Or will i have to reformat and lose the data to do that? Its a pretty expenisve initial investment so I was just curious how I can grow the storage from day 1.
I posed basically this same question when I was deciding between the 1812+ and 2413+. With the 1512, I think you can go up to two expansion units - and these are physical expansions... so the SKU is slightly different so I'm unsure if there any limitations to them vs. multiple 1512s. For me, I didn't want a lot of different devices, so I just ponied up with the 2413+. Right now I have 5, 3TB drives with SHR2 (two disks can fail). Other folks I queried seemed to have wanted to have gone bigger at the beginning.
Between the two, I'd definately get the 1512+. I think you'll appreciate the extra expansion with the 1512+ and regret having just the 4 drives, IMO.
On your second question - yes, you can expand as you go, though it can take a while for the volume to rebuild (I think there's a tiny amount of risk of data loss during this period, but it's pretty moot IMO). Just understand that if you start with a 2TB drive and then add a 3TB, you can't expand again with a smaller drive (you'd need to use 3TB or bigger drives); if you don't, I think you end up missing out on space (or maybe it just denies you adding to the existing volume). You could always re-create the entire volume with all the drives, but you'd need to backup and move stuff back on it (of course).
