You also don't say how *big* your disks will be, and if your 5 bay NAS box can even split like that, and if it has the CPU to handle that. Is it an NFS connection to the rest of your systems?
Side note: NFSv4 really is much much better at this stuff than v3 ever was. With a fast enough network connection, I find NFSv4 as fast for more or less all workloads as NFSv3 was, mostly because of the lease support in v4 allowing client-side caching of the vast majority of files and directories that are either not written to or only written to by one client in a given short time window. (Obviously it also helps if your network is fast enough: 1GbE is going to be saturated many times over by a RAID array of any but the slowest modern HDDs. 10GbE and small 10GbE-capable switches are not very costly these days and is definitely worth investing in on the NFS server and any clients you care about.)
