      So Red would be just barely cheaper, RE would be just barely larger. Red would be faster for random writes. RE way faster for reads.

        If you went for smaller WD RE drives (2TB instead of 3TB) you could get 20TB usable for just $1,380.

          For everyone's reference:

          WD Red is consumer, 5400 RPM
          WD Red Pro is consumer, 7200 RPM
          WD RE is enterprise, 7200 RPM

            The trouble is at 24TB for backup there isn't much room for growth with this backup solution

            So larger drives would be needed.

              Then going to 30TB would be good.

                If you splurge to $2,352 you can leap to the 4TB RE drives and suddenly you have 40TB to work with!

                  Now that remains SATA. If you are worried about performance the 4TB WD RE SAS drives will give you a huge boost in random access and only cost $2,436. Now that much more.

                    And, of course, to overwhelm you with options, you could get WD RE 6TB drives and get 8 of them. This would be much slower and give you 36TB today in RAID 6. But over time you could grow up to 60TB in that setup. Up front 36TB cost would be $3,280.

                      So 3TB Drives RAID 6.

                      No write performance though from the RAID.

                      Off Hypervisor, over the internet at 5841GB (30MBps pipe Asymetric) ...
                      Weekly.... would take 21 Days to perform a single backup operation... (roughly)

                        I'm thinking our internet performance would have to take a huge leap as well for off site.

                          At those speeds you don't care about the write penalties of the RAID 6, you just need enough performance to take the WAN pipe speeds, which is almost nothing.

                            At least for weekly full backups. But if we only backup the primary drive (once a month)

                            We would reduce our storage needs, as well as bandwidth needs.

                              I assume you mean 30Mb/s. 30MB/s is 240Mb/s!! That would be pretty awesome.

                              If asymmetric, what is the full speed up and down?

                                30 Up and down.

                                Each way, is that not asymmetric?

                                  Mb/s sorry yeah not 30MB/s

                                  😛

                                    That's symmetric.

                                      Symmetric means "same in all directions."

                                      Asymmetric literally just means "not symmetric."

                                        Sorry.

                                        Either way it would still take ~ 22 days to perform an off-site full.

                                          Correct usage....

                                          Check that girl out, she is hot, her face is so symmetric!

                                          versus

                                          Dude, that girl is all wonky, her face is totally asymmetric!

                                            Which obviously isn't reasonable 😛
