    See chart below for even options with more cores, focusing on slowest (thus cheaper) speeds.

    Also, see section below chart for why we are pricing two-processor server options instead of  single- or four-processor servers.

    $1,499 2.0TB SSD

    2TB is 4 times the space:

    2.0TB Samsung 960 PRO M.2 PCIe 3.0 x4 NVMe Solid State Drive (cost is $1,100)

    This is the fastest option since combines OS and data on fast bus. However, this may be the maximum TBs of storage doing it this way. (Can dig deeper, if necessary to decision-making.)

    If need more than 2TB total, must use more complicated multiple storage option. Example:

    OS only: 512GB Samsung 960 PRO M.2 PCIe 3.0 x4 NVMe Solid State Drive

    (cost is $399).

    AND choose a single main storage drive. For example:

    Data ONLY fast SSD:

    • 3.84TB => $1,500 - 2,000
    • 7.68TB => $3,000

    Data ONLY slow spinning, compared to current desktop:

    • 4TB => $200

    NOTE: Can also get a server with just ONE processor (at half the marginal cost), if core-count is sufficient.

    Why server with 2 processors? Why not one or four, for example?

    No savings buying just a one-processor server, especially if want more cores. JUST the price of the process jumps by the cost of an entire server!

    • +$5,080: 16 total cores => 24 total cores (one proc)

    Consider four processors only if needed and can afford many more cores. Option is not cost-effective for the core-counts we are currently looking at. Other considerations:

    • Currently, only older processors are currently as  an option with four-processor servers.
    • Server prices START at about $12,000, for 32 total cores.
    • Core counts and price upgrades are "times 4", not "times 2".
