    Over the past 2 months, I've resynced the blockchain on:

    • Intel Core Duo, 4GB RAM, 80GB 7200rpm drive - 2-3 days
    • Intel Core Duo, 4GB RAM, 60GB SSD - 3-4 hours
    • AMD A8, 6GB RAM, 120GB 7200rpm drive - 2-3 days
    • AMD A8, 6GB RAM, 60GB SSD 3-4 hours

    ...so I think the HD is the bottleneck. All were on Ubuntu 14.04 64-bit, and all of the rpm drives were older repurposed drives. Maybe a new rpm drive would be better but I haven't tried. Syncing is something any coin has to do at first and if the coin has been around, it will take some time no matter what. Once it's synced, RAM, HD, and CPU use are minimal.

    Thats a huge difference in time.  Is that just how slow those old hard drives were are all around or is there something unique about the way the blockchain is written?

    I'd theorize its a combination. If the blockchain can be written in parallel (which I think is true), then the whole process can take advantage of the fact that the daemon is pulling down data from multiple blocks simultaneously (which I think is true). A spinny HDD can't really do that much parallel....  (I think).

    You can't parallelize read/writes on an HD, due to the head physically moving to a location to read or write it. Trying to have parallel threads/processes reading/writing would have the opposite effect: HD don't like random access in general, and it would be a major slowdown.

    Monero's privacy and therefore fungibility are MUCH stronger than Bitcoin's. 
    This makes Monero a better candidate to deserve the term "digital cash".
