For the last several decades, we have been using local hard disks or Network Attached Storage (NAS) drives to store our data. The photos we accumulated over the years, videos we created on special events (or YouTube), and documents we use on a daily basis are critical data we cannot lose. The advantages of using local drive over cloud storage are that it is fast (10X faster), cheaper (per megabyte), large capacity (1TB+), and available locally (portable and private). The disadvantages of using local hard drives are reliability (corruption and crash) and local (physical damage, fire, thunder). The average lifespan of physical hard drives is anywhere from 3 to 5 years, and they will need to be replaced for reliable backup. To circumvent reliability issues, one may choose to use NAS drive with RAID 1 mirroring instead. Video content creators such as YouTubers may want to use NAS drive along with cloud storage to utilize the best of both worlds.
