  • Best Answer:

    No hard drive will last for 100 years. It is probably flash memory that you are seeing that quoted on, but that will come in much smaller capacities (typically 8GB-64GB) and a much higher cost-per-gigabyte than the Time Capsule, and of course, do not include a fairly high end wireless router.

    Hard drives have an average lifespan of approximately 5 years, but there are plenty of outliers, with some lasting 10 years and some only 10 minutes. And of course, the Time Capsule also contains a wireless router, which in itself will probably only last 3-5 years of continuous usage. That is why the recommendation for backups is always to have multiple backups, and preferably, to have at least one backup "offsite" (that is, not in the same physical location as your other backups), as the odds of multiple backups failing simultaneously is vanishingly small.
