Cloud storage vs an external hard drive: which one should you trust?
Neither one is perfect. Here's when each actually makes sense, the failure modes of both, and the 3-2-1 backup rule that works for every family.
This is the question we get every week, and the honest answer is both. An external hard drive and a cloud service fail in completely different ways, which means together they cover each other's blind spots.
How hard drives actually fail
Spinning hard drives have a known mean time between failures measured in years. The failure mode is usually sudden and complete — one day it clicks, the next day it's gone. SSDs last longer on average but fail without warning too.
The subtler failure mode is the drive is fine, but your house isn't. A flood, a fire, a theft, or a kid spilling orange juice on it all count.
How cloud services fail
Cloud services rarely lose data. They fail in different ways: account lockouts, price hikes, company acquisitions, and the occasional we've decided to discontinue this product email. If you ever built a life on Google Jamboard, you know.
The 3-2-1 rule
The simplest backup strategy that actually works:
- 3 copies of anything important
- 2 different kinds of storage
- 1 copy off-site
For a normal family, that looks like: the original on your phone, a backup on an external drive at home, and a backup in the cloud. If any one of them fails, you still have the other two.
Enzonic Drive is designed to be the off-site copy. 24 GB free, no tracking, no ads, and a Pro tier at $2/month for 100 GB if you need more. It won't replace a home backup drive — but it will save you the day your backup drive dies.
