I currently have approximately 12TB of data stored across three 5TB Seagate One Touch external hard drives. I don't anticipate exceeding 15TB, so these three drives will likely be the permanent storage set I want to preserve long-term.
I also have three additional 5TB Seagate drives that serve as 1:1 cloned cold backups of the originals.
I'm sure some people will suggest a better storage solution, such as larger-capacity drives or a NAS. However, I already own these six drives, and unless there's a reasonably cost-effective alternative, I'd prefer to work with what I have rather than spend a lot of money upgrading everything.
I recently did a rough audit of my media collection and estimate that approximately 7.5TB (roughly half) consists of content that would be extremely difficult, if not impossible, to replace or download again.
With storage prices seemingly continuing to rise, I'm trying to figure out the most cost-effective way to ensure that my data, particularly that irreplaceable 7.5TB, survives for the long haul.
I've been doing some research online and through this subreddit. From what I've gathered, HDDs have an average useful lifespan that is often quoted at around 5–10 years, although I understand that any drive can fail at any time.
I'm trying to determine the best long-term preservation strategy. A few possibilities I've considered:
- Keep my current setup: Maintain the three primary drives and their three cloned backups, periodically checking drive health and replacing the primary or backup drives as needed.
- Create additional backups of essential data: Instead of maintaining 1:1 clones of all three drives, make an additional copy of the approximately 7.5TB of irreplaceable content. This would give that data three copies rather than two, while keeping the more easily replaceable media in a single copy with no backup..
- Consider another approach: Perhaps there's a more reliable or cost-effective way to manage long-term storage using the drives I already own.
I'm not particularly wealthy, so while I'm willing to invest in additional drives when necessary, I'd rather avoid spending a small fortune on a completely new storage setup.
What would you recommend for someone in my situation?
Would you stick with the existing six-drive arrangement, prioritize additional copies of the irreplaceable data, or take a different approach altogether?
EDIT: Thanks everyone for the suggestions and advice. I appreciate the different options suggested that I hadn't considered.
I'm trying to balance preserving my collection with the cost, complexity, and learning curve of unfamiliar technologies. I want a solution that's effective but also practical for me to maintain.
I'm currently leaning toward:
Creating an additional backup of my roughly 7.5TB of difficult-to-replace media and storing it off-site (I have easy access to a family member's location).
Using checksum verification to periodically check for silent data corruption.
One clarification: by "irreplaceable," I mean from an entertainment media perspective, not personal or family files. Losing it would be pretty disappointing, but not devastating. I'm simply trying to find a sensible balance between preservation and practicality.
Thanks again.
