Verbatim is a middle-of-the-road storage device provider but they give us a screaming value here with the ToughMAX. It packs a lot of storage into a little key less than 2″ in length, with a removable rubberized cap. This cap helps it be waterproof, less temperature-sensitive, and crush-resistant.

The USBs We Compared

Our research narrowed the field down to several flash drive brands and models that we compared: Corsair, Verbatim, iStorage, Apricorn, Samsung, PNY, Kingston, SanDisk, Onn, and more.

You can see our full list of review criteria below in the What to Look For section, with an explanation for each.

We considered a wide range of USB storage across many different manufacturers.

We’re always looking for new and better gear, so if you have a USB drive that durably protects your documents, let us know in the comments. We review most of our tested gear annually so we can try to get it in the next roundup round and see if it will beat out our top picks.


What to Look For

The best USB flash drives have a few features to look for:

  1. Value
  2. Storage Capacity
  3. Security
  4. Durability
  5. Versatility

When you get the right blend of these, you can find the perfect storage for your prepping documents and survival guides. Below, we break down what each of these features means for the keys that truly set themselves apart.

Value: Cost vs. Benefit

The amount of money you spend on something like a USB drive shouldn’t blow out your entire budget. Most people have some spares in their junk drawer from over the years, so you could always find one for free if our suggestions are too costly.

You never want to spend too much money on one resource, even when it comes to document security. It’s better to diversify your spending to make sure you are covered for a wide range of scenarios.

Storage Capacity

What’s the point of a great storage device if it can’t hold very much? Capacity will dictate how many documents, guides, and Wikipedia downloads you can fit on your device so you’ll need to plan accordingly.

Copies of essential documents and plans don’t take up much room but using it for a complete survival library will. Just pick which one you’ll use it for:

  • Essential documents and plans: 4GB
  • Survival guides, maps, and specific knowledge: 32GB
  • Knowledge Vault (preserve and rebuild): 256GB, ex: a Wikipedia download is 22GB without media

As you can see, your intended survival solution has a big effect on what you’ll need for storage. You can also choose to use multiple USB drives if you need more capacity, want to organize files physically, or want redundancy.

Security

Most people don’t plan on misplacing or having others access their files, but not everything goes as planned. Both software encryption and physical locks work well to keep people from accessing your storage.

Many people end up misplacing their USB keys because they are small and lightweight. If you end up stashing one in a survival cache, make sure you keep a record of where it is.

Durability

Rugged rubberized polymer with aluminum frames set the standard for rough-and-tumble USB keys that may need to take a beating. Weather seals and port covers help some models take a ton of punishment without breaking.

Versatility

Some USB drives come with extra features, whether it’s security software or a lanyard hole for easy carrying. These versatile additions make a difference beyond the rest of our criteria since you can use the USB key in more situations.


What to Store on a Survival USB

People have been storing a wide range of information on USBs since they first showed up in 2000, but certain types of documents, programs, and files make sense for survival.

Here is what we recommend for storage:

  • Identification Documents – pictures of you and your family’s ID, passport, etc.
  • Emergency Plan – your emergency plan along with important contact numbers.
  • Prepping Checklists – checklists to parse through and keep organized.
  • Survival Guides – PDFs of important survival manuals.
  • Local Maps – free maps make it easy to know where you’re headed.

If you have storage left over, many preppers opt to include:

  • Personal Pictures – remember family, pets, and life moments but also document your belongings for insurance purposes.
  • Ebooks (for Entertainment) – there is a lot more downtime during emergencies than you may realize.
  • Wikipedia Download – great for knowledge preservation.
  • Non-Survival Manuals – firearms, farming, car repair, etc.
  • Disk Wipe eraser utility that is portable, free, and thorough. Wipe your electronic records if you are bugging out permanently.

Depending on what you store, looking into encryption software or going with our secure pick may be the best way to go. You don’t want anyone getting a hold of your personal info and bank account numbers.


Who Needs a Survival USB?

Nobody needs a USB drive for survival. But, the documents and information you put on it could be vital in a wide range of emergencies. We don’t consider USB drives essential, largely because you could carry hardcopies of documents and plans- or you could forgo them altogether if you need to.

I do keep USB drives in my survival kits and suggest them mainly for this kit:

They aren’t essential, but many preppers include them in additional kits:

If you find yourself with extras, they are useful around the house and I find myself needing them for random equipment and tasks while I’m on the go.

How We Review Products: We research thoroughly before selecting the best products to review. We have vast prepping and survival experience and bring in outside experts when needed. Hours on end are spent testing gear in stressful conditions and using specialized testing gear to verify claims. We assign performance criteria and impartially rate each tested item.

Sources and References

All of our experience and the testing we do to determine the best survival USB are useless without listing our research sources and references. We leaned on these for the book knowledge that we paired with our hands-on testing and practical survival experience:

The Final Word

Way back in 2000, when a little-known inventor from Singapore brought the first USB thumb drive to a trade show, most people didn’t realize how long that simple solution would stick around. It’s still one of the best ways to keep data and information mobile, and it applies to prepping plans, checklists, maps, survival guides, and more.

Here are a few other gear reviews and guides our subscribers have found helpful:

We presented quite a lot of information, but as always: if you have any questions let us know and we would be happy to help. Our testing found the Verbatim ToughMAX Flash Drive to be the best solution given its value, storage capacity, security, durability, and versatility.

Keep exploring, stay prepared, and be safe.
