5 Best HomeBase & SSD Options for eufy S340 (2026)

Written by Ethan Walker

The eufy SoloCam S340 already gives you local recording, but once you start saving more motion events, adding another camera, or simply wanting a longer recording history, one question quickly appears: where should all that footage go?

That is where choosing the right HomeBase, HDD, or SSD for the eufy S340 becomes important. And it is also where buyers can easily spend money on the wrong thing. You may see 1TB, 2TB, SSD, HDD, HomeBase 3 and different bundles on Amazon without knowing which upgrade actually makes sense for your setup.

So the real decision is not simply “Which hard drive should I buy?” You first need to decide whether adding a HomeBase makes sense for your system, then choose between an SSD for a quiet, solid-state setup or an HDD when larger capacity for the money matters more.

Local recording can also be useful when you want your security setup to depend less on an always-active wireless connection. Our guide to security cameras without constant Wi-Fi explores other camera setups for homeowners who want recording options that are not built entirely around continuous Wi-Fi access.

Getting that choice right now can save you from buying storage twice. A drive that looks inexpensive may not be the best long-term choice if you plan to add more eufy cameras later, while an expensive high-capacity SSD can be unnecessary if your S340 only records occasional motion events.

Think about what happens after installation. Your S340 can capture visitors, deliveries, vehicles, pets and unexpected activity every day. If something important happens, the recording you need may not be from this morning; it could be footage from days or weeks earlier. More useful local storage gives you more room to keep that history instead of constantly thinking about capacity.

But bigger is not automatically better. The smartest purchase is the one that matches the number of cameras you have, how frequently they record, how long you want to retain footage, your budget, and whether you expect your eufy security system to grow.

That is why we narrowed the choices down to 5 practical HomeBase, HDD and SSD options for eufy S340 owners. We will compare which option is best overall, which makes sense for tighter budgets, which gives you more storage capacity, and which setup is worth paying extra for.

5 Best HomeBase & SSD Options for eufy S340 Compared

The best upgrade depends on what you are actually trying to add to your eufy SoloCam S340. A HomeBase expands the system itself, while an SSD expands storage inside a compatible HomeBase. That means these products should not be judged by price or capacity alone.

If the cabling work is the main reason you are hesitating on a full PoE setup, compare the eufy SoloCam E42 vs S340 to see how two standalone eufy cameras approach outdoor coverage when easier placement matters more than having every camera connected to a central NVR.

For most S340 owners, HomeBase 3 is the most practical place to start. It creates the expandable-storage path and lets you choose a compatible 2.5-inch SATA drive later. The HomeBase Professional S1 is the more ambitious hub for buyers who value features such as backup power and 4G connectivity, while the Crucial and Samsung options below are SSD choices rather than standalone hubs.

Which Option Makes the Most Sense?

• Choose HomeBase 3 if you want the most straightforward expandable-storage foundation for your S340.
• Choose HomeBase Professional S1 if storage is only part of the reason you are upgrading and you also value features such as battery backup and 4G LTE connectivity.

  Some high-risk locations may benefit from more than a standard surveillance camera. If your garage, driveway, or entrance also needs strong motion-activated lighting, read our Ring Floodlight Cam Wired Plus review to see whether combining an outdoor camera with built-in floodlights makes more sense for that location than adding another conventional camera.

• Choose the Crucial BX500 1TB if you already have the appropriate HomeBase and want a value-focused 1TB SATA SSD.
• Choose the Samsung 870 EVO 1TB if you want a more premium 1TB SATA SSD and are comfortable paying more for it.
• Do not buy the E40 + HomeBase 2 bundle as an S340 storage upgrade. It is a complete E40 camera bundle, and HomeBase 2 is not the expandable HomeBase path we are recommending for SoloCam S340.

Best Overall for eufy S340: HomeBase 3 (S380)

If your main reason for being here is to give your eufy SoloCam S340 a better long-term local storage setup, our first purchase would not be the most expensive SSD. We would start with the eufy HomeBase 3 (S380).

The reason is simple: HomeBase 3 changes what you can build around the S340. Instead of treating the camera's existing storage as the end of the system, you gain a central hub with expandable local storage and room to choose a compatible drive based on how much capacity you actually need.

That makes it a smarter starting point for someone who owns one S340 today but may add another eufy camera later. You are not locking yourself into a fixed 1TB purchase from day one;

If running Ethernet to every camera location is more installation work than you want, compare the best wireless home security cameras before committing to a full PoE system. Wireless models can make difficult outdoor locations easier to cover when flexible placement matters more than having every camera physically connected to the recorder.

Why HomeBase 3 Is Our First Choice

• It solves the storage architecture first. An SSD does not install directly inside the SoloCam S340. HomeBase 3 gives you the expandable storage hub that a compatible internal drive can be installed into.
• Storage can grow with your camera system. HomeBase 3 supports expandable local storage up to 16TB, giving you considerably more room to scale than relying only on camera-level storage.
• You choose how much storage is worth paying for. A smaller system can start with a modest compatible drive, while a household adding more cameras has the option to move toward substantially larger capacity.
• It keeps local storage at the center of the setup. For buyers trying to avoid making recurring cloud-storage payments a requirement, HomeBase 3 provides a much more attractive upgrade path.
• It adds more than an empty drive bay. HomeBase 3 also brings eufy's BionicMind AI functionality and centralized management for compatible eufy security devices.

Who Should Buy HomeBase 3?

We would recommend HomeBase 3 most strongly to an S340 owner who expects to keep the camera for several years, wants centralized local storage, or expects to add more compatible eufy cameras later.

It also makes sense if you are currently deciding between buying a small SSD and a much larger one. With the storage foundation in place first, you can choose capacity based on your real recording workload instead of guessing how much storage you might eventually need.

When We Would Not Choose It

HomeBase 3 is not automatically good value for every S340 owner. If you are satisfied with the camera's existing recording arrangement and have no interest in centralized or expanded storage, buying another hub simply because it is available adds unnecessary cost.

Connectivity should also be part of that decision. A permanent PoE NVR is ideal when you can run Ethernet back to a central recorder, but remote locations may require a different approach. See our comparison of security cameras without home WiFi if you need phone access at a location where a normal residential Wi-Fi network is difficult or impossible to provide.

Likewise, buyers specifically looking for 4G LTE and battery-backup capability should compare it with the HomeBase Professional S1. The S1 is considerably more premium, but it targets a different problem than simply expanding local storage.

Which SSD Would We Pair With It?

Of the SSDs in this guide, the Crucial BX500 1TB is the more value-focused choice, while the Samsung 870 EVO 1TB is our more premium alternative.

We would not pay more for the Samsung simply because its advertised maximum read speed is higher. For this use case, the buying decision should focus more heavily on compatibility, capacity, endurance, price and the recording workload than on chasing small differences in SATA benchmark speeds.

Which HomeBase or SSD Should You Buy for eufy S340?

The easiest way to make the wrong purchase is to compare every option as if it does the same job. It doesn't. A HomeBase changes the storage and management system around your SoloCam S340, while an SSD is simply the storage hardware used inside a compatible HomeBase.

So instead of starting with brands or specifications, start with one question: What are you trying to improve about your current S340 setup? Your answer usually makes the right purchase much clearer.

If You Own an S340 but Don't Have HomeBase Yet

Start with eufy HomeBase 3 (S380).

Buying the Samsung or Crucial SSD first does not solve the problem because the SSD does not install directly inside the SoloCam S340. HomeBase 3 creates the expandable local-storage foundation, and then you can decide how much additional storage is appropriate.

• You want centralized local storage for your compatible eufy system.
• You expect to add more compatible eufy cameras later.
• You want the freedom to choose your own storage capacity.
• You want a more practical option than jumping immediately to the premium S1.

If You Already Have HomeBase 3 and Just Need More Storage

Your decision becomes much simpler. You don't need another HomeBase just to increase storage. Instead, focus on choosing the appropriate compatible 2.5-inch SATA HDD or SSD for the HomeBase.

If running Ethernet around the property is the main obstacle, a wired NVR may not be the only option worth considering. Our guide to the best solar security cameras looks at outdoor systems designed to reduce charging and cabling demands while still giving homeowners more flexible camera placement.

For the SSDs included in this guide, that puts the Crucial BX500 1TB and Samsung 870 EVO 1TB against each other.

If You Want the Best Value SSD

We would lean toward the Crucial BX500 1TB.

It gives you 1TB of solid-state storage in a 2.5-inch SATA format without positioning itself as the premium-priced option in this comparison. For someone who wants SSD storage but doesn't see a reason to pay extra for a more expensive SATA drive, the BX500 is the more logical candidate.

• 1TB capacity for a meaningful storage upgrade.
• 2.5-inch SATA design relevant to the HomeBase storage setup.
• Solid-state operation with no spinning mechanical drive components.
• A better fit for buyers prioritizing value over premium positioning.

If You Prefer a Premium 1TB SSD

The Samsung 870 EVO 1TB is the stronger fit for a buyer who specifically wants the Samsung option and is comfortable paying a premium.

Its advertised sequential read speed reaches up to 560MB/s, and the Amazon listing also highlights Samsung technologies and its SSD-management ecosystem. But those specifications should not be mistaken for a guarantee that your S340 will suddenly record better video.

You are still buying 1TB of SATA SSD capacity. The reason to move toward Samsung should therefore be your preference for the overall drive, not an expectation that a small benchmark-speed advantage will transform camera performance.

If Backup Power and Connectivity Matter More Than Price

This is where the HomeBase Professional S1 becomes relevant. It should not be viewed simply as an expensive replacement for HomeBase 3. It targets a buyer with broader security-system requirements.

Its appeal comes from combining the central security-hub concept with 4G LTE, battery backup, expandable local storage and advanced local AI capabilities.

If those capabilities solve a real problem for your home, paying more can make sense. If all you want is additional S340 storage, however, much of that extra hardware may provide little practical value to you.

What About the E40 3-Cam Kit + HomeBase 2?

This is the option that requires the most caution in this comparison. The bundle makes sense when the objective is buying the E40 camera system it was packaged around, but it should not be purchased as though HomeBase 2 were interchangeable with HomeBase 3 for an S340 expandable-storage setup.

Why Upgrade Your eufy S340 Storage Before You Need It?

Storage is one of those upgrades that can feel optional while everything is working normally. Your eufy SoloCam S340 detects activity, records events, and you may rarely think about what happens to older footage. The problem is that security recordings usually become valuable only after something has already happened.

A damaged package, an unfamiliar person near the house, a vehicle incident, or activity you did not notice immediately can suddenly make older footage far more important than it seemed when it was recorded. That is a poor time to discover that your storage setup was smaller or less flexible than you wanted.

The Real Opportunity Is Building the Storage System Early

Adding HomeBase 3 is not only about getting more space today. It gives a compatible S340 setup an expandable local-storage foundation that can continue to make sense if your security system grows.

The same whole-system approach applies if you use eufy instead of a traditional NVR. Our guide to HomeBase 3 accessories covers useful add-ons for building a more complete S380 setup, including options that can improve storage, installation, and everyday use as your camera system grows.

You might have one S340 now. Later, you may decide the side entrance needs another camera, the backyard has a blind spot, or the garage deserves separate coverage. Storage requirements can change as cameras are added.

Three Reasons Waiting May Not Save You Anything

• Your security system may grow before you expect it. One camera often solves one problem. Once you identify another blind spot, adding a second compatible camera can change how much local storage is useful.
• Important footage is not always reviewed immediately. You may only realize later that an older event contains information worth checking. A more capable storage setup gives you greater flexibility when reviewing recording history.
• You can choose storage around your needs instead of replacing the whole setup. With an expandable HomeBase approach, you can select an appropriate compatible drive rather than treating the S340's camera-level storage as the final limit of the system.

  Before committing to Ethernet runs around the entire property, decide whether every location actually needs a wired PoE camera. Homeowners who prioritize easier outdoor placement can compare the S3 Pro or S330 to see how solar charging, 4K video, nighttime performance, and HomeBase 3 local storage change the tradeoff between installation flexibility and a traditional wired NVR system.

Don't Wait for a Security Event to Expose the Weak Point

Nobody buys security storage because watching an SSD fill up is exciting. You buy it because recordings have value when something unexpected needs to be reconstructed later.

If you already know that you want centralized expandable storage, delaying the decision does not improve the recordings you are keeping today. It simply means continuing with the current storage arrangement until you eventually decide to change it.

Buy the Upgrade You Need ; Not the Most Expensive One

Urgency should not push you into overspending. If your only goal is expandable local storage for an S340, we would still choose HomeBase 3 over the much more expensive Professional S1 unless you specifically need the S1's additional capabilities.

The same principle applies to SSDs. A premium Samsung drive is not automatically the right purchase just because it costs more. If the Crucial BX500 1TB satisfies your requirements and offers the better value when you buy, paying extra may accomplish very little for your actual security setup.

Our Priority Purchase for an S340 Owner

If you own an S340 and have already decided that you want expandable, centralized local storage, HomeBase 3 remains the purchase we would prioritize first.

It creates the foundation. The SSD decision can then be based on budget and capacity: the Crucial BX500 1TB for the more value-focused route, or the Samsung 870 EVO 1TB if you specifically prefer the premium Samsung option.

Final Recommendation: The Best Storage Setup for eufy S340

After comparing the HomeBase and SSD options in this guide, our recommendation for most eufy SoloCam S340 owners is straightforward: start with eufy HomeBase 3 (S380).

Not every security camera needs centralized NVR storage. Cameras with built-in card slots can record locally too, and our guide to microSD cards for security cameras explains how capacity, compatibility, video-write performance, and recording workload affect which card makes sense for local surveillance footage.

It is the product that makes the rest of the storage decision useful. Instead of buying an SSD and wondering where it fits into your S340 system, HomeBase 3 gives you the centralized, expandable local-storage foundation first. You can then choose a compatible drive based on the capacity and budget that actually make sense for your home.

Already Have HomeBase 3? Add the Right SSD

If HomeBase 3 is already part of your setup, you can skip buying another hub and focus on storage. Of the two 1TB SSDs in this guide, the Crucial BX500 1TB is our value-focused choice, while the Samsung 870 EVO 1TB is the premium alternative.

We would choose between them based on current price, compatibility, capacity needs and the type of recording workload you expect rather than buying whichever drive advertises the slightly higher maximum speed.

Storage capacity becomes just as important in hub-based camera systems as the number of cameras grows. If you also run a eufy setup, our comparison of the best hard drives for HomeBase 3 explains which capacities make sense for smaller systems, growing multi-camera setups, and homeowners who want more local recording history.

When Is the Professional S1 Worth Paying More For?

Choose the HomeBase Professional S1 when you specifically want its more advanced security-center capabilities, including features such as 4G LTE and battery backup. Those features can justify the premium for the right system, but they are not necessary simply because you want more S340 storage.

Our Ideal eufy S340 Upgrade Path

For most readers arriving here specifically because they need more flexible local storage, we would build the system in this order:

1. Keep your SoloCam S340 as the camera doing the monitoring.
2. Add HomeBase 3 to create the centralized expandable-storage foundation.
3. Add a compatible SSD or HDD based on the amount of recording history and camera expansion you actually expect.
4. Increase capacity later if necessary rather than paying for a huge storage configuration before you know you need it.

Prices and availability can change. Check the current product listing before buying and confirm compatibility with your exact eufy configuration.
