If you’re invested in the Eufy security ecosystem, you already know the power and convenience of the Eufy HomeBase 3. It’s the brain of your smart home security system, offering advanced AI features and, crucially, local storage for all your video footage. While the HomeBase 3 comes with some built-in storage, eventually, you might find yourself needing more space, especially if you’re running multiple cameras or want longer video retention. That’s where an eufy HomeBase 3 external hard drive comes into play.
But here’s a little secret: when we talk about expanding the storage of your HomeBase 3, we’re actually talking about adding an internal 2.5-inch SATA hard drive into its dedicated bay, not typically an external USB hard drive. While USB drives are great for general data backup, the HomeBase 3’s primary expansion method utilizes an internal slot for seamless, integrated storage.
In this guide, we’ll dive into some of the best hard drive solutions that either directly integrate with your HomeBase 3 or offer excellent capabilities for managing your security footage. We’ve rounded up a selection of drives, including those specifically designed for the HomeBase 3, versatile 2.5-inch internal options, and even some robust external drives for broader backup needs. Let’s explore the top choices to ensure your Eufy system never runs out of room.

Frequently Asked Questions (FAQs)
Q1: What kind of “eufy HomeBase 3 external hard drive” do I actually need for expansion?
A1: Despite the common term “external hard drive,” the Eufy HomeBase 3 actually expands its storage by adding a 2.5-inch SATA III internal hard drive into a dedicated bay inside the unit. You typically do not connect a USB external hard drive directly to the HomeBase 3 for storage expansion.
Q2: How much storage can the Eufy HomeBase 3 support?
A2: The HomeBase 3 comes with 16GB of built-in storage. However, you can expand this significantly by installing an internal 2.5-inch SATA hard drive, supporting capacities up to a massive 16TB.
Q3: Is it difficult to install a hard drive into the Eufy HomeBase 3?
A3: No, it’s generally very straightforward. Eufy designed the HomeBase 3 for user-friendly installation. You’ll typically just need to open a cover, slide the 2.5-inch SATA drive into its bay, and secure it. No complex tools or technical expertise are usually required.
Q4: Do I need a special “surveillance” hard drive for my HomeBase 3?
A4: While a standard 2.5-inch SATA III hard drive will work, a surveillance-grade HDD (like those from Western Digital Purple or Seagate SkyHawk) is often recommended. These drives are designed for 24/7 operation, higher write cycles, and can better handle the continuous recording demands of security cameras, leading to greater reliability and longevity.
Q5: If I add a hard drive, do I still have to pay monthly fees for Eufy storage?
A5: Absolutely not! One of the biggest advantages of the Eufy HomeBase 3 is its commitment to local storage with no monthly fees. By adding an internal hard drive, you’re simply expanding your local storage capacity, meaning all your footage remains on your device, accessible without any ongoing subscription costs.
Q6: Can I use an SSD (Solid State Drive) instead of an HDD for my HomeBase 3?
A6: Yes, you can use a 2.5-inch SATA SSD instead of an HDD in your HomeBase 3. SSDs offer faster read/write speeds, lower power consumption, and are more durable due to the lack of moving parts. However, they are typically more expensive per gigabyte than HDDs, and their write endurance (how many times data can be written to them before degradation) can be a factor for continuous surveillance recording, though modern SSDs are very robust.
Q7: What happens to my old footage when the storage gets full?
A7: The HomeBase 3 typically uses a loop recording system. When the storage is full, the oldest footage will be automatically overwritten by new recordings. This ensures that you always have the most recent events captured. The larger your storage capacity, the longer you can retain footage before it gets overwritten.
