Frequently Asked Questions (FAQ)
Q1: What kind of hard drive does the Eufy HomeBase 3 (S380) support?
A1: The Eufy HomeBase 3 supports 2.5-inch SATA HDDs (Hard Disk Drives) or SSDs (Solid State Drives) with a maximum thickness of 15mm. It’s always best to check the official Eufy specifications for the latest compatibility information.
Q2: How do I install an HDD in my Eufy HomeBase 3?
A2: Installation is generally straightforward. You’ll need to remove the cover of your HomeBase 3 (check Eufy’s manual for specific instructions), slide the 2.5-inch drive into the designated bay, and secure it if necessary. Once installed and reassembled, power on your HomeBase 3, and you’ll typically be prompted to format the drive through the Eufy Security app.
Q3: What’s the maximum storage capacity I can add to my Eufy HomeBase 3?
A3: The Eufy HomeBase 3 can support an expandable local storage capacity of up to 16TB. This is a massive amount of space, allowing for extensive video retention without monthly cloud fees.
Q4: Do I really need an HDD for my Eufy HomeBase?
A4: While the HomeBase 3 comes with 16GB of built-in eMMC storage, adding an HDD or SSD significantly expands your storage capacity. This is especially useful for continuous recording, having longer video retention, or managing multiple cameras.

SSDs (Solid State Drives) are faster, more durable (no moving parts), and consume less power, but they are generally more expensive per gigabyte. For surveillance, an HDD usually offers the best balance of capacity and cost-effectiveness, especially since the HomeBase’s processing speed isn’t bottlenecked by HDD speeds.
Q6: Will adding an HDD void my Eufy HomeBase warranty?
A6: Eufy HomeBase 3 is designed with an expandable storage slot, so installing a compatible 2.5-inch drive (HDD or SSD) should not void your warranty, provided you follow the manufacturer’s instructions for installation and don’t cause any damage in the process. Always refer to your product’s warranty terms for confirmation.
Q7: Can I use an external HDD with my Eufy HomeBase 3?
