A: The Eufy HomeBase 3 is compatible with 2.5-inch SATA hard disk drives (HDDs) and solid-state drives (SSDs). You’ll need to connect them via a USB-A to SATA adapter/enclosure as the HomeBase 3 does not have an internal bay for direct installation.
Q2: What is the maximum storage capacity supported by the Eufy HomeBase 3?
A: The Eufy HomeBase 3 supports an impressive maximum storage capacity of up to 16TB (terabytes) when using an external 2.5-inch SATA HDD or SSD. This is a significant upgrade from its built-in 16GB eMMC storage.
Q3: Do I need an external enclosure for a bare 2.5-inch drive to use with HomeBase 3?
A: Yes, you will definitely need an external USB-A 2.5-inch SATA enclosure or adapter to connect a bare hard drive (HDD or SSD) to your Eufy HomeBase 3. The HomeBase 3 provides a USB port for connecting these external storage devices.
Q4: How do I install and set up a hard drive with my Eufy HomeBase 3?
A: The process is quite simple:
1. Insert your 2.5-inch HDD or SSD into a compatible USB 2.5-inch SATA enclosure.
2. Connect the USB cable from the enclosure to the USB-A port on your Eufy HomeBase 3.
3. Open the Eufy Security app, navigate to your HomeBase 3 settings, and then to “Storage.”
4. You should see the connected drive, and the app will guide you through the formatting process. Once formatted, the HomeBase 3 will automatically start utilizing the expanded storage.
Q5: What’s the difference between using an SSD and an HDD for HomeBase 3, and which is better?
A:
* HDD (Hard Disk Drive): Generally more affordable per gigabyte, offering larger capacities at a lower price point. They have moving parts, making them slightly more susceptible to physical shock and typically slower.
* SSD (Solid State Drive): More expensive but much faster, more durable (no moving parts), consume less power, and operate silently.
For HomeBase 3, an SSD offers slightly quicker footage retrieval and superior longevity, especially with continuous writing. However, an HDD is perfectly adequate for surveillance storage if cost and maximum capacity are your main concerns.
Q6: Will adding a hard drive affect my Eufy HomeBase 3’s performance or speed?
A: Generally, adding a hard drive will not negatively impact your HomeBase 3’s core performance.

A: No, the Eufy HomeBase 3 is designed to work with 2.5-inch SATA hard drives (HDDs or SSDs). 3.5-inch drives are physically larger and typically require external power, making them incompatible with the HomeBase 3’s design and power delivery for external storage.
