Patriot Memory P210 1 TB Solid State Drive, 2.5" Internal, SATA (SATA/600)

I installed this 1TB Patriot P210 in my Eufy Homebase 3 to handle local storage for my security setup (5 cameras and a doorbell). Installation was plug-and-play, and so far, it hasn't skipped a beat. The read/write speeds are plenty for multiple simultaneous streams. 1TB is a great starting point, though depending on your recording settings, you might want to scale up later. For the price, it's a reliable way to ditch the cloud subscription.
