Arris | Dvr Module 500g

If you hate monthly fees and have a compatible Arris DVR, the 500G module wins. If you have already switched to a streaming-first setup, cloud DVR or a network DVR like Tablo is better. Frequently Asked Questions (FAQ) Q: Will the Arris DVR Module 500G work with my Xfinity X1 DVR? A: No. Xfinity X1 boxes (XG1v3, XG1v4, Xi5, Xi6) do not have internal expansion bays. They use external USB 3.0 drives or cloud storage. Q: Can I upgrade the 500GB module to a 1TB drive inside the caddy? A: Technically yes, but it requires opening the caddy (voiding any warranty) and cloning the firmware. Many users have swapped in a 1TB Western Digital Blue drive, but the DVR may only recognize the first 500GB due to firmware limits. Q: I installed the module, but my DVR still shows the same recording space. A: You likely need to reformat the drive. Go to Settings > DVR > Storage Management > Erase Expansion Drive (this will not delete your primary recordings). Q: Does the 500GB module make my DVR slower? A: No. In fact, it can improve performance because the primary drive is no longer handling simultaneous write operations. Seek times remain unchanged (~15ms). Q: Can I use this module with a Tivo or HDHomeRun? A: No. The pin connector is proprietary to Arris DCX and Explorer series DVRs only. Tivo uses eSATA or internal 3.5-inch drives.
