I've been rethinking upgrading my new 2TB Edge with a larger 2.5 drive. I've learned the largest 2.5 CMR drive tops out at 3TB. I wanted to go at least 4TB. So now I'm considering the external drive upgrade option. So now that I have 3.5 options to consider I'd like some opinions/advice/results on if the W-D Purple surveillance drives are good-or even suitable for Tivo duty. I've always used AV-GP green drives in my Premiere and Roamio upgrades but WD has apparently stopped producing that line of drives a few years ago so it's hard to find a new-in-package 6TB-the size I would like to use if I go the external hard drive solution. OK Tivo Community, advise/educate me 🙂 Thanks in advance for any thoughts and advice.
