My 4 1/2 year old Directv Genie`s hard drive was failing. Freezing, pixilation, it was well worn from constant use. The older model Genie HR54`s have an eSata connection for connecting an external hard drive. While there are complete externals available, the hard drives installed are most likely standard desktop units. These purple`s are designed for constant power on read/writes, and 5400rpm models run cool. Speed is sufficient, 7200rpm models not needed for DVR`s. I purchased a used G-Technology G-DRIVE 3.5" external enclosure minus it`s hard drive. Popped in a 2TB WD Purple, and for around $100, a complete unit was had. Double my original capacity too. Once connected, the Genie automatically formatted, and configured it. The internal hard drive is now incapacitated, the external taking over. It`s quiet, quick, and all the issues I had have vanished!

It’s a beast . After All the talk about how Noisy the big, heavy duty drives can be I was pleasantly surprised that it is relatively quiet. And hoping for a longer Life expectancy in this heavy duty drive in my video recorder .

Very easy to upgrade my Lorex NVR Model N843A8. It fit perfectly and worked like a plug and play device. It only requires a quick format after letting the system fully boot up. It started out a bit noisy but quieted down about 20% after a few days of recording. I discovered most of the noise is being made is due to the hard drive being directly mounted to the NVR case which is thin sheet metal that actually amplifies the natural vibration and clicking that spinning hard drives make. I believe this could be resolved by a soft mount, stiffening the case and rerouting the ground the hard drive makes while in contact with the NVR case. I blame the noise on Lorex and not the hard drive for this reason. The only reason I gave it 4 stars instead of 5 is because playback doesn't flow in sync with multiple cameras or at real speed, which makes calculating vehicle or aircraft speeds between markers impossible. Sometimes the recorded video playback of multiple cameras do not sync in time and may be separated by just a few seconds. I do however believe this may be a firmware issue with the Lorex NVR but have no way to prove it other than to say the original hard drive did the same thing and that's mainly why it was replaced. It was a good value for the money until the 24 to 36% Trump tariffs kicked in. As an alternative storage method I highly recommend the Samsung 870 QVO SSD.

My brothers Tivo Roamio stopped working, and turned out to be a failed hard drive....after 10 years. I installed this new 2 TB drive in the unit, booted up, formatted itself, and all works well! You do have to run through the set up again, and you lose all your old, saved programming, but there is no reasonable way around that.
