It was a bit of a impulse purchase and after doing more research I'm not sure the EARS long term reliability in a DVR is something I want to risk. I may return it. Any recomendations? I still working my way thru this thread, lots of good information.
Lots of out of date info too. If you want an HDD that's made specifically for DVRs, the EURS WD HDD is the latest one. Some folks have had problems getting the HRs to recognize them, tho. I have a couple of WD EADS HDDs in my owned 20-700s and they've been very reliable. They aren't built with DVRs in mind, just as the EARS aren't. For the price, you can't beat the EARS.
How reliable will they be in the long run? Only way to know that is to wait a couple years and see if they are still working properly. I know I have one EARS used externally and I might have one internally in one of my other owned 20-700s. Kinda lost track of what's in what. Should have marked them all.
Another really good HDD is the WD EVDS line. They are made for DVRs and really work quite well, but they have stopped production of them and the EURS has taken it's place. If you can find an EVDS at a decent price somewhere, you might consider buying it.
I'd recommend going for the larger 2TB HDDs, they don't cost a lot more than the 1TBs and will serve you better. Any HDD that passes 20-30% available capacity is probably gonna bog down your HR to some extent. The closer you get to full, the worse it gets. A Menu Restart will usually get the HR running quicker again, but you'll find yourself restarting it more frequently. I keep my 2TBs at 50-60% full and have no bogging down of my HRs. This week I'll get another 2TB EARS to replace a really noisy Seagate 1.5TB in an external device. That will give me 20TBs of capacity. I wouldn't recommend anything but a WD HDD at this time.
