They're really all about the same honestly. I'd buy the one that looks nice to you and fits in the budget. I will say though that you need to be sure to back this drive up. If you're more paranoid you could get a dual-bay RAID enclosure that offers a little more redundancy. Better yet, get a NAS.
This new integration with the Veeam Data Mover Service (VDMS) enables DXi deduplication appliances to support the full breadth of advanced Veeam features such as synthetic full backup creation and instant VM recovery. The two companies state that using Veeam with DXi deduplication appliances can both maximize availability of production environments while minimizing backup storage costs. Aside from the above mentioned benefits, DXi appliances will also be added to the Veeam user interface in the next software release.

The levels of variety give OEMs lots of flexibility as they create data center gear.
WDC Announces HGST Ultrastar SAS SS300 SSD
Intel wants "Optane Memory" to be used with their cache software, though you can use it without as a tiny SSD if you want. I'm just saying I think the idea is dumb and they should have just waited to launch a proper SSD. That's probably what Micron will do, instead of trying the interim step that Intel is taking. My read is that the Optane media is just not ready for prime time yet but Intel is trying to build it's brand in the interim.
If it's me, I'd just buy on price at the capacity point you want to hit. In quantity of one, it won't matter. Personally, I prefer HGST, but again, everyone has their favorite/horror story. Just back up whatever you buy and all will be good.
It's something we've considered but don't have a great answer. In our lab, we don't hear any of them, but we have 5 racks of gear I do understand though if you're putting a NAS anywhere other than a closet or basement, noise may be a concern.
