New HDDs (as of 2016) have 2 instead of 3 screwholes on left and right side, problem with disk trays
We just upgraded our RN 104 with 2 new 8 TB disks: Seagate Archive HDD v2 8TB, SATA 6Gb/s (ST8000AS0002)
They are working fine, but I was having problems fixing them to the disk tray. New HDDs seem not anymore to be fitted with the middle screw hole on the sides, where a nozzle of the plastic tray of the RN104 should fit in.
In some FAQ here I found the advice to remove the plastic part of the tray and fix the disk(s) with screws. Actually I would have been able to mount only two screws at the bottom side, where screwholes from the tray and the disk matched. But I did not have matching screws in my PC screws box, they were all either too long or having the wrong thread.
So I fixed them without screws. After taking the plastic part out of the tray, I removed the two nozzles using a knife with serrated blade, leaving a very small bump, put the plastic part back in and fixed the disk. It is very firm and quiet in the tray now.

I did some research before making the choice. The disadvantages of Archive HDDs are: 1. compared with other recent HDDs, they have lower writing speed because they have to read data from nearby cylinders before writing (but compared to older HDDs they are not "slow" at all), 2. they have a transfer limit in "terabytes per year" which can void warranty if exceeded.
Both disadvantages are not important in our scenario. Our NAS is an archive, where lots of data is stored and rarely accessed.

Writing to track 1000 destroys the content on track 1001. So you not only need to read track 1001, you then need to write it. That destroys track 1002. So the drive needs to "ripple" the writes until it reaches an unused track (or the end of the drive). The drive takes care of this automatically.
But sustained write speed is therefore extremely variable and geneerally much slower than older hard drives. There are some other implications - the drives will ignore spindown if they are in the middle of "rippling" the writes.
Also there have been some linus driver issues with these drives. I'm not sure if they are all resolved yet.

Just unwrapped the NAS 214 and 2 Seagates Ironwolf 6TB - compatible per list. Issue inserting hard disks. Reason I see now is that Seagate has 2 holes in meantime (1 top, one down)
Plastic in slider has 2 ( 1 top one middle)
This makes it impossible to insert it easily. What is NETGEARS recommendation what I should do?

Based on https://kb.netgear.com/20641/ReadyNAS-Hard-Disk-Compatibility-List, NETGEAR's recommendation is: "To mount the disk to the desktop NAS disk tray, remove the plastic mounting bracket from the disk tray and use two screws to secure the disk to the disk tray."
