Quote from gearmesh :
Not the sellers fault but these should be called 2x7 since its two 7TB drives in one. 2x14 makes it sound like it's 28TB. Does Seagate not understand math?I passed on these and bought one drive. Since my drive is in a NAS and honestlty more speed isn't going to help me as drive speed is not the limiting factor, ny network speed limits my bandwidth.
2X14 is the model name, the "2X" portion is meant to reference performance improvement over the "X14" model.

That the crazy idea to get refurb HDD especially for huge volume
I remember how I was sad when SATA port on mine 4TB Toshiba was broken,I kept there all my family photos and videos...
I replaced the the HDD PCB, which I bought on Aliexpress for $8 and now I am happy.
Anyway I have few more sources to keep copy of my media. but...
Just imagine to get lost 7x2Tb...

I would recommend looking into a NAS. You can get a 2 bay NAS and have the HDD mirrored so when one fails you just pop in the new one and are good to go. you can also get a 4 bay NAS and do Raid so you have either 1 or 2 HDDs fail without data lost (you loose 30% or more in total storage due to stripping).

https://immich.app/ is really good for photo storage on a NAS. Basically google photos for NAS and phones for free

You can even make and old PC into a nas if you look up some instructions on youtube. TrueNAS or unraid are popular options. I like using Proxmox, to run a server and do storage directly in it. its a little more complicated, but very powerful and fun if you like thinkering

it doesn't matter what size the hard drive is, what matters is if you have a backup plan

Quote from Timless :
pretty sure the sata version is a single drive.
you have to partition it correctly to get 2 drives.

the sas is the one that shows up as two drives by default
You are correct.

These DO NOT apply to the SATA version. It will present itself as one 14TB logical drive. If you wish to leverage both actuators simultaneously, you'll have to partition it in half and put both into a RAID configuration. From what I hear, doing so is much easier in Linux than Windows.

Would this work for TrueNAS in ZFS Raid-Z2?
I have 6 bays, if I get 6 drives, TrueNAS will see it as 12 drives? If so, what if I get 3, will it works as RZ2?

Quote from jijacob :
Twice the actuators to fail? I wonder how reliability is on these. I am in the market for NAS drives but these feel risky.

Um that's not quite how that works... If your car has twice as many parts as another car, it doesn't mean you get twice as many failures. You should never have your data in a situation that relies on a hard drive not to fail. If you are backing up your data, then it's not risky at all.
