Hi Paul,
Regarding
o 5TB Costco Item #3005555 P/N 2R2AY1-570 (STHP5000600 on sticker)
o 8TB Costco Item #8888881 P/N 1XAAY5-570 (STEL800401 on sticker)
Here are photos I just snapped for you of the two Costco drives:
o <https://i.postimg.cc/MpjQMNM7/hdd01.jpg> size & weight difference
o <https://i.postimg.cc/5tdFwgLZ/hdd02.jpg> Costco packaging
o <https://i.postimg.cc/76XGrydk/hdd03.jpg> Model numbers
Thanks for that purposefully helpful information where I must comment that
the sheer physical size & weight difference of these two Seagate devices is
immense.
o The 5TB Seagate drive weighs a puny 7 1/4 ounces all alone
o The 8TB Seagate drive weighs a whopping 30 1/2 ounces all alone
<https://i.postimg.cc/MpjQMNM7/hdd01.jpg>
Side by side the sheer physical size difference is also huge:
o <https://i.postimg.cc/5tdFwgLZ/hdd02.jpg>
These are the respective model numbers of the two hard drives:
o 8TB Seagate Backup Plus Hub P/N 1XAAP3-500 [aka Model SRD0PV1] 12VDC, 1A
o 12VDC 3.0A Schenzhen Honor Model ADS-40J-12 12036EPCU Switching Adapter
o 5TB Seagate Backup Plus Portable P/N 2R2APM-505
o <https://i.postimg.cc/76XGrydk/hdd03.jpg>
What I love about the 5TB is it doesn't require an additional 12VDC power
supply, which means, I would think, perhaps, maybe, it's more likely to
work in a decade or so, but I'm not sure of the correct logic on that.
Which is more likely to work in a decade or two from now?

I do not know how tall the 5TB drive is, inside.

The possibility of being "shucked" makes a difference because we want this
drive to work in a decade or two from now.

1. I went to the Seagate warranty page
<https://www.seagate.com/support/warranty-and-replacements/>
2. I enter the 8-character serial number from the Costco sticker.
3. Your Product = Backup Plus Portable <== this is the 5TB
Model Number = STHP5000600
Serial Number = xxxxxxxx
Warranty Valid Until November 29, 2021
Your Product = Backup Plus HUB <== this is the 8TB
Model Number = STEL8000401
Serial Number = xxxxxxxx
Warranty Valid Until October 10, 2022
I'm not so much worried about warranty as I am the basic stone cold logic
of which drive is most likely to be still working a decade or two from now.

Hi Jerry,
Thanks for trying to help, where I apologize that _time_ is the issue.
o Not rotation time.
The drives will likely have fewer than 100 hours on them in 25 years.
While I completely understand your answer, you have to remember these
drives are _external_ drives, connected via USB, for _backup_ purposes.
Hence, rotation time isn't an issue in and of itself.
o Elapsed time is the issue (and technology changes).
Given how standards change, and the fact the 2.5 inch "portable" drive
isn't the same mechanics as the 3.5 inch "hub", and given SATA connections
and other changes over time, the question is simply one of how to choose
between them.
I apologize for not being clear that rotation time is never the issue for
backup drives (which are only connected once every few months, and even
then, for only a few hours at a time).
What matters is the technology changes that may likely occur over time, and
the reliability of the equipment over long periods of elapsed time in
storage.
I'm not so much worried about spinning time as I am the basic stone cold
logic of which drive is most likely to be still working a decade or two
from now after being stored (and while technology changes over time)?
