What is more reliable external USB 2.5 or internal SATA 3.5 hard drive?

Question

Backup

The screw with the home archive failed. Work, projects, photos, videos, documents, etc. Everything is gone. The screw lies, I will give it to the workshop.
I found another used one on the shelf. screw, thought about temporary use. Uploaded there projects 2-3 months. In general, the second hard drive had bad sectors, I don’t even know what I was thinking. Also broke. In general, there are tears, scandals, disappointments in the family.
Now I hope I'm a little smarter. Decided to buy 2 hard drives.
I will put the 1st in the PC as disk D:
the 2nd will be external for storing backup copies of the first disk.
And so on a role of the 2nd disk I have a question to all GURU. 3 options:
1st external USB 3 drive form factor 2.5 ( Samsung M3 Portable 3.0 4 TB USB 3.1 ) - 6600 ₽.
2nd internal but using an external box with a direct connection to a PC via USB or in the future to connect to a router (NAS) ( Toshiba P300 3 TB SATA ) - 5300 ₽.
3rd external Seagate Backup Plus Hub 4 TB USB 3.1 - 6900 ₽.
The unit cost of a gigabyte is about the same. But they have different form factors.
1st is more impact resistant. 2nd and 3rd are faster. In this context, both advantages are equivalent. Shock resistance is equally important as speed. In this case, it is important to store data for a long time.
.
Is there a more precise concept or knowledge that one of these disks stores data for much longer.
For example, if I write information to a disk and connect it in 10-20 years, then the disk will be operational, but the data may already be partially lost due to demagnetization and the lack of resumable overwriting.
.
PS: SATA disk can be used later in the NAS in the future. but there is one thing. it is not advisable to constantly keep the connected disk to the router for copying once every 2 months. Today, routers do not have firmware to be able to use the router as a file cloud. Of course, if you connect a white IP for the router, then forward the VPN, then dance with a tambourine, you can make a file cloud. These dances with a tambourine kill, 2019, and USB routers have not learned how to work like a cloud, without any white IPs, without VPN forwarding. Yandex Disk and CloudMailRu does not require VPN settings and everyone uses it.

Answer 1

Consumables.
Irrelevant.
No. These are consumables. All drives are consumables. The fact that the drive allows you to read what was previously recorded is nothing more than an accident. You will not suddenly lose data only if you accept this thought. For important data, 3 or more copies on different drives is the norm. including geographically dispersed.
On the horizon of saving data in decades, the problem has no solution at all. Yes, this is the problem of the modern world.
There are no shock-resistant HDDs. Purely by the physical device of this class of drives.

Answer 2

A shelf.
Buy yourself an entry-level Synology with two drives, mirror them and use them. The probability of failure of two disks at the same time is noticeably less than one :) The shelf itself costs a penny, the disks will pull the most, because taking desktop ones is the wrong decision, you need to take raid ones.

Answer 3

What is more reliable external USB 2.5 or internal SATA 3.5 hard drive?

Certainly internal.
The outer one is constantly dragged, dropped - they live a maximum of a year. And the inner one, as a rule, is not subjected to carrying and shaking.

Is there a more precise concept or knowledge that one of these disks stores data for much longer.

If we get lucky.
Nobody knows when the disk will break - in a week after purchase, or in ten years.

and routers with USB have not learned how to work like a cloud, without any white IP, without VPN forwarding

You wrote something incomprehensible.
Router - a program or device that routes traffic between networks, a gateway.
Cloud - a service for providing infrastructure or computing resources.
What does the router, whose task is to send traffic along the desired route, have to do with services?

Answer 4

My opinion.
The router is designed to route traffic. Connecting disks to it is unacceptable. It's just purely in terms of processor speed that it can't work normally with them.
For the "cloud" is always going to a separate "machine". For example, with the same Nextcloud software. Which, if you have an external IP, will be able to provide you with sending data from smart to the "cloud" online. Actually, this is what mail ur, Yandex and so on do, it's just that they have self-written software for the cloud.
By storage. Keep one copy on any external drive, connect at least once every six months.
Store the second copy in the cloud - you can do it yourself, you can take it ready. For example, on the same hetzner...
Here is the lease https://ru.hetzner.com/hosting/produktmatrix/roots...
Here is the finished cloud, just pay and besides your "personal".

Answer 5

Samsung seems to have a Seagate spindle. Toshiba drives are considered to be more reliable. Many call Hitachi the most reliable.

Answer 6

At home network storage with raid1.
According to the external disk, some thoughts are like that.) The
answer is external on the toaster
