That type of USB flash is one of the cheapest kinds of storage and least reliable.
They’re good for a quick copy between computers, but not for reliable storage or backup.
You would be better off being paid by Google, Nielsen, or other ad tracking companies.
It was paid $45 a month for years by Google to track my internet. They gave me a custom router to do it. It was all my own traffic, so I didn’t worry about shady outside traffic. Figured Google already tracked me anyways so I might as well be paid for it.
I would not use NTFS.
Do the reverse. Use ZFS, Ext4, or Btrfs. Those are native Linux file systems.
Then you share the Linux folder with Windows over SMB, which is a Windows file sharing protocol that both Linux and Windows understand well. Voila, copy and paste between both machines without worrying about corruption.
No, you want Ethernet not fiber.
Your downstairs router, computers, and your new upstairs switch / Wi-Fi access point are all guaranteed going to be RJ45 Ethernet.
The only part that is fiber is the part running to the outside.
You can put both a fiber and CAT5E/6 Ethernet in, but just a fiber connection will not accomplish what you want. You need the Ethernet connection in order for each floor to have its own wired connection and/or wifi access. That’s what the consumer equipment will use. Otherwise, you will need more enterprise-level equipment and that will add unnecessary complication.
There won’t be any damage. Worst case, the video files might get deleted.
SD cards are considered one of the least reliable forms of data storage. They wear out quickly compared to things like SSDs or hard drives.
There can be differences between different SD card brands and manufacturers. Sometimes things labeled “high endurance” can be just a firmware difference in the same physical device. Although, that may offer some improvement.
Overall, most quality SD cards from reputable brands (not the cheapest) work okay. If you’re worried about losing footage, connecting the camera to a local NVR (computer that saves video recordings) is the next step up in reliability.
Serve The Home forums and YouTube is dedicated to these devices.
Protectli, CWWK, Topton are the manufacturers. Protectli is actually a rebrander of the Chinese products for western audiences. CWWK designs the actual motherboards. You can order from whichever vender you like, although Topton seems the least reliable as far as English support and firmware.
No such thing as long term SSD storage.
All SSDs leak elections. Putting more bits in a cell can potentially make it easier to lose data, but that’s why we use RAID to check, and backups if things go wrong. Realistically, by the time your SSD starts failing, you can buy a new replacement that’s cheaper. High density is where all the manufacturing savings are. It doesn’t make a lot of sense to spend more for SLC when you can get faster, larger, cheaper SSDs and replace as needed.
