I love the “which will last longer” questions. It’s like asking what’s tomorrow’s winning lottery numbers
Data Hoarder
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
You have the numbers ? Be a mate DM them to me 😁
Internally - there is basically zero difference between a usb thumbdrive and a microsd card.
That’s not necessarily true. It all depends on the flash and controller used in the USB drive. There ARE USB drives that are specifically designed for high endurance.
I have a USB stick that’s literally using an SSD controller internally and SSD quality flash. It’s much more expensive than a normal USB drive.
I would also argue that (micro)SD cards have very poor write endurance due to a lack of an internal controller.
I believe (micro)SD cards actually do have a controller. It's also possible to "Trim" SD cards via MMC commands, though this requires them to be accessible directly (i.e. /dev/mmcblk
on Linux).
If you need USB-based storage that should be performant and reliable, there is a no-brainer solution: NVMe enclosure with a medium to high tier SSD. It's really hard to match the speed, reliability, and price of this solution.
All removable media is impermanent. Keep backups.
But realistically, if it is never unplugged and only used read-only as a media source, it's unlikely either will fail in a couple years at least (probably longer). If it fails, just buy another to replace it.
It depends on what USB stick and what SD card.
A high quality "Extreme Endurance" SD card can be expected to last much longer than a random USB stick.
A decent quality SSD, in a USB stick shape, might be even better.
I like SanDisk Extreme Pro Solid State USB sticks. Somewhere in between. Perhaps.
This is just playing media back, right? Keep a copy of the media elsewhere (and, if it's important to you, check that you can access it periodically) and buy the cheapest thing you can find for the TV.
so it will need to last as long as my grandmother does.
We need the S.M.A.R.T data on the grandmother.
Yeah gonna need the power-on hours to make a determination
Neither. I had photos (long since transferred) taken onto an SD card. I recently looked at them after a couple of years to find many of them corrupt. Same for unused usb drives. You need to mount them periodically.
