Cheap but reliable external SSD for RPis (lemmy.today)

Hello, it's me again. I read a lot about how unreliable micro SD cards are if you use your RPi to selfhost some stuff. Now I wanted to ask if some of you might have recommendations for cheap but reliable external SSDs. I did some research on Amazon but there are some brands I never heard before (Intenso, SSK, Netac, etc.) and don't know if they can be trusted.

Which Raspberry Pi do you have? There are some very reasonably priced M2 hats out there that you can boot from on the Pi 5, including the Raspberry Pi branded one.

But an M.2 is usually more expensive than a normal 2.5" SSD. Is it better to boot from a M.2 HAT than from USB?

M.2 would technically be the best performance available, but realistically I don't think you'd notice the difference over a USB SSD. Maybe a few extra seconds on boot.

Okay and what about longevity of the drives? That should just depend on the number of writes, right?

I'm not sure what kind of money you want to spend? The M2 Hat is ~$14 USD and a 2242 NVME SSD can be had for ~$30-$40 USD since you don't care as much about performance.

The USB to SATA adapter is going to run ~$10 USD and the SATA SSD drives are going to start ~$20 USD are go up from there depending on size, performance, etc.

If size of storage is an issue, the SATA SSD is probably the better route. I believe the NVME would be better performance since it utilizes the bus on the Pi more fully.

I would guess that for the money, most M2 drives and SATA SSD drives are going to be similar lifespans
