I agree with getting SSDs from different vendors, for the following reason: I once had a FreeNAS system fail. It was using two (mirrored) SSDs to hold the OS. One SSD failed; while I was procuring a replacement, the second failed.

I later found that both SSDs were from the same batch, which (I think) is why both failures happened so close together. Purchasing same-size SSDs from different vendors (with similar product lines) helps ensure you're using SSDs that should hopefully fail at different times.

This was common knowledge on the internet before the "modern web" era. Never use in a RAID disks from the same vendor. When you have to use disks from the same vendor try hard to get different type/ batches. And backup.

I very intentionally bought two Samsung ssd from different countries, so I would get different batches. They show up on my door. Same batch, only a few hundreds apart in their serial number :(

If you had tried to get two that close in production, I think you’d have struggled. I didn’t bother and got drives off the stack and bought both, and they are a long way apart.

Wrong. The advice is to use the same vendor/model but from a different production run (batch).
