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.
- hulitu 5y agoThis 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.
- codechad 5y ago> Never use in a RAID disks from the same vendor. Wrong. The advice is to use the same vendor/model but from a different production run (batch).
- wheybags 5y agoI 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 :(
- lostlogin 5y agoIf 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.
