I'm trying to decide between the WD SN7100 and the WD SN850X, both being 4TB options. The SN7100 is priced at $555 while the SN850X costs $590. For me, durability is the most crucial factor. I'm curious whether the extra $35 for the SN850X is justified, especially regarding the importance of DRAM in these drives. Would I actually notice a difference in everyday use?

The SN7100 is actually a great choice! The performance is pretty similar to the SN850X in most scenarios. DRAM is only crucial for intense workstation tasks. For regular use, you won't notice much of a difference.

I totally get it, paying $550 already feels like a lot. But consider that the difference is minimal in practical terms. Unless you're using heavy workloads, the SN7100 should serve you just fine. It's a good option if you're on a tight budget!

Honestly, I would spend that extra $35 and go for the SN850X. Even though you might not see a noticeable difference in regular use, it's a solid investment for better durability and performance in the long run.
