When using SSD or eNVM, why would local IO be more unreliable/unpredictable than local RAM?

- riskable 3y agoDon't assume your process is the only process. You have to share resources like storage and RAM with everything else on the system. Just a single, simple Java app can gobble up all available RAM if you don't tell it otherwise.
- ngrilly 3y agoExactly. Which means other processes running on the same server can cause latency on disk access but also on RAM, which was the point I was trying to make :)
