One other consideration is I've found (at least on the Pi) CPU load is increased when performing heavy read/write activity. Certainly a little more than when I do the same thing through a SATA controller or testing through a Broadcom hardware RAID adapter.
And that CPU load gets a little into the worrisome territory when I put multiple NVMe in a RAID (which I'll be documenting soon!).
- throwaway894345 6y agoIs the CPU load attributable to some NVMe overhead or is it just that NVMe is faster than SATA and thus the CPU is being more efficiently utilized?
- geerlingguy 6y agoThat's a good question, and something I haven't spent enough time benchmarking yet to give an intelligent answer to.
- bullen 6y agoI'm glad to have you poking the ARM space because we're not getting the hardware we need for home hosting. AWS/GCP really need that competition if we want some sort of distribution for the internet at large. I'm still going with Raspberry 2 with 512GB/1TB SanDisc for my live database cluster (redundant not sharded!) as things are now. But really the problem is watts per high quality GB of disk, as in rewriteable bits >1000 times: SLC, MLC, TLC and now QLC (for those uninitiated: single, multi; double really, triple and quad; four layer); it's downhill from here on!
