Ignition Gateway Server SSD vs HDD

Ignition

Hi,

I’m looking at sizing a server for an ignition project and was wondering if there’s any reason I can’t have a HDD over an SSD. Trying to keep costs down and there is a significant difference in price.

Thanks

I wouldn’t, especially in Ignition 8.3.

I wouldn't, in any version.

In v8.1 and earlier, certain resources are read from, and any configuration changes have to be written to, a SQLite file in a single-threaded library. Any extra latency there will have an impact on many workloads.
