People doing CI? Or MDM?

Not sure how either of those would be critically impacted by a 1-2 second data loss in a power failure.

I believe it’s at least 5s. Marcan didn’t specify how long it was, but gave an example of at least 5s. That could cause a device to think it’s allowed to do something via MDM but not actually have a record in the database allowing it to do so.

You don't just lose seconds of data. When you drop seconds of writes, that can effectively corrupt any data or metadata that was touched during that time period. Which means you can lose data that had been safe.

Perhaps.

> MDM

I’m sure my IT department’s spyware will recover just fine.
