General practice in embedded is to avoid writing to disk as much as possible. Data collection is mostly done by sending it to the cloud for storage there. However 'edge processing' and 'edge storage' are hot topics, so there will probably be more work in this area. Some of the surveillance camera vendors are showing interest in this, since it would be beneficial to reduce data needed to be sent. Especially since vast majority of the data is never looked at, or only looked at once (human/machine event detection). But one has the (fundamental?) problem that the sensor is often installed in an adversarial environment. Would be sad to try to pull data after a crime, only to realize the camera storage was destroyed.
