Synology DS1019+ high SSD Cache usage?

Following your excellent video's I installed a 256gb nvme in my plex server. Although I have 15tb of storage 80% used. The DSM has never used more than 6% of read only cache. Something has changed since using I've stated using the DVR function with a HDhomerun. Interstingly my cache use has now increased to 145gb used. Anyone know why this has suddenly risen. I thought DSM would only cache files used more than twice.

This could be something to do with incoming data (write cache). Plex streaming would only read from the cache. But when recording somthing, data is first writtent to the cache before it is stored to the HDD array.

I hope this helps.
