Hi, running I stripper now from a NAS as I do want a backup in case the drive fails. Lots of downloading time it will be with the collections.
Few things to consider do.
Quality of cards? I still run my downloads in 1080. I have premium which offers 4k, but my pc (although nice stuff and great gaming machine) is not supporting 4k. It mostly is the screen. So think about disk space. Do you really see benefit with 3k? Or is 1080 good enough? It saves disk space.
Further a bit more clear:
Click on the radar icon in your Istripper app. Right upper corner
Scroll down to data as stated in above comments.
Note that you can add multiple locations now. So you can still keep the old drive and use the new for more free space
Otherwise perhaps keep it as backup and just copy the data to new harddrive. Then add after copying this drive onder data.
make sure you map to the models folder. This includes DATA and models.
Good luck!
