Video becomes laggy when I transfer it to my pc and play it.

Yes that will work. If you are using Windows just format it with default settings and choose exFAT for the file system. if you have a mac you will need to use disk utility and you need to set the partition type to MBR (Master Boot Record) and file system to exFAT. Make sure you set the partition type as Mac defaults to GUID partition and the iXpand Drive app does not work with GUID partition types.
