A:AnswerSadly there are none with more storage right now, but the storage WILL be expandable with SSDs in the future that Sony will test themselves and say they are compatible with the system. Look at 2:45 on the link with subtitles and they show where the internal slot for this is, and don't worry, taking off the side cover wont void the warranty. They intended it to be removable. You only void it by removing the stickers UNDER the first cover. https://youtu.be/CaAY-jAjm0w?t=164
