I’ve got a 2013 13” Macbook Air with 120g of disk storage. I’ve watched my available disk space drops to an alarming 18g even though my applications are only 9g and my desktop is 14g. I’ve run several disk management programs to clean up the disks but my available storage is 18g and dropping. So now I’m considering my options to get more storage. From what I've read it seem like a good idea would be to get a 128g Transcend Jetdrive. But then putting my applications and my desktop on the Jetdrive will only free up 23g. So I'd appreciate input from those more knowledgeable that myself. Is a Jetdrive my best option? What could I put on the Jetdrive to free up more memory? Thanks in advance.
