I have a WD portable HD from 2011 with 500 gb on it. It works fine, but looking to upgrade to something with more storage and am considering a desktop version vs. portable. I have a few questions though: 1. Is there a clear benefit of desktop vs portable? I have a rMB with the one port, so I am thinking having a desktop version is best so when I connect to the external HD it will charge while transferring data (I could be wrong on that not sure if thats even possible). 2. I was thinking of using it as just storage. Not using time machine or whatever because that to me gets confusing. Not sure if its possible to just drag and drop photos, documents, etc. If you recommend time machine then I would just do that. 3. Was thinking of these 2: https://www.lacie.com/personal/porsche-design/porsche-design-desktop-mac/ https://www.wdc.com/products/wd-outlet/my-book-for-mac.html#WDBYCC0020HBK-NESN However I assume I would need a usb-c to usb adapter for this to work? 4. Any other recommendations would greatly be appreciated.
