SanDisk Portable SSD 2 To

Bought it for my series X you can only store games on it you can play games from it.

Great price - only one is stock though, at our local store.

Compact ligjtweight device with 3 year warranty. Speedy transfer when used with USB3. Much slower in USB-C.

Right out of the box wouldn't mount and didn't work on other computers - JB let me return and get a Samsung no problem. I should have Googled them first- known problem.

Bought this on sale at JB Hi-Fi for $169 to replace my failing Seagate desktop external hard drive I had for over 10 years. It is both very small, doesn't require external power and is significantly faster being an SSD. I can now backup large files within a few minutes and not hours.
