Amazon starts offering "Prime Photo" for Prime members. RAW is also supported, upload without resizing or compression

Amazon Japan has started offering Prime Photo , a service for Prime members

Prime members , so it costs an annual fee of 3,900 yen (including tax), but what's amazing is that it supports RAW, and you can use it without resizing, without compression, and with unlimited storage!

Google Photos was released in May 2015
as an online photo storage service with unlimited capacity Google Photos is available for free, but there are restrictions such as uploaded images being compressed and images larger than 16 million pixels being resized.

If you are considering image management using an online photo storage service and are already a Prime member, Prime Photo be your only choice?

One thing I'm worried about is whether there will be unlimited capacity permanently in the future.
There are some services from other companies that claim unlimited storage at the beginning of their service, but they no longer offer unlimited storage along the way, so I would like to see Amazon do their best.
