I am using google drive as of now for storing the pictures. I have pictures which is of 26 mp so google drive is compressing and removing the quality of pictures. Is there any other storage quality pictures without compressing? mostly looking for larger storage above 1 TB?
I personally use Amazon Prime. This package come with Amazon Photos which give unlimited storage for images. And by images Amazon understand not only JPEG, PNG, TIFF but also PSD, CR2, ARW and a lot of other RAW formats. And in to the same package you have 5GB of storage for other files (I use it to store XMP files :) )
Plus I store second copy of my photos on local NAS storage with RAID5 config.
Backblaze have a 'B2' service which is basically just rented space, use as you like.
I don't have B2 myself, though I do use their regular backup service & have done for years. All my photos are on there, though I keep them all locally too & use them as backup rather than remote storage.
All I can suggest is look at their advertising & make up your own mind. This is their media-centric ad page - BackBlaze B2 Media & Entertainment
They claim to be far cheaper than the competition too.
Flickr's paid option at $50 a year offers unlimited storage. Although the images will be compressed and sized for display on the site, you can always download the original file. But note that they don't support RAW files, as they are primarily a photo display service, not a storage service.
If you are technically inclined you could get just basic file storage from Amazon's S3 service. There isn't any built-in way to display images, but you can store any kind of file. The costs are a little complicated - uploads, downloads and then month to month storage cost different amounts. But just basic storage is $0.023 a GB a month (up to 50 TB). There are other plans, including "AWS Glacier" which is as low as $0.004 a GB, but accessing the files isn't as convenient, I think.
