Aside from privacy issues and such, something I haven't seen talked about much is how much space Recall will end up consuming. To quote Ars Technica
- The default allocation for Recall on a 256GB device is 25GB, which can store approximately three months of snapshots. Users can adjust the allocation in their PC settings, with old snapshots being deleted once the allocated storage is full.
25GB of space for something probably 99.999% of people won't use or adjust is quite significant, especially since this is on top of the 15-20GB of space System Restore can use, plus the rather large hibernation file, and page file, and everything else that Windows can use. If you're using a 256GB drive you're going to easily see nearly half of it unavailable, and after you tack on your preferred office, chat, and other "necessary" programs your next step is going to be "buy a larger drive". To quote a table from Microsoft's page on Recall:
Device storage capacity | Storage allocation options for Recall |
256 GB | 25 GB (default), 10 GB |
512 GB | 75 GB (default), 50 GB, 25 GB |
1 TB, or more | 150 GB (default), 100 GB, 75 GB, 50 GB, 25 GB |
If you have a 1TB SSD then by default 15% of your space is immediately reserved for Recall, which is -insane-. Yes you can limit it down, but how many people are going to do this? Probably about the number of people who flush their system restore points and limit its reserved space.
And think about it, if it's only useful for 3 months, then what use is it really? Not worth 25GB+ of space on my disk that's for sure.
