825GB because it's a really nasty way of the whole GB/GiB thing.
The PS5 (original) has 6 128GiB chips for 768GiB total storage. Normally, such an SSD would be called 768GB, hiding things like bad blocks and data tables in the difference. When you buy an SSD like that, that's where the difference goes.
So if you buy a 250GB SSD, you can be sure it has 256GiB of NAND flash inside, but appear with 250,000,000,000 bytes of storage. The difference holds the bad blocks, spare blocks, and data tables.
If you haven't figured it out, 768GiB is about 824.9GB so its even rounded up to 825GB. And your actual storage WILL be less, because that's not accounting for again, bad blocks, spare blocks, and data tables.
Most SSDs would be listed as 768GB, 760GB if they had the same configuration.
The 1TB PS5s would have 8 chips of 128GIB for a real 1TiB of storage, but rounded down to 1TB because that excess is used elsewhere.
