Torrents suck for SSD lifetime, the chunk size is typically 16kb but chunks aren’t downloaded whole and in order, so you might end up with a lot of wear and tear unless the file system and the torrent client/library are both working together to eliminate the partial writes.

However, it doesn’t seem that torrents are a common factor in user accounts, and 30GiB in torrents would not account for that much write amplification, so carry on!
