Runtime filesystem consistency checking

Runtime filesystem consistency checking

Contemporary 4TB HDDs are especially slow because they use 5 plates (where your 1TB disks probably used 2 or 3). This means that not only you see the slowdown from growing number of tracks, you see additional slowdown from growing number of plates!

Thankfully in this direction 5 is the limit: I doubt we'll see return of 30 plates monsters like the infamous Winchester… all 3.5" HDDs to date had 5 plates or less.

Note: you can avoid this step in the future by logging into your LWN account.
