Short stroking helps get more performance from the disk, at least in terms of latency. The bandwidth change occurs because the density is fixed and there are more blocks on the outer rings per track compared to the inner rings so in one revolution you can read more tracks and you don't need to change tracks so often.
You parent comment is right though, there are only small changes in bit density on the track in recent years so the bandwidth is not improving by much.
- hinkley 10y agoSo we went from 1TB to 8TB disks just by packing 3x as many tracks onto drives? I find that hard to believe, and the benchmarks agree with me. You don't double the write throughout on a disk by doubling the number of tracks. You need more platters and/or sectors per track to do that.
