Or am I simply describing that phenomenon, where writes get smudged and, on the basis of "if you can't beat them join them" shingled disks deliberately do exactly that.
This reminds me of the old daze when I used SMD rack-mounted disks, maybe in the late 1980's. The process of reading/writing sectors would, over time, cause them to wander around their tracks. After a period of time, the sectors would start to overlap themselves, leading to all kinds of chaos. The only solution was to do a low-level format and restore the data from 9-track tapes. As long as I'm reminiscing, I also remember open-platter HP disks in the 1970's that required a manual cleaning of the heads with alcohol once every thirty-days. How far we've come! I just fired up a RAID 6 array of 24 10TB Seagate disks. They're working perfectly so far, and they're not shingled! I'm getting about 1.9-GB/sec of continuous write bandwidth.
