On: 50TB IBM tape drive more than doubles LTO-9 capacity

Yeah that seems surprisingly good as I thought the write speeds I get from a spinning disk is around 100MB/s or less.

100MB/s or less? Are you using SMR 5400rpm disks? I routinely get 180-220MB/s throughput per Exos drive.

I just ran -

    dd if=/dev/zero of=tmp.img bs=1G count=1 oflag=dsync

And got - 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 9.49586 s, 113 MB/s

The drive appears to be - WDC WD160EDGZ-11B2DA0, it's a 16TB disk, which I thought would be SMR, due to its size, but maybe I'm wrong.

Just found https://www.reddit.com/r/DataHoarder/comments/qf5ar3/is_this... which seems to indicate it's CMR.

This will reduce performance
