Is sequential IO dead in the era of the NVMe drive?

I wish that it was easier to trim unused unpartitioned space. I find myself fumbling on BSD and Linux trying to remember how to get the exact offsets for that. You could write zeroes but there isn't a guarantee that the FTL will interpret that as unused.

Just make another partition for the unused space, and run blkdiscard on it?

Right, and you can use fdisk and gdisk to see the partition table and determine the offsets

I might put together a script for that because of the danger of making a mistake on a live system.
