It should be an ideal workload for SMR disks. Assuming they smartly designed the "plots" which we already know they didn't. Streaming/sequential read only workloads ought to just go right along.

If they were just SMR disks. WD designed them with a CMR portion that is designed to be flushed and written to an SMR area. On the 6TB drives I have my estimate is that the CMR portion is around 300GB. When the CMR portion runs out the performance drops heavily as it is forced to write data to SMR to empty CMR. This poor performance has had larger raid arrays mark drives as defective.

The comedy from the tears looks promising.

Just the tip!

SMR is fine if you're writing huge chunks of data to an empty disk (not a ZFS rebuild mind you, that's not sequential enough) so they're probably just fine for Chia if you're blasting your dumb loving sudokus onto an SSD then moving them.

15K RPM SAS drives plot fine and last forever. It's the secret that they don't want anyone to know.
