SMR acts very much like SSD in that to write the data, you actually have to write a large superset of data, not just the block(s) you are modifying/writing, but surrounding blocks as well. This syngas is further decomposed to ammonia, H2, liquid fuels, and methanol. It was earlier proposed that these SMR drives are Drive Managed, but now it seems they are host aware SMR drives. I can't say for every case, but most of the drives using SMR are the larger 2. McKinnon was well represented with 6 teams and many individuals competing for the school. so if you dont write or read in sequential chunks the performance you will get is very bad compared to normal disks.
