Answer: Change the volume type from gp2 to gp3.
gp2 volumes provide 3 IOPS per GB with burst credits. For 500GB, baseline is 1500 IOPS, bursting to 3000. When BurstBalance hits 0, sustained 3000 IOPS isn't possible. gp3 provides consistent 3000 IOPS baseline for any size up to 16TB at lower cost than io2 or larger gp2. st1 is for throughput not IOPS. Doubling to 1000GB gives 3000 baseline but costs more than gp3.
