An EC2 application uses a 200 GiB gp2 EBS volume. Its storage capacity is sufficient, but it needs more sustained IOPS without purchasing additional capacity solely to increase performance. Which change best meets this requirement?

1. Create more snapshots of the gp2 volume to increase its active IOPS.
2. Increase gp2 capacity to 2 TiB and leave the additional space unused.
3. Migrate the volume to gp3 and configure the required IOPS and throughput within supported limits.
4. Change the volume to st1 because throughput-oriented HDD storage provides the lowest random-I/O latency.
