io1class of NVMe-based network storage is our flagship storage class. These are NVMe-based SSDs, networked together for maximum random read and write speeds.
st1class of HDD-based network storage is perfect for performant data storage. These are hard drives, networked together for maximum sequential read and write speeds.
io1storage class is optimized for random reads and writes and is the faster storage medium, whereas our
st1storage class is optimized for more capacity at the same cost.
