How Do I Choose Between High I/O and Ultra-high I/O?¶
High I/O: The average latency is 6 to 10 ms, and the maximum bandwidth is 120 MB/s (read + write).
Ultra-high I/O: The average latency is 1 to 3 ms, and the maximum bandwidth is 320 MB/s (read + write).
You are advised to select ultra-high I/O, because ultra-high I/O disks deliver much higher bandwidth than high I/O.
Different bandwidth configurations support different disk types. For details, see Table 1.
