Web22 aug. 2024 · RAID6 (striped double parity) behaves much like its RAID5 brother, but with lower write performances. It has up to 4x the random read IOPS of a single disk, but its random write performance is even lower than RAID5, with the same absolute values (0.5x - 2x) but with lower real word average. Sequential reads and writes are capped at 2X the … WebIOPS – The number of I/O operations completed each second. This metric is reported as the average IOPS for a given time interval. Amazon RDS reports read and write IOPS separately on 1-minute intervals. Total IOPS is the sum of the read and write IOPS. Typical values for IOPS range from zero to tens of thousands per second.
