Value: General ESSD provides three key features: I/O burst, I/O acceleration, and data archiving. Compared with ESSD PL1 on RDS, General ESSD costs less than 70% for storage but can achieve up to 200% throughput performance, offering great value for money. Currently, this type supports both ApsaraDB RDS for MySQL and ApsaraDB RDS for PostgreSQL.
