In the case here, space efficiency could be better while sequentiality is quite high.
在这个示例中，当顺序性很高的时候，空间效率会更好。
Tablespaces that have a lower sequentiality ratio also are better candidates for SSDs.
具有较低连续率的表空间也比较适合放在SSD上。
The seq column sometimes has little meaning (other than indicating the absence of sequentiality pertaining to some rows).
