If you are using SSDs, it is not necessary to use RAID with Cassandra. For this reason, there is no recommended stripe size.

But if you weren't aware, the recommended read-ahead is 4KB for SSDs and 64KB for HDDs.

For more information, see Recommended Production Settings. Cheers!

如果使用的是SSDs,则无需将RAID与Cassandra一起使用。 因此,没有建议的条带大小。

但是,如果您不知道,建议的read-ahead对于SSDs来说是4KB,对于HDDs是64KB。

有关更多信息,请参见Recommended Production Settings
