OK. Thanks. But if I have a big volumes in TB size (10 TB volume) and writing/reading from the big volumes - will impact on performance like write and read speed? I surely see some impact on writing and read because - all chunks going to multiple OSD, where encryption requires, which may cause slow writes. Similarly for read also. Thanks Swami
