Centos7 HP GEN9 with H240 Smart Host Bus Adapter with single 512GB SSD Samsung 850 PRO as RAID0

Could you provide an iostat output to check disk io during the restore.

iostat -x 1 10

And also elaborate on “Launched in one thread works without a problem, recovery takes too long , by default 20 threads !”

Could you provide your service stanza configuration from aerospike.conf ( service-threads, transaction-queues , transaction-threads-per-queue) to confirm threads used.

A few recommendations:

  1. Make sure disk cache policy is set for each drive with Write Through (WT) and NO Read Ahead (NORA).

  2. Ensure that your Samsung 850 Pro is over-provisioned prior to using it with Aerospike.
