Hi,
I have a FreeNAS-11.1-U4 server, based on a SuperMicro 3U server, 8-core CPU, 128GB RAM, 2x SAS12 controller connected to a SAS12 backplane with 2 SAS-expanders.
I have 6x Kingston DC400 800GB SATA SSD's and 6x Seagate 2.4TB SAS 10K HDD's, both configured as striped mirrors.
Kingston SSD Volume performs 1-1.5 GB/s, which is fine, but Seagate SAS volume performs at 25MB/s, and that is simply too slow.
1 of the Seagate SAS drive can perform up to 270 MB/s alone, so I cannot understand...
Slow SAS drives Volume, SSD Volume fast
