Hello
I currently have 4 128Gb Samsung 850 pro's and 4 seagate 1Tb in a tiered mirror storage space. The 4 seagate drives are housed in an Rackable SE3016 connected to a IBM 1015 in IT mode. The 4 samsungs are direct connected to the 1015.
My issue is that I'm not getting even remotely close to the speeds that I'm expecting from a tiered storage space with 2 columns.

Everything shows that the drives and the brand new ssd's are in good shape, and I created the space with the default tiered arrangements (1gb write cache, 2 column, mirrored)
I'm kinda stumped at the moment.
Thanks
