Hi all..

I have 8 ssd's (Toshiba Trion OCZ 150 480gb) hooked up to an 9205-8e with 2 SFF 8088 to 4 X SATA cables.

It's sitting in an HP Z800 (96gm ram) running proxmox (latest v4.xx). The lsi is placed in an 8x pcie 2.0 port

I have made two raid0 arrays (four ssd's in each) with mdadm and i don't get the speed between them that i expected..
I can't get over 700mb/s transferring large (+8gb) files between the arrays..

Is that the expected speed with this kind of setup?

Having an all-flash storage array I would rather go with RAID5 (unless you literally need that much IOps).

Among the worst SSD possible, I know I have a couple older models I got to play around with.

The OCZ Trion 150 SSD Review

They suck at pretty much everything, even reading data is BAD on those SSD.

#'s are probably what you're gonna get out of those.
