You can consider to use an Fast RAID card in IT mode and move the parity disk to this RAID card.
The idea is to split the traffic of parity and data disk to difference interface card.
(don't use those cheap and slow raid card like silicon image with PCIe x1 interfaceonly )
You can get a LSI 9240-8i (PCIe x4) in Taobao at about HK$6XX.
In my unRAID with 20 disk, I use 2 x 9240-8i + on-board SATA, the write with parity is about 80-90MB/s (MB is A885GM-A2 with dual core AMD CPU and 8GB RAM, quite Old but good for unRAID)
師兄唔好意思, 再睇當年 post http://www.hkepc.com/forum/redir ... 00&pid=27741836, Cache drive 一途似乎走唔甩
For Samba performance,
with SSD as cache drive I can easily get about 100MB/s write speed.
with HDD as cache drive, I can got about 60MB/s
without cache drive, I can get about 40MB/s
