For fast ZFS pool u need lot of ram and fast SSD for ZIL log. In other case RAID5 will be much faster. Configuration depends of yours needs. U need to choose if you want to store/copy lot of small files or big like a video files. If you will store big files and write it and read sequentially I recommend to create RAID5 with large stripes like 256K. Create a FS with big blocks. Also I thing its better to use partition on disks rather than using whole RAW disk space because you can set proper alignment. Check if yours disks have 4K sectors or 512B. For me that configuration is doing 40-50MB/sec with reads and ~35MB/sec writes using Samba.
