The fastest disk I/O on trimslice, based on my testing, is via iSCSI over the ethernet port. It can do gigE (125MByte/sec) where usb/sata on arm seems to be limited to 27 MByte/sec or so (37 MByte/sec on intel i7).
Are you really MB/s rather than IOPS bound?
37 MBytes/sec is close to the USB480 limit, considering overhead, I think. I don't know why the arm devices seem to be limited to 27 MBytes/sec on USB disks, but those were the numbers I saw.
