Hi Stefan, I can only tell you that I had success with ASM1051 on the drive side (SilverStone Treasure TS04) against both NEC uPD720200 (rev. 3) controller and TI controller on the computer side. But ASM1051 does not propagate S.M.A.R.T. values back from the drive. Once I had a "bad firmware" in ASM2105 in SilverStone Treasure TS04B. That one I returned. I am happy with 4 pcs of "Manhattan Superspeed USB to SATA adapter" giving me each 150MB/s, working with 2.7TiB Seagate SV35 and Barracuda drives despite the fact the retail box claims the adapter support 48-bit addressing up to 2TB drives only. gdisk shows the drives report 512B sectors while should be physically 4kB sector drives. I am handling files of up to 250GB and shuffling data between 5 such drives. When things work on my laptop through one 2-port XHCI TexasInstruments-based controller, 1 eSATA port of SandyBridge and 2-port XHCI NEC-based express card I can read/write between all the drives (including writes to /dev/null) to total 2.5Gbps as shown by vmstat. From each single SATAIII drive I can get stably 140-150MBps with 5 drives I could not saturate the system throughput (well, just reads and writes to /dev/null as I said). A chase for working USB3 to SATA converters might take you to http://forums.whirlpool.net.au/archive/1558885 and from there to https://docs.google.com/spreadsheet/ccc?key=0AqniL4H-VGJSdEJPZTNjbFlEWlFEbU5adnFYRFRxeFE I have added some items to the table and also am attaching my old benchmarks. Maybe check if your express card works quickly enough? Maybe play with tehse kernel command line pci=option,option2,... parameters (from kernel-parameters.txt file): pcie_bus_tune_off Disable PCIe MPS (Max Payload Size) tuning and use the BIOS-configured MPS defaults. pcie_bus_safe Set every device's MPS to the largest value supported by all devices below the root complex. pcie_bus_perf Set device MPS to the largest allowable MPS based on its parent bus. Also set MRRS (Max Read Request Size) to the largest supported value (no larger than the MPS that the device or bus can support) for best performance. pcie_bus_peer2peer Set every device's MPS to 128B, which every device is guaranteed to support. This configuration allows peer-to-peer DMA between any pair of devices, possibly at the cost of reduced performance. This also guarantees that hot-added devices will work.
