Description

I am under the impression that SSDs connected to the compiter via a ASMedia AS2115 USB3 SATA adapter are unacceptably slow, although I need a scientific method to test this.

```
usb_msc_auto_quirk: UQ_MSC_NO_GETMAXLUN set for USB mass storage device ASMedia AS2115 (0x174c:0x1153)
ugen1.16: at usbus1
umass0 on uhub7
umass0: on usbus1
umass0: SCSI over Bulk-Only; quirks = 0x0100
umass0:0:0: Attached to scbus0
da0 at umass-sim0 bus 0 scbus0 target 0 lun 0
da0: Fixed Direct Access SPC-4 SCSI device
da0: Serial Number 00000000000000000000
da0: 40.000MB/s transfers
da0: 122104MB (250069680 512 byte sectors)
da0: quirks=0x2
```

Is there anything we can do to remove bottlenecks? I don't expect native SATA performance, but I expect better than what I am seeing.
