[Smartmontools-database] Incorrect data for Seagate Backup Plus Hub 6 TB

Dear Sirs,
The information at https://www.smartmontools.org/wiki/Supported_USB-Devices
regarding Seagate Backup Plus Hub 6 TB seems to be a bit incorrect. The
correct way to access SMART data on this device is to disable all
usb_storage quirks (echo "0bc2:ab38:" >
/sys/module/usb_storage/parameters/quirks and reconnect the USB cable) and
then use smartctl -d sat /path/to/device. With the default kernel quirks
for Seagate enclosures ("t") the way to access the device is smartctl -d
sat,auto /path/to/device but then the SMART output will be partial only and
it seems like SMART is supported but disabled. The hdparm -I and hdparm -i
does also works once all quirks have been disabled.
This enclosure has two USB devices (one USB hub and one USB-SATA bridge. As
far as I know the USB-SATA bridge is connected to the hub and the same hub
also has connection to 2 external USB 3 ports in the front of the enclosure
for additional end user devices).
0bc2:ab38 is the USB-SATA bridge
0bc2:ab45 is the HUB
I haven't dismantled my device but accoding to PCB images and some Youtube
videos it looks like this enclosure contains Genesys Logic GL 3520 (4 port
USB hub controller) and ASMedia ASM1153 USB-SATA bridge.
I've transferred around 4 TB of data (both read and write) and it seems
that UAS does work correctly with this device without any usb_storage
quirks both over USB2 and USB3 ports.
The actual real world performance with full UAS features seems to hover
around 80-150 MB/s for read and 0-160 MB/s for writing when connected to
USB 3 port. The SMR behavior is really bad and the write performance goes
through the floor every now and then if you keep writing to the device a
lot (write IOPS goes from around 120 to 0). Long time average for writing
is around 30 MB/s if you keep pushing bytes even when write performance
drops. The drive seems to have around 10-20 GB internal non-SMR
cache/buffer where performance is good but once you go over that limit, the
write bandwidth goes all over the place. The drive seems to do internal
cleanup of the cache/buffer area if both power and USB cable are powered. I
have seen extra activity for around 20-30 minutes after stopping writing
lots of data or after connecting the drive that has not been completed the
cleanup before power has been disconnected. Connecting only the power
source cable is not enough to get the drive to initiate the cleanup but in
addition connecting USB cable to power only USB port is enough to trigger
the cleanup cycle as long as both cables are connected. When USB cable is
disconnected the drive will go to sleep even if internal cleanup is waiting.
