hdparm's report mostly comes directly from the drive within the
enclosure. So all it says is that the drive within the enclosure
understands TRIM, but in many cases, the USB<->SATA adapter used in the
enclosure to talk to the disk only understands a subset of the SATA
commands.
You might ask the USB driver people if Linux's usb_storage
driver supports TRIM, if not, then there's a chance that the USB<->SATA
adapter still supports it, but I wouldn't hold my breath.

I highly doubt that TRIM would help. IOW, it's just a gut feeling you
have, but I strongly doubt you have concrete data that can show it might
be related to the presence/absence of TRIM-support.
