Make sure the cables and power supply are ok.  Try the drive in another machine
that has a different controller to see if there is an incompatibility between
the drive and the controller.

You could make a btrfs file system on the whole device: that should say that
a trim operation is performed for the whole device.  Maybe that helps.

If the errors persist, replace the drive.  I´d use Intel SSDs because they
seam to have the least problems with broken firmwares.  Do not use SSDs with
hardware RAID controllers unless the SSDs were designed for this application.
