Использовал вот этот замечательный трим-тест, который выдал такое:
# ./test_trim.sh test1 6 /dev/sdc
1+0 записей считано

 скопировано 6291456 байт (6,3 MB), 0,714876 c, 8,8 MB/c
test1:
 filesystem blocksize 4096, begins at LBA 110639104; assuming 512 byte sectors.
 byte_offset  begin_LBA    end_LBA    sectors
           0  110958592  110966783       8192
     4194304  111040512  111044607       4096
/dev/sdc:
reading sector 111040512: succeeded
ffff ffff ffff ffff ffff ffff ffff ffff
...
потом такое:
This is a sector of the file. It should have been successfully read
and show a bunch of random data.
Press any key to continue... 
File deleted. Sleeping for 120 seconds before re-reading the sector.
If TRIM is working, you should see all 0s now.
/dev/sdc:
reading sector 111040512: succeeded
ffff ffff ffff ffff ffff ffff ffff ffff
...
If the sector isn't filled with 0s, something is wrong with your
configuration. Try googling for "TRIM SSD Linux".
