I have tested the following different SSDs

ATA      INTEL SSDSC2BX01 1490.42 GiB   
HGST     HUSMH8010BSS204    93.16 GiB
HGST     HUSMR1619ASS204  1788.50 GiB   
HGST     HUSMR3240ASS204   372.61 GiB   
SAMSUNG  MZILS3T8HCJM/003 3576.98 GiB   
TOSHIBA  PX04SRB192       1788.50 GiB
WDC      WUSTR6440ASS204   372.61 GiB

For testing, I created a zpool, or used the existing zpool, on the device, wrote a bunch of files into the dataset, then deleted most of those. I ran a trim and verified that 'zpool status' showed the device was trimming for some period of time. After the trim was complete, I scrubbed the zpool to verify there were no errors, and then exported/imported the zpool to confirm there were no problems. For the system's main pool (rpool or zones), I could not export the live pool so I rebooted to confirm things were ok.

There is no way we can test every SSD out there, but our code is consistent with the upstream philosophy from OpenZFS. They do not have a blacklist either, and recommend that people simply buy good quality SSDs if they want to use trim.
