We've used several Kingston SA400S3 SSDs on OpenBSD machines, including as boot drives, and not had many problems. Can you provide the output of the atactl identify command for this unit? One thing we have noticed is that large continuous writes to these SSDs often result in extremely slow performance for a while after ~500 Mb of writing, with the process stuck in a biowait state. One unit that had been in use for a couple of years got so bad that we had to secerase it, and which point it seemed to brick itself for about 24 hours before coming back to life and on the face of it working just fine ever since. Our Sandisk Ultra II and Corsair Force SSDs have never shown similar issues.
