I used a Samsung 840 120GB SSD on an Elbox FastATA Zorro MkIV with Mediator, Radeon 9200, Spider, CyberStorm 060/50 MKII with around 32O MB total fastram.
I also had a CF-card and a normal 2,3" mechanical harddrive connected, but theSSD was set as boot drive and with the highest bootpri.
What i noticed though, was that if i were to remove the other "drives" and let the SSD be connected alone, it sometimes wouldn't boot.
When that's said though, i had a rather complex configuration with Remul, softkicking, updated and maybe not so stable and official libs, devs, handlers, etc...
Make sure you have the correct scsi.device and 040/060 libraries, take one step at a time, and you should be fine. :-)
