for this reason, you want a controller with battery backed write cache. in practice this means a RAID controller, even if you don't use the RAID functionality. of course you can buy SSDs with capacitors, too, but I think that will be more expensive, and it will restrict your choice of model severely. (BTW, thank you for testing forceful removal of power. the result is as expected, but it's good to see that theory and practice match.) -- Kjetil T.
