At the moment my prefered SSD manufacturers are Crucial and SanDisk due to the use of Marvel controllers which have been without bad media attention as far as I know, and renown for their reliability.
OCZ is coming back into the fold as an option for me because Toshiba have honoured OCZs warranty on their premium older products, from what we have heard here and a family member of mine has experience with them; their in house controller is meant to be pretty good but didn't get the attention it needed before they went under, Toshiba seem to be giving it all the attention it needs and their oversight should hopefully improve customer service which OCZ had trouble with before the take over.
I seem to have disliked Samsung for a long time now, not sure what it is about them as a company that I dislike so much but they get a wide berth when I am willing to spend money on technology. Biases can be weird I guess... This thread doesn't help me think any better of Samsung to be honest.
