Just as well. They had some of the least competitive drives when you compared pricing and specs to others. I wouldn't have bought any WD SSDs. But then again I wouldn't buy SanDisk either. Highest failure rates of any SSDs we have purchased. They were better before the WD acquisition.
I'm actually a bit surprised, I mean SSD's are the future right? And yes I've read many bad things about SanDisk, but I assumed WD was pretty good, both for external and internal drives. So this is probably a marketing blunder.
