They are outright lying on their website. They tell us that their SSD requires less power than regular HDDs and this is completely not true. After putting their 512 GB model into my MBP, I lost ~10-15% battery power. Kingston has been unhelpful and just tells me that "the SSD consumes less power than a regular harddisk and this has been confirmed by our technicians". Hell I had even a 7.2k drive in my MBP before which consumes MORE than a regular HDD and here I am losing 10-15% of battery life to their SSD. They are just lying through their teeth and they should not be trusted. It really really sucks. I've been at 10 emails so far but only robots reply as it seems. I just hope they would pull a firmware update out of their sleeves but I think it's very unlikely. Given the price of this piece of equipment I'm all but happy. Tom PS: I know about the Tom's Hardware article that says that you will lose battery power when switching to SSD but this was two years ago - I was hoping times changed but it looks like they haven't.
