SSD drive comparison help

Not taking a brand name into consideration, or the capacity of the drive, I’m trying to decide which of the following two perform faster, and are more reliable. A Intel 520 SATA3 SSD , or a Samsung PM830 mSATA SSD . I am unfamiliar with mSATA SSD drives, and there is a lack of info online. One link I found http://thessdreview.com/our-reviews/samsung-pm830-sata-3-256gb-msata-ssd-review-ultrabooks-to-gain-capacity-and-sata-3-speed/#disqus_thread claims the Samsung PM830 mSATA is a SATA3 drive, but I’ve had others tell me it’s not? I have both but will be returning one, and I’m trying to make a choice between the two, not taking the brand name, capacity, or any other SSD brands or drives into consideration.
