I have a 128 GB Samsung 830 series SSD and love it. They are getting hard to find now because they replaced them with the 840 series. There are two versions of the 840 SSDs. Normal and Pro. I think the Pro is closest to the 830 series, but have not dug too deep into it. I also have three 1 TB Samsung HDDs that are working great (Pre Seagate buy out).
