P.S. I have a place to mount the SSD, but it would be a real pain to get it in the proper mounting bracket. I saw on a video that someone used double sided tape to tape the SSD to the case. Is that actually OK to do?
Agreed. I own a Samsung 830 and love it. The difference in speed is insignificant. The 830 also comes with a mounting bracket (thought some places offer two options, one dos not include a bracket but is a tad cheaper).
You can mount it however you want, but personally I would never use tape as a means to mount anything in my PC.
