Summary: I bought two of these six months ago, one for me and one for a family member and we are both very satisfied with this SSD. This is my first SSD and with windows installed on it my pc boots in seconds!
Summary: I bought two of these drives and put them in RAID 0 to replace a failing mechanical hard drive. I noticed a speed increase since day one and will never go back to using a mechanical hard drive as a boot drive. The only thing I don't like is that the finish holds on to fingerprints very well, but that's on the inside of the computer anyway so it's not noticeable.
Summary: high price used to stop me buying intel ssd. Now they are pretty much same as other competitor. this 330 240gb was an amazing deal for me, and mine is retail, comes with mounting kit and nice 'speed demon' sticker. it's very reliable, I run trim regularly, and diag time by time. 4 month, so far so good. 330 is slower than 520, also slower than crucial M4. But the gap only reflects on benchmark score. I own 330, 520, and m4, I can't feel much diff for common daily use.
