Pros: Crazy fast. Win 7, HDD experience index hit 7.1 after installing this drive. It runs cool. No noise. The programs open up much faster (multiples faster). Media Center acting much more fluid where it was stuttering before. I use this as my primary and only drive in my HTPC, and use external USB drive for data files in another room in order to maximize the silence factor. The future is clearly in SSDs.

Cons: I can not think of any.

Overall Review: Though I am an avid purchaser from Neweg, this is the first time I am writing a review as this ssd far surpassed my expectations.

Pros: Vista upgrade worked perfectly fine. I did submit the upgrade on Dec 27. Checked the status on 1/4 and it was confirmed. Not sure what is going on with other reviewers and why they can't make it work. Also Microsoft doesn't seem to be the correspondant in this process, it is ModusLink.

Cons: It is true that you can not get VISTA 64bit. It is 32bit home premium.

Overall Review: Do not plan to use XP. Just get it for VISTA evaluation version and eventually official VISTA.
