Summary: I have many HDDs throughout the years, IBM, WD, Maxtor, Seagate, Hitachi, Toshiba. Generally of all the brands and models I have owned over the years, I have only had issues with Seagate. That is the only one I will definitely avoid currently.
Summary: Four of five ordered new perform okay after several months, one could not be formatted. The 8mb cache makes them distinctly slower than the 16mb cache they replaced, if speed is a consideration.
Summary: Installed in my laptop Vostro 3300(dell). My first 4k sector alignment HD, not a bad indeed.
Pros: Half a Terabyte, I can run Win7 plus 3 other of my favorite linux distros and still have ample room for storage. 4k sector manual partition went without a hitch. No noticeable speed loss compared to the WD Scorpio Black HD. Runs a tad cooler than Scorpio. Very economically priced.
Summary: Arrived on time, in its packaging, and my PS3 accepted it perfectly. So for all of you who zipped to this product after reading the PS3 harddrive replacement instructions, this is what you are looking for. Update: This hard drive is still working perfectly and I bought it over two years ago.
