Anyone looking for a low-power, and quiet hard drive, which I can the Hitachi Travelstar recommend. I bought the hard drive because I have had very good experiences in my two Dell laptops (no failure within 6 years). She has a small Bauhöheund thus fits as an additional data storage in CD trays for many notebooks. My experience: it is quiet, turn off when not in use, required course in a moment access start-up time until it works. For speed of reads and writes, I can not provide tests. However, for it has always been fast enough.
