Doesn't compare to other top-notch ssd drives (e.g. ocz vertex), but a good upgrade for using windows on the Acer Aspire One aoa 110w 8GB linux edition. The system is not blazing fast responsive with windows on, comparing to the linux OS but one can use all the windows programs. The fit is perfect, it screws directly in the place of the old ssd drive. Attention when removing the zif cable from the old drive-it is glued on it, but it can be reused easily on the new ssd drive. After the upgrade if a blank screen appears a bios update is required.
