Yes it will work. Although, be careful. The increased memory speed makes hard drive access alot faster. This, with the high centrifugal speed of the drive will make all the data drift to the outside edge of the platters, corrupting data. Placing a penny on the laptop when in use will prevent this, due to magnetic shielding, and also do not operate your laptop on a flat surface. Keep it at a slight angle, and don't run it for 10 hours or more continous.
Hope this helps.
