Based on the review on Notebookcheck.net it seems that the X70 already has a 256GB SSD and a spare drive bay. So none of the replies so far make any sense...
That's only because none of the rest of us bothered to read the specs on the X70 (over-achiever). Given this new info, I don't think the additional cost of the Momentus XT is really necessary for data storage (it generally matches performance of 7200rpm drives
). For a primary system drive, sure, but not here.
If you've already got a SSD in there, check prices and get a 5400 rpm hdd. In general
, 5400 rpm hdds will: be quieter than 7200rpm models, use less power than 7200 rpm models, extend into higher capacity points, and should cost less than 7200 rpm models.
