does anyone have any experience with this drive? i have the momentus xt which i love . but i just got as a gift , the intel x25-v and i would like to put it on my macbook pro and also throw another hard drive only for storage . is the momentus lp a good hdd ? or what do you guys think is the best ? buying a new hard drive (5400rpm ) or keep the momentus xt (7200rpm) just for storage ?
