+ 5 Votes One thing that worries me regarding these 2 links... SmartAceW0LF 2 years ago is that you are purchasing these drives with the HP label on them. This "seems" to indicate that you are buying OEM drives. OEM drives from either of the 2 manufacturers carry an entirely different warranty. Generally, OEM drives must be replaced through the PC mfgrs warranty. Thus, the effective warranty is only as long as the PC is covered under warranty. It has been my experience that when purchasing replacement drives, its a good idea to steer clear of OEM drives and purchase them from a reseller otherwise. My recommendation would be to purchase one of these 2www.newegg*dot*com/Product/Product.aspx?Item=N82E16822148591 orhttp://www.newegg.*dot*com/Product/Product.aspx?Item=N82E16822136856Replace *dot* with .Both of these drives are 7200 rpm drives which equates to significant performance improvement. While I havent used any of the hybrid drives made by seagate, they do get good reviews. Of the 2 listed, The seagate is 3 years warranty and the WD is 5 years warranty. Both are less in cost than the ones you posted and the reseller is second to none in my opinion with regards to price and standing behind the products they sell.
