Hi. I am considering upgrading my Lenovo Thinkpad R61 . It currently has 1Gig RAM and has SATA 7200@ 100GB HardDrive. I want to replace it with max of 4 GB and replace the Harddrive with about 500GB @7200. I use UBUNTU /Xp on a partition. The laptop has an Intel Core2 Duo, T8300 @2.40GHz. I looked up Seagate Momentus XT 750 GB 7200RPM SATA 6Gb/s 32 MB Cache 2.5 Inch Solid State Hybrid Drive ST750LX003 but quite a few reviewers said that after a few months it starts to give problems. Any and all suggestion would be appreciated. Also, pls. suggest which brands of the memory as well as harddrive ,you suggest. Also, for reference, the HardDrive i have right now,the model no. is : ST9100821AS Not sure if there are other specs that i forgot to mention. Thanks a ton.
