Memory and HDD for my X61

I intend to upgrade my memory from 1 to 4GB, so can anyone tell me which memory brand is the best. I mean which one is the most reliable. The same for HDD.

thank you

 

Most of the memory comes with a lifetime warranty but right now a good deal is from Fry's, 60 bucks for 4 gigs after mail in rebate.

HDD is usually a hit or a miss but Hitachi, Seagate are brands that I hear are liked most in the notebook area.

 

Thank you very much for the info.

 

My personal machines always get Crucial RAM and Hitachi hard drives. I've used Cricial for years and have never had a DOA chip or one that has failed during the life of the machine. Hitachi drives have been used in Thinkpads for years as well. Other than some odd behavior in my old T43 (which had a SATA/PATA bridge chip, used PATA drives, and required IBM firmware to POST w/o errors/warnings) they have been trouble free for me as well.

Based on feedback in the forums, Crucial, Mushkin, Kingston, Hynix, and some others have been used with success. Mine shipped with Hynix.
