It is time for me to change my hard drive. After going through the several reviews and tests (including the one of Tom's hardware), I found out that the Quantum and Ibm hard drives are the best ones on market right now with the Quantum one performing better in most of the tests (4 out of 5 I think) carried out. Their price is exactly the same and I could really use some help. The question is: Should I buy the new 40GB Fireball Plus AS Quantum or the half year old DeskStar 75 GXP IBM's 45,6GB???????????
