Hello,

I had a HP Pavillion ZV 6000 (2004 laptop). It came with 512 MB ram upgradable to 2GB which I did a couple of years back. The only bottleneck was HDD. It was ATA-100, 4200 rpm with no cache information mentioned.

I got a external passport size 500 GB Segate 5400 rpm, 8mb cache, and that performed faster than my internal hdd even though it was limited thru a USB

So I decided to upgrade my internal hdd to a ATA-100, 5400 rpm, Western Digital, 8MB of cache. The difference between 4200 rpm and 5400 was 29% but the actual difference when I benchmark it with the exact same clone was 35%. So my question is, will it make sense for me to try 7200 rpm. Will it even give me a 35% performance increase again?

The only issue is with ATA-100, 7200 rpm is the hdd storage capacity.

Please provide your inputs and thoughts.
