Speed slow after installing new HDD

[jianwei87]

I just purchase WD 500GB 8MB 54000RPM SATA HDD, after i installing new HDD and Snow Leopard in my new HDD i feel my MBP speed obviously slower then my pervious HDD. Why?

Try resetting PRAM and see.

Except restting PRAM what can i do?

I trying to reformat my Mac OS X seem it doesn't affect the delay copy/read speed.

I installed a 640gb 5400rpm HD. My computer feels slightly less responsive too. Just the drives aren't as fast, I guess. I get improved sequential read/writes, but random writes suffer, so I lost some performance, especially during multitasking.

Try a different brand drive or get a 7200 rpm if it really bothers you.

do you think this is hardware problem or firmware?

I have no idea. I'd guess that it's just the hard drive isn't as efficient once in the machine.

If you cloned the drive, make sure to repair permissions. If its a new install, doesn't Spotlight take a while to index things for searches? Otherwise, go compare the benchmarks for your old and new drives at www.harddrivebenchmark.net.

The benchmark that i get is Western Digital 446 and the original MacBook hard drive get 303. This benchmark test is showing that the Western Digital are more efficiency but performance are slower down when using in Mac.
