7200rpm: is it worth it?

news Add comments

When I bought the macbook I immediately replaced the stock 160GB, 5400rpm hard disk with the faster 7200rpm in production nowadays: her majesty Hitachi 7k200 (HTS722020K9SA00).

Being this HDD quite expensive (due to the shortage in production) how much it improves seek/read time? I can confirm that power consumption and noise are the same as the stock unit, and that is wise to buy the 100 or 200GB models with an higher storage density per disk face in comparisono of the 160 GB unit.

Here there are some benchmark between a 200GB 7200rpm Hitachi 7k200 running a 3,1 macbook (2.2GHz Merom based, 4GB ram) and the stock 160GB 5400rpm Fujitsu on a 4,1 macbook (2.4GHz Penryn, 4GB ram). So sorry but no HFS+ bench, I can’t find any decent benchmark app for OS X: Xbench is extremely old, and Geekbench 64 told me absolutely random crap marks on the new Penryn, reporting a numerical result more or less the half in comparison of the “old” Merom one!?!

UPDATE:
Crappy vid: Leopard boot time (RIGHT: 7200rpm, LEFT: 5400rpm).
Consider both have a 5 s timeout due to rEFIt.
