Two quick questions

I was wondering what's the difference/which is better between the intel core2 duo's: p9500 2.53 ghz and the t9400 2.53 ghz?

Also why does everyone keep saying that the 320gb 5200rpm's are the same as the 7200's so long as it's sata and series 300???
---Don't just answer "because they are" I want some decent explanation

Thanks

I think you were a little misdirected. The 320 GB 5400 RPM drives are equivalent in performance to the 200 GB 7200 RPM drives because of the larger drive's higher data density.

The data's closer together, so it doesn't need to spin as fast to get sequential read speeds, or something. Now the 320 GB 7200 RPM would be one fast drive.

 

Thanks, and the processors???

 

Ah, the P9500 only runs at 25 watts. It's more power efficient. Should run cooler and consume less energy.

 

The P9500 has a lower TDP than T9500 25w vs 35w this means it produces less heat. Less heat means more efficient with power use means less used.

The 320GB @5400 being the same as @7200 has to do with smaller or more specifically 7200's with less areal density. A slower disk speed can be compensated for by having more data in a given area. This is usually most noticeable in sustained reads and writes (avg) vs Random access. So platter density is an important factor in HDD performance just as rotational speed. Same density faster rotational will be faster.

Hope this helps. If not then "because they are".

Edit: I type slow and provided link and quote. Oh well?

 

Alright well thanks guys, I kinda get it---- it would be the same odds of finding many needles in a large hay stack at a slower search rate, as it would to look for a couple of needles in a smaller hay stack searching quickly. w00t well I'm off to the bank to fund my purchase. 320gb 5400 it is. As for the processors i don't think it's worth the extra $40.

 

You are making a good decision so do not want to stop you. Better analogy for HDD. DATA. You have two runners who will pick up biscuits that are placed on a 100yds track? Lane one has a biscuit every 10yds? Lane two every 5yds? The race is started the runner in lane one finishes in ten seconds and has 10 biscuits? At that same moment in time on lane two the runner is at 50yds (half speed) but they would have ten biscuits? Biscuits are DATA? That is the point.

You kind of changed the wrong variable? Or even more just not good example? Notice my faster guy travels further (larger hey stack) so yours is well kind of backward?

 

I want the lane which has two cookies per every five yards, me hungry

good analogy their PP, higher density drives really do increase drive performance as a high density 5400rpm, drive can compete very well with the first and secong generation 7200rpm drives.

The 320gb 5400rpm drives are the best bang for the buck drives, they are really fast and offer a very high capacity for a notebook.
