M1330, 7200 RPM or 5400 RPM, owners PLEASE

Can you pleasee post the model numbers of your hard disk and if it's a 5400 RPM or 7200 RPM.

It's available by clicking Start (Orb) then clicking on computer. When that opens, right click on your C drive, go to properties, then click the hardware tab. The model number is the thing that has ATA Device next to it, it's goin to be the one with the long model number.

I want to look up the power specifications to see the battery life hit.

THANK YOU SOOO MUCH IN ADVANCE!!! (and sorry if my directions for getting the model number are incorrect, i'm using a sony right now and not a dell)

 

ST9160821AS 160GB 5400rpm on an m1330 recieved 2 weeks ago

 

250gb 5400rpm .. WDC WD2500BEVS-75UST

 

thank you guys very much!!! 160 GB 7200 RPM is all i need and i'll post the research

 

hey own3d just wondering, does your hard drive constantly make a loud clicking noise?

I also have a WDC WD2500BEVS-J5UST0 250 GB 5400 rpm

 

Fujitsu MHW2160BJ FF 160GB 7200RPM

 

ST9160823ASG 7200 rpm 160gb seagate

 

ST9200420ASG = Seagate 200gb 7200rpm w/ free fall sensor

 

my t9500 hums and vibrates... not uncomfortable but annoying..
I'm going to replace it.

 

My 250GB 5400 is a Samsung HM250II.

I get a loud click after is comes out of standby. When I am using the laptop it is quite.

Fujitsu MHY2169BH 160gb 7200rpm

No vibration or noise.

 

If everyone can post whether their HD causes their laptop to vibrate or not, that would be greatly appreciated.

 

No vibration here with a Sammy 250GB 5400.

7200 over 5400 gives roughly 20-30% increase in performance for read/write. This means faster boot. Unfortunately, it runs hotter and burns your battery faster. I'm sticking with 7200 because I love my load speed for everything.

 

Those read/write speed increases are only over an equal size 5400rpm hard drive. The larger the hard drive the higher the density and therefore the higher the speeds, so for example a 320GB 5400rpm has similar read/write times to a 200GB 7200rpm. However what 7200rpm drives always have over 5400rpm are slightly faster access times and of course 160GB 7200rpm vs 160GB 5400rpm the 7200rpm will be much faster, cause they are the same size.

darksiege the Seagate Momentus 160GB 5400rpm doesn't make the laptop vibrate, however it does make a loud clicking noise very often.

 

If you have your disk set up correctly, even on both, you will see a huge difference...my wife had a 5400rpm in her's for a while and I finally swapped it out. Boot time dropped drastically and everything loads much, much faster.

Vista runs up to 20GB in size, 10% of a 200GB 7200rpm disk, or 5% of a 400GB RPM disk, to make math simple. The 10% of the 200GB is still pretty much maxed out at 55 MB/s.

5400rpm have about 45MB/s from the start and drop from there. 7200rpm does not reach that until around 60-70% into the disk. For a 200GB, at least 120GB is faster that the fastest part of a 5400rpm. For a 160GB roughly 100GB is faster. That's being conservative on these numbers, giving nearly a 18% performance difference between the two when reality is like I said, around 25% difference.

The density merely gives a greater amount of data faster performance, but a 5400rpm will always perform much worse unless benching against a 100GB 7200 where 70GB of video files are stored on the outer edge, then the OS is in the center. In that case, a load of the OS will take longer than the 5400. If you want to give it a try, get ultimatedefrag and do just that.

Also, dimensions are the same for most 2.5" disks. The benches, which is what I spoke of above are a little different than the math. The math supports you much more:
%of disk inches inches data 200GB
displacement 7200 5400
2.5 15.7 113040 84780
2 12.56 90432 67824
0.925 1.8 11.618 83649.6 62737.2 15
1.5 9.42 67824 50868
1 6.28 45216 33912
0.5 3.14 22608 16956

Using good old algebra, only 15 GB would be faster than the 5400, and then the density of the 5400 would catch up. Unfortunately, the reality and the hardware works a bit slower on a 5400.

 

Thank you, as I just don't think a vibration/ lowgrade hum is
okay.. I don't have it on my 1210.
