HDD Speed details

[rizvii]

I have two Sata HDD. one is of 160 GB and the other is of 80 GB. I installed windows xp on 160 GB and then I installed it on 80 GB. I noticed that the speed of 80 GB is more than that of 160 GB. Both HDD are MAXTOR. I want to know why the speed is different. Should i assume that smaller HDD are faster than bigger one.


Thanks

Not necessarily. Unless the drives are exactly the same series and model, they could have different specifications. A newer 500GB drive may outperform an older 80GB drive. But most times, the bigger the drive, the slower it can be. More heads, more platters and longer seek times. But hard drive controllers have improved along with HDD firmware and engineering and some large drives perform very well.

I have a WD 500GB SATA HDD that runs AHCI (Advanced Host Controller Interface) controller software on a Vista PC and it does read/writes at 80MB/s, which is faster than many of my older, smaller drives.

You would need to go to the hard drive manufacturer's site and find the specifications for both drives and you may see quite a listed performance difference between the two.

You can try the drive benchmarking program linked in this post to give you some idea of your drives performance. https://forum.videohelp.com/topic366366.html
