Good hard drive performance?

Posted on 2012-08-21

I don't have a very good feel for what's considered "good", in a hard drive benchmark test.

I use HD Tune Pro to test the hard drives, and it comes up with several different metrics. I've reviewed the manual and I think I understand what they all mean, and understand concepts like how the outside part of the hard disk platter gets faster speeds than the inside, how SSDs require 4kb alignment, and the concept of hard disk "thrashing" and why SSDs have faster access times than regular hard disks.

But I don't know what actual results would be considered "fast" and what would be considered "slow" these days.

Especially the statistics on operations per second (IOPS),  access times (ms), and low-level read/write and file-based read/write with different block sizes (megabytes/sec)... what kind of results are considered good?

Any insights?

    In case anyone is interested, here's the results of running all the HD Tune tests against three of my hard drives: A top of the line 120GB Intel 510 series SSD, a mid-range 250GB SATA drive, and a relatively old 160GB IDE disk.
