I recently upgraded the hard drive in my laptop (a Western Digital Blue, 640GB) to an SSD (OCZ Vertex 3, 240GB). I’d heard how much an SSD improves performance, and I can now definitely vouch for this; the upgrade has been a substantial boost for my aging mid-2009 MacBook Pro (Intel Core 2 Duo 3.06GHz, 8 GB RAM).

During the course of the upgrade, I did a couple before and after benchmarks.

Boot Times

First, I took some very informal measurements of boot time. I routinely boot into Windows using Boot Camp for work, so I have boot times for both Windows 7 and OS X Lion.

Windows 7

  • From boot menu to desktop:
    • Before: 1:15
    • After: 0:29
  • To launch Firefox
    • Before: 2:13
    • After: 0:40

OS X Lion

  • From boot menu to desktop
    • Before: 1:12
    • After: 0:17 (17 seconds!!!)
  • To launching iTunes
    • Before: 1:44
    • After: 0:29


I also took before and after measurements using CrystalDiskMark (a disk benchmarking utility for Windows).

Windows Experience Index

Lastly, here are the results from the Windows Experience Index utility on Windows 7.
