I am about to buy a Macbook Pro, specific model unknown yet.

I am very interested in upgrading to an SSD, as I/O latency is extremely important for my work. However, I have no experience with Macbook Pro performance.

Is it worth it? Will the performance be significantly better? What about durability? Any noticeable effect on battery performance?

Do note that OSX doesn't have TRIM support for SSDs yet, although the 10.6.4 update has given some indication that it might come in the near future. – Om Nom Nom Jul 17 '10 at 18:25
@Om Nom Nom For that reason, AnandTech recommend SandForce SSDs for Mac users – sblair Jul 28 '10 at 12:48

I installed an Intel X25M 80 GB SSD on my MBP about 4 months ago.

Unscientifically, I can say that my boot times went from 50 seconds to about 10, including starting my browser, terminal, mail client, and IDE. No application takes longer that 3 seconds to load.

I would guess that my battery life increased about an hour per charge on average.

I haven't had it long enough to determine if performance degrades, though. It has stayed consistent so far.

Again, nothing scientific, but I love my SSD.

Cool! How did you install the SSD? The X25 is not officially supported by Apple. Didn't this void your warranty? – Yuval A Jul 18 '10 at 11:41
I used the Lifehacker guide at… -- I think if I ever have a problem I'll just swap the old HDD and no one will know the difference ;) – Eric Wendelin Jul 19 '10 at 1:38

I installed a 240 GB OCZ Agility 2 - A SandForce 1200 Controller Drive - a month ago.

Although the program I used (Carbon Copy Cloner) failed to write to the drive successfully, causing some frustration, I eventually used Disk Utility to image.

After that no problems. Don't worry about no TRIM support in OS X, the drive is fine. Do:

  1. turn "noatime" on
  2. never use any defragmenting software
  3. turn off "safe sleep"

It's taken my drive performance from a stock 5400 rpm HDD from 62 MB/sec to ~270 MB/sec.

Access time for everything is better. Virtual machines run way smoother. Applications launch within 3 seconds.

The drives may not last at this level more than a couple years but I'm stoked so far. You can't go back to platter drives and moving parts after this.
