Replacing the HDD with SSD and reinstalling Mountain Lion

Yay! 🙂

Now after successfully replacing replacing the HDD with SSD, what i need to do to get its optimum performace? (Like TRIM?)

That's out of my comfort zone. 😟 Dr. Smoke has some good performance, etc., stuff here: http://thexlab.com/faqs/faqs.html It may not have much on Mountain Lion, and I don't know offhand if he covers SSDs.

Otherwise, you might want to post that sort of thing either here or in the hardware forum: https://discussions.apple.com/community/notebooks/macbook

Thank you again 😀

Good to see you made it and happy to hear I provided some help.

As to TRIM, there's another thread dealing with installing an SSD, specifically an M500, where TRIM came up too. As you'll see, Crucial doesn't consider it necessary but doesn't seem to consider it damaging either. But digging deeper, the benefits of TRIM appear to be real both in terms of performance consistency and SSD longevity.

You don't need TRIM. You have garbage collection which is what newer SSDs come with. Besides, if you enable TRIM in OS X, you have to remember to do that each and every time you reinstall OS X or install future updates like today's released 10.8.4.

When I installed my SSD (from OWC), they told me there was absolutely no need for TRIM.

And if it used a SandForce controller, which most of theirs do, SandForce controllers don't play well with TRIM, and one of their earlier firmware versions didn't get along well with TRIM at all. The big advantage of TRIM appears to be reducing write amplification, and the method used has improved performance consistency as an additional benefit, which is likely why Apple does use it. I don't use TRIM on my OWC SSD either but that's because it's internally a RAID configuration, which TRIM doesn't support at all.😟

Enjoy your new hard drive??

🙂

I knew that 🙂 and my tongue in cheek answer was 'No, not really'....... (disclaimer: you have a different brand of SSD and I am basing my answer on my OWC drive)...

Haha! Certainly :) But I'm asking if there is anything I can (or need) to configure so that I 'truly' enjoy my SSD ;)

Enjoy it, it's faster, and if there is a tweak available you'll find it. Then it will be faster still.

Don't bother about (or believe) those 2 second boot claims, 5 to 10 seconds is very fast. And why boot?, close the lid and walk away, now that is almost instantaneous, and better for the machine.

In the interest of SSD longevity, is that necessarily a good idea? E.g., my rMBP has 16 GB of RAM. Every time it sleeps, a new sleepimage is written in the /private/var/vm directory. In my case, that's a 16 GB write each time. Since SSD boots are remarkably fast, shutting down and rebooting avoids that with little loss of time. It just takes an extra button push.

I do let mine sleeps 3 or so times per week, but will shut it down the rest of the time. Since a lot of glitches are fixed during the bootup process, I like doing that just as a preventive measure if you will - in addition to the fact that I was taught not to waste natural resources.

Stop worrying, unless you've entered a booting competition this is neither here nor there, enjoy your Mac.
