Upgrade Crucial C300 firmware on a MacBook Pro

I just got a Crucial C300 SSD to plug in my Mac. And it came in revision 02 ; but the latest bug free firmware is revision 07.

To upgrade, just go to the Crucial website and get the “C300_FW0006.zip” archive. Unzip and burn the ISO file. Reboot, use ‘alt’ to drop to the boot selector and select the CD drive ; it appears as “Windows”. Let the process find your drive and upgrade the firmware to 06. When done, reboot.

Now, get the “C300_FW0007.zip” archive and replay the previous scenario.
After a few seconds, the SSD has the latest firware installed:

So easy! And so nice it works on the Mac!

Crucial RealSSD C300 has TRIM on Mac OS X

I had the opportunity to get a Crucial RealSSD C300 256GB at a really decent price. According to its specs, it features TRIM. This should make a perfect disk for my MacBook Pro 13″.

Indeed, after a clean OS X Lion installation and the use of the TRIM Enabler utility, I have TRIM enabled of the cat:

Model Name: MacBook Pro Model Identifier: MacBookPro5,5 (...) Boot ROM Version: MBP55.00AC.B03 SMC Version (system): 1.47f2 (...)

Unfortunately, the Samsung MMDOE28G5MPP-0VA 128GB (rev. VAM0501Q) still hasn’t got TRIM.

That’s All Folks!
