Installed additional SSD to iMac 27-inch (mid 2011)

Finally found the time and patience to perform “Operation – Install SSD”. Basically, it is to install the Crucial M4 256GB SSD as a boot drive on the iMac 27-inch (mid 2011 model).

The Crucial M4 256GB SSD is going into the iMac 27-inch

The installation is pretty straight forward as long as you got the proper tools:

The entire installation took me close to 1 hour. Most of the time figuring out which screw go where as some of them are of different lengths (for the logic board portion).

New SSD as boot drive!

I would say it was 1 hour well spent considering that I got a faster boot drive now. It achieved 251.5 MB/s write speed and 505.9 MB/s read speed!

251.5 MB/s write and 505.9 MB/s read speed!


With the new Crucial M4 SSD, the technical specifications of my iMac 27-inch is now:

CPU 2.7 GHz Intel Core i5
Memory 32 GB 1333 MHz DDR3
Startup Disk Crucial M4 256 GB Solid State SATA Disk
Storage Disk Western Digital Black 1 TB SATA Disk
Graphic AMD Radeon HD 6770M 512 MB

I am extremely pleased with the new Crucial M4 SSD in the iMac as everything is snappier now. The iMac boots up in less than 30 seconds and applications launch almost instantaneously.

It is pure coincidence that Steve Jobs passed away 1 year ago, on this day (5th October). Well, take some time to remember the great guy and the things he have done to change the little technology gadgets we use everyday.

    What did you do about the high spinning fans?

    In fact quite a lot of people did not encounter constantly-full-speed fan when installing a additional SSD alongside the hard disk as the temperature probe still exist for the current hard disk.
