Hi all.


I just installed a Crucial M4 256GB SSD into the Superdrive slot of my 17in MBP with a caddy. I have formatted drive and copy all files from the HDD over to the SSD but the performance is so slow on boot. Before i installed it into notebook, I had the SSD connected via a USB dock and was able to boot from it fine. However after i installed SSD into my MBP, it takes quite a while to boot up off the HDD (3-5mins). After it boots, the SSD drive would not appear  on desktop for another minute or so. When accessing the SSD, i would get the colored spinning wheel and it waits before i am able to browse SSD files.


After installation, I then tried to set SSD as boot drive and restarted it. The MBP would not boot from SSD and then reverts to boot from HDD.

What is causing this? It is as if it has trouble initiating SSD, however SSD seems to work off cradle and USB just fine.
Does it matter whether I had SSD in main HDD bay or superdrive bay?


I used SuperDuper to copy files over.

The get info shows that the SSD is bootable.


Thanks in advance for your help.

    Does the ssd show up in the Startup Disk system preferences?

    Not sure but there have been many reports from many users about problems after installing Crucial SSDs. Specifically the M4 type.

    Is this a 6Gb/s drive? If so, that may be your problem. I believe even OWC warns that using a 6Gb/s drive in the opti bay is may or may not work, with the most likely outcome it won't. They recommend sticking with 3Gb/s drives in the opti bay.

    Hi All, I thinking of doing the same thing here.  If I move my old ssd drive to the superdrive bay will the Macbook boot from that drive?   I'm hoping I don't have to move all my info to the new drive and go through all of that ((Im running apps like Logic, Maschine plugins) and it would be a hastle if I had to re-install on the new drive.


    Thanks for any help.

    A SSD may not even work in the Optical bay. Some do and sopme don't. IMHO it is not the SSD used but the Optical drive and more specifically the cable and restrictions Apple places on that bay. Apple only want you to use a Slow CD/DVD drive in that bay so they use a very limited cable system and may restrict the speed of that bay in the firmware to only work with slower type disks/disc (slower HDD and or CD/DVD drives).




    That should of been.


    May not Work let alone Boot a OS from a SSD in the optical bay.

    Thanks Shootist007.  I checked my system further and the Optical Bay has link speed of 3Gb/s and connects at 1.5Gb/s so yeah that's not going to work I think.


    Now to plan B I guess and pull out the Toshiba and install a higher capacity Samsung SSD.  Just hate having to re-install Maschine, plugins etc.  Hopefully most works.  All of my stuff is legitamte but I'm hearing Native Instruments software is a bugger to move from drive to drive

    Doesn't really matter what your system Says it will handle. Most have a hard time getting a SSD to work at all in the optical bay. I thought I was making that clear in my last post.


    Good Luck & Best Wishes.
