I just recently upgraded an Early 2007 MBP to an Intel 520 180GB SSD and keep getting system freezing for 30 seconds at a time. Especially when I use memory intensive tasks that uses the swap file such as scrolling through endless pages of image boards. I've tried to use Onyx and ran all the cleaning tasks. Any ideas on how to fix?
 
Did you do a clean install or did you restore from a backup?

I did a clean install and my system runs flawlessly. Maybe the backup is conflicting with the new hardware.
 
I did a restore using Disk Utility. I shouldn't have to do a clean install to fix this and that would take far too many hours to get back to where I'm at now anyways.
 
Disabling the swap file with Onyx makes the stuttering stop, but unfortunately the model only supports 4GB of RAM so I need to use the swap file. Any ideas why the swap file is causing this?
 
I just did a clean install without transferring any settings over and it's still freezing for 30 seconds. I've read that the Crucial M4 does this a lot too but a firmware update fixed it.
 
I had the same problem but with a OCZ Vertex 3 on my 2007 Macbook Pro. Did all the software tweaks to no avail. So I switched SSD manufacturers to Intel SSD and it works flawlessly.

You can try this route to see if the problem goes away. Try another brand.

Yes, there's no update for Intel 520s. I guess I'm just going to have to return it. I wonder if this has anything to do with the SATA I interface when the drive is SATAIII.
