I would give it a few hours to see if it settles back to normal, because after an update there are several background threads such as spotlight and time machine that'll be running and using resources on your storage device for the first few hours after an update.
I had that problem in testing. I reported it but it never got fixed.
Now I just wanna go back to 10.6.7... After more than an hour, SSD speed hasn't recovered :uncool:
I wonder if this update will fix the beachball symptoms/6G SATA Bugs?
My Vertex 3 is working fine with 10.6.8 on a 2011 15" mbp.
No, sorry. I was posting in response to the questions above about the ssd issues. Mine is working fine but I've never tried an optibay.In a 6G enabled optical bay?
