Hi,
Recently bought 240GB Intel 530 SSD for my Late 2011 Macbook 13. That was a complete failure -
2-3 minutes long boot, constant 5-10 second freezes / beachballing, disk missing on reboot.
Luckily I found this thread, and have been watching it for a while.
After applying DC32 boot now takes 20 second and seems it fixed reboot issue, too. Still i experience minor 1-2 second freezes.
Anyway, thank you guys for all of your help! Keep up good work.
I will post later after several days of testing.
