  • Hybrid drive not booting faster than a normal HD

    - by Nigel Trotter

After copying the image to the hybrid I had to resize the partition, which was fine but after rebooting a few times to "teach" the hybrid, I have no increase in boot speed.

That's a problem since I'm a home user and will probably add one disk a year tops. But what if I set copies=3 against my entire pool and just throw individual drives into the
