Installed Windows on second HD (SSD), now extremely slow

[pashunka]

I installed my new SSD as a secondary internal hard drive instead of SuperDrive and tried to install Windows 7 on it this way and it's now extremely slow and unusable.
I opened Bootcamp assistant and created Windows USB. Then it recognized that I have a second internal drive and I clicked continue. It created BOOTCAMP partition on SSD and restarted but went nowhere.
Then I read online that certain Macs don't boot off USB and that the drive you install on has to be in the main hd slot. So I put my SSD drive in the main hd slot and put the optical drive back. Then I booted through Windows 7 install CD and installed Windows on SSD. Everything seemed to be fine and I was able to boot to Windows.
I took the optical drive out, put SSD in its place and put the original HD back to original spot.
Now I am able to see Windows and OSX through REFIT and can boot into Windows but it is extremely slow and always freezes. I actually think that OSX became slower too.

Not sure if this was the correct way to install it so any suggestions are welcome.
BTW the SSD drive is brand new, so I highly doubt that it has issue.
I believe it's 2011 Macbook Pro.

Does anyone have any clue what's going on?
My goal is to have OSX on original drive and Windows on a second SSD drive.

Install Windows the way your computer supports. If it cannot be done according to your vision you might encounter problems you are facing right now. Swapping / changing booting HDU's or SSD' after OS install is certainly not the best idea.

What is the correct way to install Windows on a second internal drive?

I don't have a comparable configuration thus I still have the Superdrive in my MBP. I replaced the original HDU with a bigger SSD and have OSX 10.8.5 and Windows 7 SP1 ( Bootcamp ) on the same drive. Advantage is to still have an optical R/W drive and a FAST OSX & Windows, beside lower power consumption as well as increased resistance to magnetism and shock.

What about installing OSX and Windows on the primary ( in this case SSD ) drive ( you would need to swap again ) and storing your user data on the "old" HDU, accessible for both OSX and Windows ?

So I fixed the issue.
The problem was that the slot where optical drive was is slower than the hard drive slot. I read somewhere that it's 3GB/s vs 6GB/s in early 2011 models.
So I swapped the two drive and it works properly now.
