    Windows 8.1 has been fast on my iMac 5K Fusion drive. Even the boot time isn't so bad. Of course, SSDs are faster. Maybe something is not quite right with your installation? Try installing Bootcamp drivers again?

    If you have a Fusion Drive, that's normal.

    You might as well as get an external Thunderbolt SSD and run Windows off that drive.

    Instructions to get it running in UEFI, TB or USB:

    Connect external drive to Windows VM. You must have a Windows VM in VMware/Parallels.

    What you need:
    install.wim file (obtain this from your Windows ISO)

    Open elevated cmd.exe

    Note: All commands aren't case sensitive, including pathway to files.

    Type diskpart
    Type list disk
    Take note of the disk you want to select
    Type select disk 1 (if your disk is Disk 1)
    Type clean
    Type convert gpt
    Type create partition EFI size=100
    Type format quick fs=fat32 label=EFI
    Type assign letter=S
    Type create partition primary
    Type format fs=ntfs quick label=W2G (or any other name you wish for label)
    Type assign letter=E
    Type exit

    Open up File Explorer. In your C drive, create a new folder named WIN2GO.
    Put the install.wim file in this folder

    Back in cmd.exe:
    Type dism /apply-image /imagefile:C:\WIN2GO\install.wim /index:1 /applydir:E:\ (this process will take quite a while)
    Type E:\Windows\System32\bcdboot E:\Windows /s S: /f UEFI

    Restart your entire Mac. After the chime, hold down Option and when prompted to select your boot drive, select EFI Boot.

    Proceed installation normally.

    After installation, install Boot Camp drivers.

    Make sure you select the start up disk in System Preferences or Boot Camp Control Panel. You do not want the computer to waste time looking for a start up volume. The reason that Windows is slower than OS X is that OS X installs to the SSD portion of the Fusion drive where as the Windows partition is only allowed to be installed to the spinning hard drive portion.

    thanks, there is any way to make a short key of start up disc to the desktop or to the dock to not go through the preference menu for reboot?

    BootChamp will do that, and it's free.

    Even TB1 is fast enough, or even a USB SSD.

    Transcend makes pretty good ones.

    With a 960GB JetDrive from Transcend (USB 3), my boot time is just 14 seconds into Windows.

    Ask and you shall receive: http://www.amazon.com/Transcend-JetDrive-Upgrade-Macbook-display/dp/B00JKCHMP0

    It's meant to be put in an Ivy Bridge Mac, but I left it in the USB enclosure that came with it and used it as an external SSD.

    128GB of it is dedicated to Windows, another 128GB as an emergency bootable OS X partition and the rest of it is for storage and scratch space.

    Reads are around 430 MB/s and writes are around 380-400 MB/s.

    LaCie Rugged Thunderbolt enclosure will do.

    Slot in a Samsung 2.5" SATA3 SSD and you're good to go.

    Depending on how much you can afford, TB is always preferable because you can enable TRIM over TB, but not over USB.

    The LaCie enclosure works over both TB and USB.

    and

    http://www.amazon.com/LaCie-Rugged-...d=1420554871&sr=8-4&keywords=LaCie+Rugged+SSD

    Whether or not TB is faster than USB 3, that depends on the interface controller itself.
