Extremely slow boot times with Asus Zenbook UX32VD and Samsung 840 SSD

so today I bought a Samsung 840 250gb (not the pro version, regular) and replaced the 5200rpm harddrive with it expecting things to really improve.I installed windows on it using a USB external hard drive (With windows installer on it).

Windows is snappy, getting a 7.9/7.9 on Windows 7 Experience index and 250mb/s write speeds + 550mb/s read speeds when I test it.

However Windows takes more than a minute to boot where at it only took the 5200rpm HDD 30-40s to boot.

Bios is version 213 (latest)
Latest firmware for the SSD
AHCI Is enabled
All Asus latest Asus drivers installed.


Does anyone have any ideas why this happening?
I timed it at around a minute and twenty seconds for it to boot to desktop.

  1. Try using msconfig.exe to see if there's any bootup items you can disable. Open msconfig by holding Windows button + R and type in msconfig and press enter. Then go over to the startup tab and disable any programme that might cause delay on boot up. You can go over to the service tab and check the hide all microsoft services box and disable some start up services. Is the SSD still that slow once you get into Windows?

    Other than the drivers I installed for my laptop, it's a completely fresh install. And no, once I get past the Windows animation logo, the welcome screen comes for second and Windows is ready 1-2s later. It's very fast. As i've said i tested it with various programs and I'm getting the speeds advertised by Samsung. WEI is also 7.9.

  4. This problem is caused by built-in-motherboard iSDD

    There are 2 actual ways to solve this problem:

    1.Unsolder it (DO IT AT YOUR OWN RISK!) (http://forum.notebookreview.com/threads/ux32vd-issd-not...)

    2. Programm way:
    2.1 Go to Device Manager->IDE ATA/ATAPI controllers
    2.2 Replace Intel Rapid Storage driver with standart Windows driver (Standart ACHI 1.0 Serial ATA Controller)
    2.2.1 Click "Update driver software"
    2.2.2 Select "Browse my computer..."
    2.2.3 Select "Let me pick..."
    2.2.4 Select "Standart ACHI 1.0 Serial ATA Controller" from compatable drivers list
    2.2.5 Reboot on prompt
    2.3 Go to Device Manager->IDE ATA/ATAPI controllers again and locate 2 entries: ATA Chanel 0 and ATA Chanel 1. In my case ATA Chanel 0 was a HDD and ATA Chanel 1 was an iSSD.

    To determine what is on what chanel go to Chanel Properties and select Details tab. My HDD had an entry on drop down list named "Children" with text: "IDE\DiskINTEL_SSDSC2......", (I have replaced stock HDD with SSD) that tells You a model of Your curent drive.

    2.4 Disable the iSSD (ATA Chanel 1 in my case)
    2.5 Reboot
    2.6 Have a nice day

    Thanks JK for the idea (http://cookuop.co.uk/asus-ux32a-not-detecting-ssd/#comm...)
