    Hi
    I have a sony vaio z2 (vpcz22agx)and have bought recently a couple of crucial ssd 512 GB and a couple of enclosures (zyxel and icybox) in order to build 2 external usb 3.0 SSDs.

    Once connected to my desctop SSDs work pretty fine about 120-150Mb/s. I have tested by filling the whole 512 GB on both disks from my desctop. But when I connect to my sony vaio usb 3.0 and start copying - SSDs work for only a couple of minutes and then the system halts 1-2 minutes after transfer has begun until I unplug the SSD. One of the SSDs is already dead because of that.

    I have updated all drivers, bios and os on vaio z2, but it still doesn't help.



    Any suggestions?

    I'm sorry I can't find the thread but there was one talking about the Z2's USB3 port only providing USB2 throughput. I don't know if there's ever been a diy fix or if it needs to go back to Sony or if - most likely - it's an unsolved mystery that takes a bit away from the attributes of the Z2. Others, please chime in.

    Have you tried to update the SSD firmware? Seems like Crucial m4 problem. - most people got the freezing error fixed, few didn't.

    Did you change in bios the mode into AHCI ?

    A temp fix is running CrustalDiskInfo which will basicly increase your APM.

    A wise text from foreign forum

    That was me! Managed to solve it too.

    I unplugged all my usb devices then went to device manager, and uninstalled pretty much everything USB related - all the hubs etc. I then restarted and installed the latest drivers from the sony site - now getting massive throughput on the USB3.0 again :)

    Well, I updated the firmware for Crucial, it didn't help.
    I was looking for an AHCI option in my BIOS but it's not there.
    Running CrystalDiskInfo also didn't help - it doesn't even show the SSD connected.
    I will try the solution by Teknokid.

    Not as far as I know, as when you restart everything gets re-dedected and installs. Just make sure you have your power button set to 'shut down' in case you loose the track pad

    I tried the solution by Teknokid - it didn't work. I tried both SSDs (one with current firmware and one without firmware update) in 2 different boxings on 2 new VAIO Z2 and has exactly the same problem. Looks like SONY VAIO Z2 and CRUCIAL SSD just don't work together. Will have to switch to other SSD.

    Eventually, I made it work with the following:
    download the "USB 3.0: Renesas Electronics* USB 3.0 Driver"
    install the driver, it would install the renesas usb3.0 host controller utility
    open the utility (nusb3utl.exe) and check the box "disable usb 3.0 power management function
    TADA
