    G752VT - Installing a second SSD M.2 (DONE)

    Hi all.
    I'm not a SSD guru and my english is not good, but i would share my experience just hoping that could be useful for someone.
    I've bought a G752VT-GC173T equipped with a Samsung PM951/128GB (MZVLV128HCGR) as O.S. disk and a Hitachi HTS721010A9E630/1TB as second data disk.

    Since the G752VT has a second empty M.2 slot, my purpose was to install a bigger SSD (for the S.O.) using the original 128GB disk as an additional data disk.
    So i asked to italian Asus technical support for compatibility and i bought a Samsung SM951 256GB (MZVPV256HDGL-00000)

    This is what i done:
    1. installed the new SSD into the empty slot
    2. started the BIOS (F2 + POWER ON) to check that the new SSD was seen by the BIOS --> OK
    3. checked that the new disk was seen by "device manager" --> OK
    4. using "disk manager" i initialized the new disk as GPT
    5. format it as "simple volume/NTFS"

    At this point the new SSD was ready for some little test and it worked fine reading and writing some directories and files

    1. Now i was ready to "clone" the system disk on the new one, but unfortunately both "Samsung Data Migration Software" and "Samsung Magician" programs are incompatible with the new SSD disk so i decided to use "AOMEI Backupper Pro - Portable".
    2. The original PM951 has 3 partitions and this program allows to trim the partitions size on the new (bigger) disk to maximize the O.S. partition maintaining the size of the others 2.
    3. by the BIOS i set the new SSD as boot disk

    At this point the system starts good from the new disk without any visible or troubling problems

    After some hours i noticed an error ID 158 (disk identifiers duplicate) between the system events and i'm pretty sure that is because i "cloned" the original disk.
    So i decided to remove the original disk for a few days and set it aside as a precaution.

    When i will sure that the new system disk works perfectly, i will insert it into the PC and format it as a second data disk.

    BTW this is a speed test of the new disk (Samsung SM951/256G)

    Thanks for this. Will probably be doing this myself soon except with a 256GB SM961.

    But in truth, with those speeds of the original PM950 (especially the writes) it's not even worth putting it back in the laptop for use as a 2nd drive. It's too slow. I updated my 1TB HDD with a sata SSD which has around 500 for both read/write.

    So do you notice a difference in performance after upgrading to the new drive?

    I've bought my G752VT only 2 weeks ago and i don't used it a lot before the upgrade.
    In addition i was looking for more system space and not for better performances.

    So i can just say that using Adobe Premiere to make a video editing at 1920x1080 is very good now (but i have not tried it before) and that my speed tests seems to confirm that the performances are improved.

    P.S.
    After 5 days, still no any kind of errors shown by Event Viewer

    The SM951 will certainly show improvement over the PM951.**Not only a different controller but the increase is size helps.*
    A little bit of advice. Seeing how you have already removed your original drive leave it out. Do not format it. Leave it as is and put it away for a rainy day. So many posts on failures and ensuing clean installs that can all be averted by simply using the OEM drive to recover. *

    Did you need any new drivers or does windows use the same ones? Just wondering if I install an SM961 will I have any driver issues.

    Yes, this could be a good idea

    No BoutTime01, i've done exactly what i told in the first post, so i i've not installed any new driver.
    Furthermore, i chosen a Samsung SM951 only because italian Asus support told me that was the only M.2/256GB device certified by Asus.

    If you will install a SM961 please report your experience because i could decide to buy one as a second M.2 card.

    What model is your sata SSD and did you have any problem?

    Sandisk Ultra II. No problems at all. Only paid about £76 for the 256GB version.
