G750JH-DB71 Who has replaced the M.2 drives with larger drives?

Level 12
Hi, I am thinking about picking up a G750JH-DB71 and I noticed that someone said that the drives used for the boot RAID 128GB+128GB SSD are proprietary and not replaceable with standard mSATA SSD's. Is this true? Has anyone replaced the original SSD drives with larger drives?

Update: It turns out that the SSD drives in the JH are special interfaces, not mSATA. The closest name I can find that differentiates them is "M.2 NGFF SATA" or "M.2 SATA".

At one point it looked like A110 or X110 might be the unique name, but that is a more generic name for SanDisk SSD's, and includes 2.5" drives.

Recently I tried to purchase the 256GB version of the M.2 SSD, but no luck. And, with all the confusion about the form factor, the retail components place called and ordered what they thought was the right component and were shipped 2.5" 256GB SanDisk drives, I don't feel comfortable ordering off of Ebay - there are some listings that look correct.

The M.2 is longer and narrower than the mSATA boards, and the M.2 has a distinctively different socket/fingers layout.

Here is the original page + a photo of the M.2 NGFF on the left, and typical mSATA boards on the right:

First time poster so be kind....! Shelled out $2500 for UX301LA Dec 2013, freezing then tanked at 13 mos (on a 12 mo warranty of course). Same 128 SanDisk M2 Sata x 2, RAID 0. Concluded one of 2 disks bad. Wasn't connectors, good disk worked in either slot. Changed BIOS to ACHI, clean installed 8.1 on good disk and had working computer with 128G for $2500. Not happy.
Wikipedia article very helpful re earlier posts: http://en.wikipedia.org/wiki/M.2. M2 successor to MSATA, different size/shape vs. SanDisk OEM's have "B&M" key connectors. Per article, the installed M2's were 22mm x 60mm, but most M2's for sale are 80mm (tape above). SanDisk makes it hard to find "OEM" disks, don't sell directly, contact mfg. ASUS sent predictable blow off email, suggesting I contact SanDisk or send to repair out of warranty.
Found M2 SSDs on AMZN, but many shapes and sizes. Went to Transcend website, M2 SSD category. "MTS600" series is specifically 22mm by 60mm, up to 512Gb. Replaced bad SanDisk with 512, works great. Did not reinstall RAID (edge of my knowledge base ?advantage) but no evident performance change and triple the storage with 512 Transcend as ACHI dynamic volume.
Hope this is helpful.

After reading everything I could regarding the G750JH that I have, I thought I had enough
information to make the plunge into changing the two 128gb raid 0 drives. The following is what I did -
I hope it helps.

I called Crucial as they have an m.2 500gb 2260 drive - the G750 computers do take 2260. If you get 2280
it will be 20mm longer - and I didn't want to get involved in making a bracket for them. Crucial tried to see
if the current SanDisk drives were SATA or PciE and couldn't find out. There was a post I read somewhere that somone
posted the G750 was Sata - and the 751 was PciE and Sata. They did tell me they ofer a 45 day return and said I can
try it all out - so I did. Keep in mind that if you decide to get other drives they cannot be PceI - they absolutely need to be SATA.

I ordered two of the following - CT500MX200SSD6.PK02 Crucial MX200 500GB SATA M.2 Type 2260DS SSD.

I did a backup/system image of the drives as a single drive - just like doing it as usual. I sent this to a USB hard drive.
I also made a reboot CD right through windows - it is an option in the backup window.

I then replaced the 2 drives with the 2 Crucial drives - then I rebooted and pressed F2 to get to the Bios. I changed the
Raid to AHCI - I also did change the boot sequence to CD/DVD - this was very important.

I put the disk in the drive and rebooted. I let Windows come up - and I reinstalled the image file to the new drives.
It all worked well.

I went to disc management and allocated the second drive as a D drive. The one issue I had was that the new C drive was cut up
into a system partition which I needed - this was the block on the far left. Next was the C drive OS itself - this only had about
227gb allocated to it - I think it just matched what it saw from the two raid 0 drives. Next to that was a Restore 450mb partition -
then next to that was another 230gb or so unallocated partition.

I could not expand the C drive to include the unallocated partition as it was not the direct block to the right. I looked at the 450mb partition and there was nothing in it - and after checkcing around I found it was OK to delete it with the Diskpart command in a
C prompt. Here's a link from what I found on youtube:

https://www.bing.com/videos/search?q=how+to+erase+restore+450mb+partition&view=detail&mid=B774A298C3...

So - I erased it - it disappeared - and I was able to expand the C drive to include the unallocated partition - and now
my new C drive has plenty of space.

I did not set these drives up as raid 0 - just as regular drives.

Everything works well. Keep in mind the drives are $179 each right now. I didn't think that was too bad to get this extra space.

Hi
I am writing to anybody who can help with a similar issue
After purchasing in 2014 an Asus G750JH under warranty and after 3 months of real usage i found myself locked in bios
Immediatly i send the notebook to asus support and after numerous visits there they told me that they had to change the motherboard and the one of the two proprietary ssds
Today i find myself in the same situation and i want to replace totally these ssd setup even with my own ssd or even with an hdd since i am fed up with asus support i will not send them the machine for service
Has anybody succesfully installed their own ssd to the place of the proprietary ssds?
Do i have to purchase this adapter?
Is there an other way to do it?
Does anybody know how i can find out my original purchase motherboard number in order to see if they really changed the motherboard (there is a big chance they never did)
I can only say definetly due to malpractice done i do not trust asus support in anything
When i asked the first time to change both proprietary ssds they were laughing telling me that there is no need to do it with the result of loosing many files needed for my work
I am not writing to deal with some representative of asus i despise them in many ways since the machine was brand new and had very few working hours and a 2000 euro machine should at least do its job
The asus support in Greece is a joke but i am writing to find a solution since they cannot
Solutions i have in mind replace again one of the proprietary ssds and hope for the best
Replace all this adapter with my ssd of my choice
Replace the total of ssd technology with a second hdd or even leave just the one hdd that is already there (yes you can say i do not trust ssd technology anymore and this setup by asus )
Final question anybody that has done some kind of modification:for how long are you running it? Are you satisfied? What did it actually cost you?
Thanks!

I think this may be a decent replacement. I'm looking to double the size because I only have about 55 GB free on my 256 GB boot SSD - everything wants to install on your C drive! And even if you install elsewhere, many put a lot of stuff on C anyway! And your profile (app data) HAS to be on C too - thanks MS!

Anyway, have a look ...

Can anyone offer an opinion on whether 2 of these will replace the 2 -128 GB SSDs?

I'll also try to avoid reinstalling Windows (and all my apps - what a pain!). I have carved up my 1 TB hard drive into 4 drives: D, E, R and T. T is a second instance of Win 8.1 I use for testing apps I develop. I was thinking that after booting into the T drive, with a USB SSD reader/writer like this, I may be able to copy my C drive to the new SSDs using the writer.

Anyone think that'll work?? Will the MBR and other partitions on the C drive get copied? I'm thinking perhaps not, but that's not my wheelhouse ...

Worst case, if it doesn't work, I can always just do the whole reinstall thing ... 😞

Howdy Guys,
Been reading up on this thread and*enjoying all the team work here. I also have the g750JHA and was wanting to upgrade the two 128's and possibly the 1tb mech drive to ssd. Just need to save my pennies a bit longer. Again thanks for all the work done.
Have a merry Christmas and Happy ROG_n

OK, to review, my G750JH-DB71 came with a 256 GB SSD C Drive and a 1 TB 7200 rpm hard drive. The SSD was 2x128 GB M.2 SATA modules set up in RAID 0. These were 2 SanDisk SD6SP1M-128G-1002 modules. They look like this:
61125

The SSD is my system drive, which contains my Win 8.1 Pro installation, and it was getting tight on free space (only about 15% free), so I needed to increase the size of that drive.

I used EaseUS Partition Master (free version) to examine the partitions on the original SSD:
61124

NOTE that my 1 TB drive is DISK 0 and the C Drive is DISK 1 (listed as DISK 1 and DISK 2 in EaseUS). This seems unusual, but there it is ...

I bought 2x256 GB Transcend M.2 SSDs from Amazon for $107 each: https://www.amazon.com/gp/product/B00KLTPT6A/ref=ox_sc_sfl_title_3?ie=UTF8&psc=1&smid=B00KLTPUG4

Obviously, I had to be cautious because the drive being replaced is my SYSTEM drive! So I used NovaBACKUP to make an image backup of the C Drive and to create a bootable image restore USB stick. (I use NovaBACKUP for my regular backups)

I tried to use the free MiniTool Partition Wizard to make a bootable partition editor CD, but I could not get my machine to start the partition editor after rebooting the CD. So, I paid for the upgrade of EaseUS (the free version won't make a bootable CD) and made a bootable CD that would run their partition manager. There is probably another free utility out there to do this but I wanted to get this DONE!

So I swapped in the new SSD modules - they just popped right in! I then booted to the BIOS screen (actually the UEFI screen) and configure the 2 new SSD modules in RAID 0. Then I booted the partition editor CD. The new disk was there All I had to do was to convert the disk to a GPT volume (as opposed to an MBR volume, which seems to be the default).

After that I booted the image restore USB and did an image restore to the new disk.

Then the machine just booted Windows from the new drive ... just like that!!

Of course the partitions were the same as the original SSD, so my new C drive was the same size (256 GB) as the old one and there was a bunch of unallocated space on the new drive. I used the EaseUS partition editor to allocate that space to the system partition. To do that, I had to first move partitions around a bit so that the unallocated space was adjacent to the system partition. Then I just expanded the system partition.

My C Drive now has 249 GB free (55% free) ! 😄

I love it when a plan comes together!

OK ... the above is the short version. I actually made a number of mistakes along the way, and had to learn what to do by trial and error. The saving grace is that I could keep swapping the original SSD back in so I could boot and google more research! I skipped all that and just wrote up the summary of what actually needs to be done to work right.

I hope this helps someone!

Happy Holidays to all!

I'm probably late to the game since I just joined but the ngff in "G750JH_SATA_NGFF_SSD" was the original name for what is now called M.2 ssd here is a link to a review of a similar ssd from SanDisk http://www.thessdreview.com/daily-news/latest-buzz/sandisk-x110-m-2-2260-ssd-provides-robust-speed-p...
Looks like this one from crucial may work as well http://www.amazon.com/gp/aw/d/B00HBKN2GG?cache=50f65b3f406e74df08f84a4526fefd71#ref=mp_s_a_1_2&qid=1... but until I get my g750jh I can't test it 😞

Thanks for the links al441j 🙂

I have spent some time recently with a local components chain, trying to get the SanDisk 256GB M.2 NGFF cards, with no luck. Glad to see another company besides SanDisk is making M.2 NGFF components, especially happy now that I found the 480GB model:

http://www.amazon.com/Crucial-M500-480GB-6Gbps-Internal/dp/B00HBKM6UO/ref=sr_1_2?s=electronics&ie=UT...

I am hoping that more companies will make M.2 NGFF components. It would have been nice to be able to get the new Samsung Evo mSATA in the M.2 NGFF form factor.

Does anyone know what Asus is going to be using moving forward, on the JH replacement, likely the JZ? Has Asus stayed with M.2 NGFF or moved to mSATA or something else? I would be disappointed to get fitted out with the M.2 NGFF components, and then have Asus move to another incompatible form factor that I couldn't migrate my new large M.2 drives to the new laptop.

Here are some shots. First one shows the Msata removed. The next shows the four screws that need removed in order to remove the drive. The 3d shows the ribbon holders. Flip bracket up to remove the ribbons. The fourth shows the tape removed and the ribbons flipped back from their appropriate spot.

Now that we have identified the M.2 NGFF form factor for the SSD's, and we can get larger 256GB/480GB M.2 NGFF SSD's than the stock 2 x 128GB, doesn't the performance improvement from being able to have a hardware RAID0 for 2 large M.2 NGFF SSD's + 1 2.5" drive outweigh the benefits of backing down to a 2 x 2.5" straight SATA3 configuration?
