I am really confused by the various posts , I have following questions:

1.Q: some claim that CH71 is missing a ( metal support caddy / PCIE M.2 bracket ) for additional SSD? is this true?
A: according to MarshallR@ASUS in this post "Notes before buying a G751 series laptop": http://rog.asus.com/forum/showthread.php?52776-Notes-before-buying-G751-series. yes. the CH71 that comes with only 1TB HD will have no PCIE M.2 bracket.

2.Q: does CH71 support PCI-E M.2?
A. It seems it sure supports it. as OC_Agent said in this post http://rog.asus.com/forum/showthread.php?p=451734#post451734 : "
is it possible to install 2x2.5 SSD in RAID0 Mode ???
Stilom, I don't believe so. There is two separate drive bay and I don't think they can give you a raid arraw. However, one of the two drives bay has a m.2 socket working at full speed, making any RAID 0 configuration irrelevant.
"

3.Q: does CH71 comes with different specification? such as one spec with 1TB7200RPMHDD, another spec with 1TBHDD+128GB SSD?
NOT SOLVED.

4.Q: can CH71 with only 1TB HD shipped be upgraded with additional SSD?
according to https://www.youtube.com/watch?v=akjzKO4HfQQ&t=13m15s and http://rog.asus.com/375732014/g-series-gaming-laptops/gallery-g751-upgrade-guide/. We can see it should have the bay on the left empty, so it should be able to accomodate a mSATA SSD on the left bay. but because no PCI-E M.2 bracket/caddy is provided, you won't be able to just buy a M.2 SSD and install it.

5.Q: can anyone post a link to picture of a PCI-E M.2 caddy?
its in their official upgrade guide: http://rog.asus.com/375732014/g-series-gaming-laptops/gallery-g751-upgrade-guide/

---------------------------------
P.S. I will update this thread as my findings progress. ( I hope you dont delete my post again )

1. Correct it does NOT come with a bracket.
You can add a M.2 SSD but according to Marshall you need to 3D print a m.2 caddy to support because well.. ASUS 🙂
or you can make some custom support if you're good at that kind of thing.
2. Yes it supports PCI-E M.2 it has the connection in the first bay just like the DH72.
3. I've seen a CH71 with more ram but they all had the 1TB HDD. I believe the next model up DH72 has 1TB HDD and M.2 SSD
4. Yes you can upgrade to an SSD. There's a few threads here with information on transporting data from one HDD to another.

I am OP, why is my post deleted without any notice? what exact forum guideline did I offend?

Richdog · ‎12-02-2014

No idea why your post was deleted, but I think it is absolutely disgusting that our laptops come with an M2 slot, and yet we cannot get a caddy to add an M2 drive. I would in fact be very surprised if this was legal to be refused working access to a working feature.

ASUS need to resolve this asap or they are going to get a hell of a lot of backlash of angry users who have an M2 slot that they cant use, because someone at ASUS in their iunfinite wisdom decided: "hey I know, we will only provide a caddy for osme laptops and not others, despite that having all the same functionality".

Completely illogical, and in my opinion boils down to a contempt for the customer (ie: they don't care what we think).

Yes, it's called as G751JT-DH72, which comes with 1TB HDD + 256GB SSD (and still with GTX 970M)

See this thread, we've got finally some answer from a user.

He's installed the latest SM951 M.2 SSD (though he get's only 1400MB/s not 2GB/s as per the spec) and below that he manged to have a 2.5' SSD which is a SATA 3 (6GB/s), both of them in one bay, 2nd bay is SATA 2 (1.5MB/s) and he has installed another 2.5' SSD with a HDD caddy in the CD drive (6GB/s). So, it's pretty much possible and AFAIK this is only Laptop I've seen with PCIe + 970/980M card.

Be careful with your spec abbreviations. 6 GB/s (doesn't exist) is very different from the actual SATA3 spec, which is 6Gb/s (small "b", as in bits, not bytes), or about 8x slower than 6 GB/s. Which is why PCIe SSDs can hit 2 GB/s theoretically, though these ones max out at less than that, and SATA 3 drives seem to max out at 750 MB/s (though in reality it seems to be 600 MB/s for all the drives I've heard of).

I'm surprised he's getting 1400 MB/s, actually. I only get 1175 MB/s and many users here are posting that they get 1080 MB/s with the built in PCIe SSDs.

Thanks, though I know the diff between Gb vs GB, it was a mistake.

I've a quick Q.

I too just got my GT-CH71 couple of days back from costco, it doesn't have a M.2 connector. I was just wondering is it possible to still fix a M.2 ssd or it's not advisable ?

After searching these forums for a M.2 bracket I actually made a 3d printed M.2 bracket myself. Well i made 13 versions before i found one that was perfect but its on shapeways if anyone still needs one. It has an open top for heatsinks. It also leaves enough room for the 850 EVO to fit naked. With heatsinks attached i got an average 7 degree drop in crystaldiskmark with the SM951.

3d printed parts and accessories for the G751. You know you want something better than OEM ->https://www.shapeways.com/shops/aeolisio[SIGPIC][/SIGPIC]

Can anyone confirm does G751JT-CH71 have the upgradability to a PCI-E M.2 SSD?
