Hello guys, I am a happy owner of a G751 laptop with the M.2 socket.
My italian version of the G751 comes with the 128GB SSD SATAIII hard drive and since I want to upgrade the hdd I bought the M.2 bracket (which I got today, finally!).
Now I have to buy a new M.2 x4 SSD and I have a doubt about the compatibility of this one:

HyperX Predator SSD PCIe Gen2 x4 240GB.

Is there someone who just tried the compatibility?
I'd like to buy (in case of problem) the Samsung XP941 256GB as an alternative.
Any suggestion is much appreciated.
Regards,

kalo86

You may just want to hold out abit, Samsung is coming out with the XP951 very soon and it will be twice as fast as the XP941

So far as I know, currently there's Samsung XP941, http://www.newegg.com/Product/Product.aspx?Item=N82E16820147349

But there're many new M.2 PCIE x4 SSDs coming soon with much higher write/read speed such as Samsung SM951

kalo86, the HyperX Predator SSD PCIe Gen2 x4is a new release, and is in the same category speed-wise as the Samsung XP941, but just a little faster on writes for the 480GB model - a little slower for the 240GB.

It isn't quite as fast as the new Samsung SM951, actually the SM951 is way faster than anything else out there, but we haven't had a benchmark from a G751, so only time will tell what the max performance will be.

So, depending on cost the HyperX Predator SSD PCIe Gen2 x4 might be a good buy over the Samsung XP941.

The SM951 will be faster, but as that part will likely be hard to get and overpriced for a while after release it might be cheaper and easier to get the HyperX Predator SSD PCIe Gen2 x4.

I tried replacing the 256GB XP941 from Samsung in my G751JY with the new SM951 version (bought from FLEXX memory, co, uk) but it wouldn't work. The computer couldn't see the drive. Considering this drive along with another sm951 512gb were intended for a desktop build I didn't waste too much time trying to find the problem. Perhaps I've mounted it wrong in the socket or should have changed something in the bios but from my 5 minutes fiddling with it, it didn't work.
The drive works perfectly fine in a deskop build now (X99 deluxe asus motherboard in the addon pcie4x connector adapter card with m.2 slot, as well as the onboard m.2 socket thats electrically connected direclty to the cpu via 4x pcie lanes).

The HyperX Predator M.2 looks like an interesting product, but when it comes to laptop machines, be aware of how much power it needs if battery life is important to you. I couldn't find a direct apples-to-apples comparison of power usage, but the officially published specs are useful:

HyperX Predator M.2: requires 1.38W Idle / 1.4W Avg / 1.99W (MAX) read / 8.25W (MAX) write
Samsung XP941 M.2: requires 0.08W Idle / 5.8W Typical
Samsung SM951 M.2: requires 0.05W Idle / 6.5W Typical and also supports L1.2 sleep mode using just 0.002W (2mW)

cheers, Rod

@RamCity, Can we intall Windows on the SM951 and set it as boot drive for G751 models that have M.2 connector?

There is another thread (https://rog.asus.com/forum/showthread.php?52546-Which-SSD-s-in-G751-and-what-can-you-replace-them-with&p=443181&viewfull=1#post443181) showing that the G751 comes from the factory with an XP941 installed, so that's the only one I would be super confident will work. Since the SM951 has no OPROM (like the XP941), it depends on the manufacturer to update the bios to recognise it.

Kingston SSDs use the crappy SandForce controller which can only achieve the advertised speeds when it deals with compressed data. That's why on the box of my previous Kingston HyperX 3K SSD it said "These results were achieved with ATTO Disk Benchmark" because it uses compressed data. But in the real world, I was getting around 170MB Read/Write, no where near the advertised speeds. I would never use a Kingston SSD even if you paid me.

upgrading from ANY HDD to even the slowest SSD would be a night and day difference. ANY SSD will blow an HDD out of the water. But when comparing these crappy Kingston SSDs with the high performers such as Samsung840/850 PRO or SandDisk Extreme II / SanDisk Extreme PRO / Crucial M550/Crucial MX100 they would leave the Kingstons in the dust.

you never know how much faster it would be until you try it

Just my 2 cents worth

Benchmarks:

ATTO Disk Benchmark-Windows 8 IRST 11.5.0.1207 (results look fine since it's compressed DATA which most data usually ISN:T compressed so this Benchmark that Kingston uses is meaningless in the real world):

Now, a real world benchmark....... watch how the figures suck so bad in write speeds when data is not compressed

Crystal Disk Mark-Windows 8 IRST 11.5.0.1207

AS SSD Benchmark-Windows 8 IRST 11.5.0.1207
