    Installed a Samsung 850 Pro 256GB SSD in my M11xR1.
    All seems to be going well.

    Sequential Read : 268.281 MB/s
    Sequential Write : 259.870 MB/s
    Random Read 512KB : 257.661 MB/s
    Random Write 512KB : 253.506 MB/s
    Random Read 4KB (QD=1) : 27.438 MB/s [ 6698.8 IOPS]
    Random Write 4KB (QD=1) : 48.844 MB/s [ 11924.8 IOPS]
    Random Read 4KB (QD=32) : 121.006 MB/s [ 29542.4 IOPS]
    Random Write 4KB (QD=32) : 105.254 MB/s [ 25696.9 IOPS]


    I know it's a bit of an overkill, but figured I'm paying it forward and maybe in years to come the SSD will still be useful in another notebook.

    The M11xR1 500GB HDD is now installed in a NUC box .

    Update

    The M11xR1 had original 4GB of memory when the above CrystalDisk benchmark was run.

    Nice numbers. I have been waiting on the price of the 512GB SSD's to drop so I can put one in my R1. I mainly need it for storage space of games.

    It does raise some other 'dilemmas' in that my M11xR1 only has 4GB of RAM.
    In performance mode the SSD can make use of RAM with a write ahead buffer(guessing without reading the details), which means there is a chance real gains could now be made with 8GB of RAM.
    Those with more experience than me with SSDs will probably have a better idea, but looks like a distinct possibility.

    It's odd seeing a gain of approx ⅔ over the original Seagate 500GB HDD at ~90MB/s sequential read, but then knowing the SATA2/RAM/CPU is holding the I/O of the SSD(SATA3) back by approx ½ in the M11xR1.

    True, 512GB SSD would be a sweet ride for out and about, but I have a few local NAS for storage ....

    Which are accessed via an Intel 7260 Mini-PCIe wireless-AC card providing 802.11ac at peak bandwidth of ~300Mbits/sec.... using USB2.0
    Which means my 802.11ac bandwidth is gimped by about half as well...

    [ Little primal scream] Is there no end of the rule of half with an olde M11xR1... :)

    With the Samsung 850 Pro 256GB and Intel 7260 wireless-AC card, I am getting ~200Mbits/sec write(ftp get) to the SSD on a 150MB file from a QNAP NAS on a 1Gbit LAN.

    Using the same file we see ~255Mbits/sec read(ftp put) to the NAS(TS-253 Pro), where the NAS with 8GB of RAM, Quad-Core processor and dual 1Gbit access it making better use of I/O.

    The SSD in the M11xR1, has not made any difference (none expected) to network I/O as the USB2.0 PCIe Wireless-AC interface is the bottleneck.

    That's actually right, if you get a machine in the near future you might be able to pull the SSD out of this one and use it on the new one. So, it's a great upgrade :)

    Upgraded my M11xR1 memory to 8GB.

    I bought 8GB Corsair Vengeance Memory.

    So, with 8GB of memory I started to look for ways to make some use of it.


    I enabled the Samsung 850 Pro advanced Feature - Rapid mode.

    * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s]

    Test : 1000 MB [C: 32.7% (68.1/208.1 GB)] (x5)

    OS : Windows 7 Professional SP1 [6.1 Build 7601] (x64)


    Now this just seems to be insane I/O reads and writes AND the notebook is only SATA2.
    So how it's getting these I/O numbers even with write ahead and etc, I have no idea.
    BUT I do have 3GB of memory 'preallocated' out of the 8GB, where in the past I'd only have ~1.3GB of memory used with 4GB/8GB total.

    So something is making use of memory, which is a good thing me thinks.


    The M11xR1 also has an Intel Dual Band Wireless-AC 7620 Plus Bluetooth card installed as well which has shown peak throughput of around ~300Mbits/sec at times.

    Now just have to get a new/replacement battery and it's "Who's your Daddy" all over again. :cool:

    Attached is a PDF with the a CPU-Z memory timings of the new and original memory.
    I'm not so good with the brain thing, when it comes to memory timings so someone may be able to identify if the memory is as good/better/worse than the original 4GB.
