    Hi all,

    Is anyone using a PCIE M2 SSD in a desktop PC right now and does it offer significantly better performance than a standard SATA 3 SSD?

    I'm buying a new desktop systemboard over the next few days and am wondering is it worth getting a board with an M2 PCIE slot for future use?

    Cheers:D

    I've test a few PCIe SSDs in work. Yes, they are faster. I've not tested them in M.2 format though.
    I don't know if I'd spend the extra cash on one though.

    I did some test last time and I might do some more tomorrow. I've put 20 Samsung EVO's SATAs in a server with 4 HGST PCIe FlashMaxIII's yesterday.
    I need to play around with raid configs and do some benchmarking.

    Cheers for the feedback Explosive_Cornflake. For the time being I'll be using a Samsung 850 SATA SSD but might might buy a board with an M2 PCIE slot for future use if there is a significant performance difference :)

    They can be faster, but unless you're running a write intensive db or something you wont see any difference. Certainly won't be noticeable with windows and day to day use.

    Samsung just released new PCI-E SSDs which have a write speed of 1500mb/ss on the pci-e v3 bus.
    Far as I know though you need the new intel cpu's for the extra pci-e lanes (i think they support 40 lanes as opposed to 36 for current models) as otherwise you'll losing on the graphics side..

    here's a good review on them
