Product description

Make sure this fits by entering your model Number. As media's ASM2824 has a PCIe 3.0 x8 upstream port as well as 4 PCIe 3.0 x4 downstream ports. The switch is designed primarily for storage devices. SI-PEX40129 card uses ASM2824 switches and therefore does not rely on PCIe bifurcation supported by CPU or PCH (they will work on closed end systems that have limited PCIe bifurcation capabilities). dedicated PCIe 3.0 x16 bus bandwidth fully maximizes NVMe SSDs performance delivers unprecedented fast transfer speed via intelligently aggregated dual x16 PCIe 3.0 Bus bandwidth NVMe RAID is supported base on the motherboard chipsets the I/of crest SI-PEX40129 is a great accelerated secondary storage solution for any workstation with true PCIe 3.0 x8 bandwidth (x16 interface). It has two M.2 NVMe ports to accept two NVMe M.2 SSDs, so each NVMe M.2 SSD has dedicated PCIe 3.0 x4 bus bandwidth. It delivers transfer speeds 20 times faster than SATA SSDs. By by-passing the traditional PCIe 3.0 x4 NVMe solutions, Using the SI-PEX40129 will allow user add 2 m.2 NVMe into any non-bifurcation PCIe x16 slot to achieve their full potential with a bandwidth of up to 6, 500 MB/s. Unlike on-board DMI 3.0 based NVMe solutions or single NVMe PCI-E x4, which are forced to share a single PCIe 3.0 x4 lane with the motherboard's data ports, The SI-PEX40129 combines 2- m.2 drives to be able to run on PCIe 3.0 x16 lane. This unique architecture allows the drive to interface directly with the platform's CPU, which provides PCIe x4 bandwidth for each NVMe SSD!.

    4.0 out of 5 stars MAC PRO / CMP 4.1 ---> 5.1 NvME Solution - Blazing fast speed and running cool on a 12 Core Mac Pro
    Reviewed in the United Kingdom on 8 August 2020
    Just upgrade my machine from a single Qaud processor to a dual 12 Core 3.46 and ordered this and 2 x 1 TB Samsung EVO 970 Plus on Friday and got it Saturday afternoon so shipping was fast and snappy.

    Packaging was good and documentation was sparse but I get that. Shiny brochure instructions mean additional costs.

    The only thing that let this products down is the screw removal process to separate the heatsink from the board.

    Approach removing the screws with caution as to avoid a stressful upgrade session!

    The screws are so small and really not that deep to get a screwdriver into and for them all out except for two which due to the weak format of the screws stripped.

    Really annoyed at prospect of having a bit of kit that I was not going to be able to ultimately use as i couldn't open the thing and at the same cursing the way the screws were inserted at source / designed to strip if you use a normal amount of force to untighten.

    1 of the stripped screws somehow managed to swivel out and eventually came free, however one of them was just too stripped to have anything fit and be removed and this 1 decided to try and thwart the plan .... however the design of the card meant that I could swivel it in a way that got everything out into the open and i was able to install the blades and remove the sticky blue tape coverlid the heat absorption material that looks like chewing gum ( I am making a conscious effort to not leave a super technical review so even a layman can understand ).

    Important to note that if your a first timer tinkering with this type of things, the slightly bigger gold screws in the bag are like mounting pillars to get your NvME put to eh same level as the connector that its plugs into, so you put one of them under the blade and then screw into it from the other side so its firmly and securely held into place.

    Before I install the device, I went through the process of updating my 2009 CMP to the Move firmware.

    This is different form flashing a 4.1 to a 5.1 and involves you downloading the Mojave installer and then updating firmware by following the instructions.

    If you are NOT wanting to install Mojave when your computer restarts then click cancel when your machine reboots and it enters into the Mojave installation dialog.

    Once I confirmed that my firmware was updated, I then installed the card into the second x16 slot as my graphics card was larger and occupied the bottom space and once everything was seated and secured correclty, I rebooted the machine and was happy to see that the disk were both recognised and I erase/ formatted them and ran a speed test using Blackmagicdesign Speedtest and the result for an 11 year old Classic Mac Pro are nothing short of fantastic and for me personally, I feel it solidifies the Classic Mac Pro as the greatest desktop Apple ever built as the scope for upgrade through this lovely bit of kit is nothing short of amazing.

    Enjoy !
