    Yes I use this card.

    You can buy them cheaper on Amazon.

    4x connector but only 2x electrical. max throughput with raided MSATA dives is about 700MBs.

    It is bootable

    No drivers required

    I found a marvel utility to set up the raid on the card but it was an old version of software and it only allowed 64kb blocks, so is used Mac OS disk utility to set up raid with 256Kb blocks because is use it for editing video.

    Cost wise, if you do not want more than 2GB of storage, I suggest buying a Lycom NVME adaptor PCIE card and a Samsung 970 2GB NVME ssd because it is almost twice as fast as the raided MSATA drives.

    If you're going down the msata route, not nvme, why not just get something like a P410 (or other similar raid card) and SATA SSDs - you'll get much better performance, and can easily run more smaller disks.

    "4x connector but only 2x electrical. max throughput with raided MSATA dives is about 700MBs."

    What doed that mean? I'm not familiar with these things.
    I plan to use the card with 4 x 1TB Samsung 860 pro's.

    It is to do with the connection to the mother board. The card has a 4x PCIE connector but not all the pins are electrically connected on the circuit board so you can't get the maximum possible speed from it.

    I have one of these cards with 3x Samsung 850 Evos 1TB ssds installed and the maximum transfer speed is only 700MBs. If the card had been designed with 4x electrical connections then you would have a possible maximum transfer around 1500MBs

    I edit video HD and sometimes have Multicam clips with 4 or 5 video streams and the card is fast enough for my needs.

    I bought it almost 2 years ago but if I were buying new I would consider the Amfeltec squid or Highpoint carrier boards which can take four NVMe drives. Search this forum for more info about the Amfeltec and Highpoint cards

    These boards are more expensive but they plug into the 16xPCIE slot on your motherboard (the long slot above the graphics card) and they have 16x electrical contact so you can get maximum transfer speed, but you need to buy the latest NVMe type ssd from Samsung , so you could potentially have 8TB of raided SSD running at 5000MBs !!!!!

    For just 4TB, IMO, buy a single 2.5" 4TB SSD is much easier, and you can still get 500MB/s. No need to RAID, much simpler setup, lower failure rate.

    But understand you will still need a PCIe carrier board to get 500MB/s transfer speed on a single drive.
    cMP SATA ports won’t make that kind of speed unless setup as RAID system with 2 or more drives.

    Correct, lots of PCIe SATA card out there can accommodate two 2.5” SSD. That can easily create a 8TB flash storage now. So, even only need 4TB. I will still prefer to buy a single 4TB SSD and a card, then still has an extra SATA III port that can accommodate another 4TB (or even larger) SSD later.

    By considering mSATA SSD is more expensive for the same capacity. I think a single 4TB 2.5” SSD + a good PCIe SATA III card won’t be more expensive overall.

    What if I set up 2 drives in RAID 0 on the PCIe card?

    If you mean the card for 2.5" SSD. Then depends on the card, it can deliver up to about ~960MB/s

    But I generally don't recommend that "high end" card. The card itself is quite expensive. Unless you really need something like 8TB SSD storage, and you can't afford 4x 2TB NVME, and you require something that can deliver more than 700MB/s, and you must achieve this specific setup in a single PCIe slot...... then there is not much choice but the Tempo SSD Pro Plus is the way to go.

    IMO, if you want large capacity SSD storage, the lower end Tempo SSD is good enough.

    If you want really high speed SSD storage, you better spend the money on the NVMe SSD, but not the adaptor.

    In my case it is a way to move to full SSD in my cMP. I read that NVMe booting is still not on the cards, unless very complicated manipulation. I'm a plug & play guy, so I'll wait a bit. In the meantime this card gives me 4 slots to put SSD's and bootable. An Amfeltec is overshoot for the moment.

    Yes this a Plug and play solution

    here is the part from amazon:

    If you want 4 different bootable SSD, then this is definitely one of the best solution, not the fastest one, but very balance in speed and cost.

    I was wondering what a striped raid of 4x1TB SSD would bring me as boot disk.
    I would have a constant backup via USB3 on external drive.

    Should be nothing special but protential more trouble.

    The max sequential speed on this card is known to be 700MB/s, not that much above a single SSD with SATA 3 connection.

    The 4K random read QD1 won’t benefit from RAID 0.

    So, there is virtually no benefit for a 4x 1TB RAID 0 partiton to serve as boot drive.

    A single 4TB SSD setup should be cheaper and more reliable.
