Hey there. Looking for a card that can take like 4 m.2 ssd's and have them show to windows as one drive.
I.E., 2x 512gb and 1x 1tb will show as a single 2tb drive
If you are using Windows, then any card that holds 4x M.2 drives and works in your motherboard will do the job.
Just use Disk Manager to put the drives into one volume. If the drives are different sizes, you can use "extend volume". If the drives are the same size, you can stripe them for more speed.
This is actually better than a proprietary board, since you could move the whole board to another Windows machine and read the data.
