I've been doing some reading on the M.2 PCIe NVMe SSD. This drive uses the PCIe NVMe bus interface to provide very fast data transfers. In contrast to the usual SATA SSD (which looks like a little block), these new drives plug into a mother board that has PCIe NVMe connectors. This SSD is faster than SATA SSD and PCIe SSD.
Here's a M.2 PCIe NVMe SSDs, available in different capacities...
Okay, now my question...
A common pc build uses a "boot" SSD that stores the OS and programs, and a hard drive to store data. But how about a build that uses two SSDs, one for boot, the other for data. For example, two M.2 PCIe NVMe SSDs: a 120GB or 240GB for boot, and a larger size (1TB) for data. Of course the MB would need to have two M.2 PCIe NVMe slots. The main drawback I see is the expense of using this type SSD.
Or, just use one large M.2 PCIe NVMe SSD for OS, programs and data? External mechanical hard drives would be used for backing up data.
Let me know if you see flaws in my thinking on this subject. But be nice about it, I'm a sensitive guy
