my computer currently using 1 HDD 1 m.2 Sata SSD and 1 M.2 sata SSD with 2.5" adapter, there is one pcie only slot on my motherboard. made a mistake thinking i could plug M.2 Sata to Pcie only slot hence the M.2 to 2.5" adapter.
but right now i am away from my computer, i could get SSD for sizable discounts, was thinking to buy M.2 Pcie and 2.5" SSD, use it as external storage for now then plug it into my motherboard when i am back.
i thought i could buy M.2 enclosure and use PCIE SSD now and swap it to my existing SATA SSD later when i need it.
