    I have a dell inspiron 5567 with 1TB mechanical hdd. I am planning to install an ssd of 128GB and set it as boot drive.
    Now as this laptop do not have M.2 slot, i have an option of using a M.2 caddy to install M.2 SSD in either optical drive slot or internal hdd area.
    I need suggestions to choose between M.2 SSD ( like Samsung EVO 960/970) or a 2.5'' SSD ( like Samsung EVO 860). In either case, my selected drive will be used just for booting.
    Keep in mind, I dont have a M.2 slot, i will use a M.2 caddy.
    Thank you in advance :)

    waste of money, M.2 caddy is the same speed as normal 2.5" SSD.

    Most people dont have a a specific need for m.2 speeds to begin with.

    Just get a regular Sata3 SSD and call it a day.

    Dont forget that you cant use an NVMe SSD in a caddy and expect it to work, you need to use SATA m.2 SSD's.

    A normal SSD will not achieve the theoretical SATA 3 speed of ~750MB/sec, will a NVMe SSD achieve ~750MB/sec when plugged into SATA 3 port using an adopter, converter or caddy?

    Pci-e and SATA drives use different signaling, you can't put pci-e into SATA. Also while that's the theoretical max once you take real world values into account just over 550MB/sec and is the best you will see.
