Ruler or Gumstick?
Samsung's drive is not long enough to label Ruler. More of a Gumstick.
Not much improvement over M.2 and dangerous in an environment with both,
The 1 U Long standard form factor is being developed by multiple vendors, not just Intel.
There is no standard called Ruler but 1UL was characterized that way.
The reason only Samsung makes Gumsticks is because they sized it perfectly for their NAND package size.
