Top card!
I just have to make do with a few less SATA ports than my previous card, but with the 3 slots for M2 drives, that shouldn't be a worry for very long.
I'm more than satisfied with the performance.
Tracking and delivery on time and in perfect condition: very professional.
I'd definitely recommend it!
