Just an FYI:Whoops, my bad, confuse pm963 with pm953.
Hm... Or not. Tough day.
Actually, I recall that I just compared with random writes IOPS. For read-intensive workload pm963 will be much better. For write intensive better (for 45%; I believe that sequential writes isn't very common case) but endurance leaves a lot to desire for this case.
And about Intel: could you share what platform are you using for such a build? Very interesting.
I messaged the seller about the PM963's. He sent pictures and info within 2 hours and accepted my offer for 4 drives at $300 each.
