Correct. But the OP will not see Crucial's advertised Read speeds of 500MB/s with AS-SSD.
looks like we're both correct. ATTO gives you maximum possible data rate (which you'll never actually see in the real world with data containing both ones AND
zeroes), and AS SSD gives you data rate similar to what you can actually expcet to see in the real world.
it's like a car that claims to get 55mpg - it may be true if you drove a consistent 40mph on a flat smooth cool dry asphalt just like at a michigan test track from which those claims come from, but in the real word of hills and stop lights and traffic and A/C that gets used ocne in a while the car will get less. i don't care what mileage my car can get under conditions perfectly suited for fuel economy, i want to know what mileage i'll actually get out of it when i drive it in the real world.
likewise, i want to know what AS SSD says, not ATTO.
