We published a review of the Crucial M550 1TB already today, and we’ll fill in the gaps tomorrow. In this review, we’re focusing on the smallest capacity size in the M550 series, the 128GB. When Crucial released the M500, the big attraction was the new 20nm 128Gb NAND flash that allowed the company to manufacture large capacity SSDs at reasonable price levels. By doubling the capacity of the die, it took fewer die per SSD to reach the capacity points.
