CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0.
At a deep queue depth of 32, Kingston's KC2000 has faster read performance than the Toshiba XG6, the only other drive in this list using 96-Layer 3D NAND. However the Toshiba drive has the advantage when it comes to writes.
At QD1 (1-Thread), Kingston's drive has a slightly better read and write performance than Toshiba's drive.
