A few months ago, we covered proof of overclocking an off-the-shelf 2.5-inch SATA III NAND Flash SSD thanks to Gabriel Ferraz, Computer Engineer and TechPowerUp's SSD database maintainer. Now, he is back with another equally interesting project of modifying a Quad-Level Cell (QLC) SATA III SSD into a Single-Level Cell (SLC) SATA III SSD. Using the Crucial BX500 512 GB SSD, he aimed at transforming the QLC drive into a more endurant and higher-performance SLC. Silicon Motion SM2259XT2 powers the drive of choice with a single-core ARC 32-bit CPU clocked at 550 MHz and two channels running at 800 MT/s (400 MHz) without a DRAM cache. This particular SSD uses four NAND Flash dies from Micron with NY240 part numbers. Two dies are controlled per channel. These NAND Flash dies were designed to operate at 1,600 MT/s (800 MHz) but are limited to only 525 MT/s in this drive in the real world.
