480GB QLC SSD Modded into 120GB SLC! Lifespan Extended 30 Times

May 1st News - Nowadays, QLC flash memory has become more common, but many still yearn for high-performance, long-lasting SLC and MLC flash memory.

Computer engineer, TechPowerUp database maintainer, and tech guru Gabriel Ferraz has achieved a remarkable feat by transforming a QLC SSD into an SLC SSD, with impressive results.

He used an ADATA BX500, 2.5-inch, SATA interface, Silicon Motion SM2259XT2 controller (previously used SM2258XT), four Micron QLC flash memory chips, with a total capacity of 480GB (original flash memory capacity 512GB). s_bd4ecf231fa24a62a1d11878c8927d23.png

He used the familiar MPTools mass production tool to change the flash serial number, flash new firmware, and ultimately obtained an SLC SSD, at the cost of reducing the capacity to one-fourth, with only 120GB (original flash capacity 128GB). s_44532db847a94bd790081d1af1cfab20.jpg The modified 120GB SLC SSD now boasts an impressive lifespan of 4000TBW, approximately 30 times that of its original lifespan!

Due to the limitations of the SATA 6Gbps interface bandwidth, there is virtually no change in read/write performance, still peaking at around 500MB/s. However, there are noticeable improvements in latency and access time.

It remains to be seen whether PCIe TLC SSDs can undergo a similar transformation to achieve a dual leap in performance and lifespan. s_a51ed60734844ce9b53cca4d6fbf53cf.jpg
