Overclocking SSDs: Significant Performance Boosts Come at the Risk of Potential Degradation or Data Loss

 

How to Overclock an SSD: A Detailed Exploration by Hardware Enthusiast Gabriel Ferraz

If you've ever pondered the idea of overclocking an SSD to boost its performance, Youtuber Gabriel Ferraz has taken on the challenge and documented the entire process. Ferraz, a hardware enthusiast, shares the step-by-step journey with sufficient details to showcase the overclocking process and the resulting performance gains.

Ferraz approaches this experiment driven by curiosity, a trait familiar to hardware enthusiasts seeking to push the limits of their devices. The video offers insights into the SSD selection process and the outcomes achieved within certain limitations.

Choosing an unconventional drive labeled RZX Pro 240GB DRAM-Less SATA-based SSD, Ferraz avoids NVMe SSDs, as their performance is already optimized, leaving little room for visible improvement through overclocking. The selected SSD utilizes a Silicon Motion SM2259XT2 controller, a pivotal element in this overclocking venture. The controller, initially clocked at 425 MHz, features a single-core ARC 32-bit CPU with a maximum clock speed of 550 MHz. Ferraz zeroes in on the SM2259XT2's overclocking potential to enhance performance.

The SSD employs a specific 96-layer Kioxia (formerly Toshiba) TLC BiCS4 256Gb NAND, rated to run at 400 MHz. Ferraz emphasizes that SSDs operating below certain specifications may serve specific purposes like endurance or power consumption considerations. Alternatively, these chips might not meet strict quality control standards and are often sold to smaller-tier SSD manufacturers for localized markets.

To embark on the overclocking process, Ferraz uses a SATA to USB adapter with a JMS578 bridge controller and a clamp, tapping into Mass Production Tools to program the SSD with compatible firmware. This intricate procedure demands technical expertise and a series of trial-and-error adjustments to achieve optimal stability and performance for benchmarking.

Ultimately, Ferraz succeeds in stabilizing the controller at 500 MHz, marking a 17.6% increase. The NAND experiences a more significant boost, reaching 400 MHz, reflecting a remarkable 106% increase.

Initial benchmarking using CrystalDisk Mark, 3DMark, and PCMark 10 shows no sequential read/write performance increase due to SATA III limitations. However, Ferraz observes a slight latency decrease and noteworthy improvements in random read and write performance, rising by 27% and 10%, respectively. Performance gains extend to 3DMark and PCMark 10, but Adobe Premiere Pro 2021 and game loading times, as well as a 6.20 GB ZIP file transfer, remain unaffected.

Ferraz delves into temperature and power draw, noting that the overclocked drive operates at a higher temperature (45 degrees Celsius) compared to the stock settings (40 degrees Celsius). Despite avoiding thermal throttling, the efficiency of the overclocked drive decreases by almost half, with max power draw escalating from 1.16 to 2.01 watts. The SSD ultimately succumbs to the strain of the benchmarks.

In conclusion, Ferraz's experiment illustrates that, with the right tools and knowledge, any device with a clock speed can be overclocked. While the process may not be suitable for all SSDs, Ferraz's endeavor provides valuable insights into the possibilities and challenges of overclocking SSDs at home.
