Phison launches the first ever SSD controller to have built-in AI processing, along with some monstrous random data performance figures
When it comes to the world of PC gaming, a new SSD controller chip is unlikely to garner many headlines, as it's normally the solid state drives they're used in that are more newsworthy. But at this year's Computex event, SSD specialist Phison announced a new controller that is faster and more power efficient than the competition, and even has integrated AI processing to speed up…well…AI processing.
The controller in question is the rather unassumingly titled E28, and it's already picked up an award at Computex for its innovation. Manufactured on TSMC's N6 process node, Phison says the E28 sports random read/write rates of 2,600K and 3,000K IOPS, respectively.
To put those figures into perspective, the best gaming SSD, the new WD Black SN7100, only goes up to 760K and 1,200K IOPS in each case.
Even compared to Phison E31T, its best consumer-grade SSD controller, the figures are still mighty. That little chip, shown above in the Corsair MP700 Elite, can reach random read/write rates of 1,500K and 2,200 IOPS. The E28 makes it look positively slow.
Phison also claims that the E28 controller uses 15% less power than other 6 nm SSD controllers, although it doesn't specify which others it's comparing the new chip to. Either way, less power means less heat, and that's good news all around when it comes to ultra-fast storage.
Computex 2025
Catch up with Computex 2025: We're stalking the halls of Taiwan's biggest tech show once again to see what Nvidia, AMD, Intel, Asus, Gigabyte, MSI and more have to offer.
As to why the E28 boasts such monstrously high random data rates, it's because the chip is designed to be used in AI workloads and even comes with built-in circuitry for accelerating data flows during inference and token processing. Phison goes on to say that the integrated AI acceleration can reduce training times by as much as 50%, which is a pretty remarkable claim.
Of course, the E28 isn't aimed at the general public, least of all PC gaming. It's for mega-expensive, budget-be-damned AI workstations and servers, where the only thing that matters is raw performance.
However, while gaming SSDs are becoming ever faster in terms of sequential read/write bandwidth, they're still surprisingly slow when it comes to random operations.
The difference between the two is that the former involves a stream of continuous data, whereas the latter involves reading or writing data from all over the drive, in a constantly varying pattern.
Random data performance is key to making any PC feel snappy and responsive, as sequential throughput is mostly only helpful for loading a game or a level. The fact that the E28 has a random performance that's up to 240% faster than the current best gaming SSD means that a some point in the near future, ordinary SSDs are going to feel much more responsive.
So while the E28 is going to be the preserve of the professional AI market, its successors and siblings are going to bring all of its random goodness to the everyday world of PCs and gaming. Now that is newsworthy.

Lithium stocks soar after world's largest EV battery maker shutters mine in China
Lithium stocks soared early Monday after the world's largest EV battery maker closed its lithium mine in China, sending lithium prices soaring. The spike in lithium companies' stocks comes after Contemporary Amperex Technology (C7A0.F) announced early Monday morning that it was halting operations at one of its most important mines in China — also one of the world's largest — after its permit for the mine expired. The company said the Jianxiawo mine, the largest in China's Yichun lithium hub, will be shuttered for three months while it seeks to renew its license, according to Bloomberg. CATL is the largest EV battery manufacturer in the world, holding more than a third of the market. Shares of Albemarle (ALB) and Sociedad Química y Minera (SQM), the two largest lithium producers in the world, were up more than 11% and 9%, respectively, in early trading. Fellow major lithium miners and processors Lithium Americas (LAC) and Sigma Lithium (SGML) were up over 8% and 16%, respectively. The price of spot lithium was up nearly 4% on Monday; lithium prices have risen over 15% in the past month. Elon Musk's Tesla (TSLA) is one of CATL's biggest customers, according to a report from the Shanghai Metals Market. Tesla stock was up 2% early Monday morning. In January, the US Department of Defense added CATL to a list of companies it says are affiliated with the Chinese military. This would ban the Defense Department from signing procurement contracts with the company beginning in June 2026 CATL's move to shutter its mine will likely be seen as reflective of Beijing's increasing crackdown on "involution," which it sees as a phenomenon where increasing competitive prices for resources like lithium are self-defeating and end up slowing development instead of spurring it, according to the Financial Times. Lithium's centrality to the global market has exploded over the past few years due to the metal's key role in electric vehicles, storage capacity on power grids, and a variety of electronics, including phones and laptops. Demand for the metal could grow by as much as 40% by 2040, according to a forecast from the International Energy Agency. Lithium prices had fallen sharply over the past couple of years, hitting their lowest level since 2021 in June after dropping 20% from the start of the year, as mines around the world have continued to produce the rare-earth metal even as output has outpaced demand. Production in China alone has risen by 55% since 2023, according to data from commodities pricing agency Fastmarkets. "At this time, we see limited upside in the short term with a lack of pricing and market dynamics change, but also limited downside as we believe the market has bottomed out," UBS analysts wrote in a July research note. "This leaves investors in a 'no man's land', where trading and taking positions into equities is challenging." Jake Conley is a breaking news reporter covering US equities for Yahoo Finance.

TNB Tech Minute: Nvidia, AMD to Give U.S. a Cut of AI Chip Sales to China - Tech News Briefing
Full Transcript This transcript was prepared by a transcription service. This version may not be in its final form and may be updated. Julie Chang: Here's your morning TNB Tech Minute for Monday, August 11th. I'm Julie Chang for the Wall Street Journal. Nvidia and Advanced Micro Devices will give the Trump administration a portion of their artificial intelligence chip sales to China. According to people familiar with the matter, the administration will receive 15% of sales revenue as part of a deal to approve exports of Nvidia's H20 AI chip to China. Sources say the same agreement was reached with AMD for one of its chips. The agreement isn't typical and it came after Nvidia CEO Jensen Huang met with President Trump last Wednesday when Trump said, "Tech companies that invest in the US would be exempt from new chip tariffs." Meanwhile, Intel CEO Lip-Bu Tan, is set to visit the White House today after Trump called for his removal last week over his ties to Chinese businesses. That's according to people familiar with the matter. Tan is expected to have a wide-ranging conversation with Trump with the intent of explaining his personal and professional background. Sources say Tan hopes to win Trump's approval by showing his commitment to the country and pledging the importance of keeping Intel's manufacturing capabilities as a national security issue. And shares of video-sharing site Rumble climbed after the company reported its second quarter results and said it intends to make an all-stock bid to buy AI cloud computing group Northern Data for about $1.17 billion. Rumble stock was up 18% in early morning trading. Through Friday's close, its shares had lost nearly 40% of their value since the start of the year. That's your TNB Tech Minute. Join us again this afternoon for more.
