Semiconductor Brief: Kioxia’s 157 PB Rack, Phison Controllers and Memory Safety

Semiconductor Brief · November 12, 2026
Research checked through November 12, 2026, at 09:40 a.m. Pacific. This first edition covers announcements from November 6–11.

A dense flash-storage rack, rising SSD-controller shipments, stronger foundry revenue and new memory certifications give us four different views of the chip industry this week. The common thread is infrastructure: how much data a system can hold, which components are shipping, and what qualifications hardware needs before it reaches demanding environments.

This is the first edition of DrivesHero’s Semiconductor Brief, a twice-weekly look at chip news with a focus on storage and the technology behind it. Here is what the companies announced, followed by our interpretation of the implications.

Kioxia and Dell put 157 PB of raw flash capacity in one rack

The announcement: Kioxia said on November 11 that a Dell ObjectScale configuration combines 640 of its LC9 245.76 TB SSDs across 16 Dell PowerEdge R7725xd servers in a standard 42U rack. The company describes the result as the first single-rack object-storage solution with 157 PB of raw flash capacity. That record claim comes from Kioxia; it is not an independent DrivesHero finding. Read Kioxia’s announcement.

The arithmetic is 640 × 245.76 TB = 157,286.4 TB, or approximately 157.3 PB using decimal units. That is installed raw capacity. Protection overhead and system configuration determine how much usable storage an operator actually gets.

Our take: The story is enterprise storage density, not a new laptop upgrade. The 245.76 TB model uses the E3.L form factor and QLC flash. Our guide to QLC, TLC and MLC NAND explains why flash type matters when evaluating a drive. Buyers should also examine workload suitability and protection features, as discussed in our enterprise versus consumer SSD guide. The rack announcement alone does not establish a consumer price trend.

Phison reports a jump in PCIe SSD-controller shipments

The announcement: In its November 6 update, Phison reported that its PCIe SSD-controller shipments rose 35% month over month in October. It also said products in its “AI Ecosystem Modules” category contributed more than half of third-quarter revenue. Those figures describe different reporting periods and measures: October shipment units and a third-quarter revenue share. Read Phison’s report (PDF).

Phison’s AI category includes several product lines and applications; it should not be read as enterprise SSD revenue alone. Likewise, the controller shipment increase measures Phison’s business, not the entire SSD market.

Our take: For storage readers, controllers deserve attention alongside NAND capacity. Our SSD controller guide explains their role in drive behavior. This update is a useful supplier-level demand signal, but it provides no basis for assigning a 35% improvement to drive speed, availability or retail value. Those questions require product-specific evidence.

TSMC’s October revenue rises, with limited detail for storage buyers

The announcement: TSMC’s November 10 monthly report put October revenue at NT$586.89 billion, up 14.7% from September and 59.7% from October 2025. These are company-wide monthly revenue figures. Read TSMC’s October revenue report.

Our take: The figures add a broader foundry perspective to a column that also follows memory and storage components. They show growth in TSMC’s reported sales, but the release does not provide a storage-controller product breakdown. It therefore cannot tell a drive buyer how many particular controllers are available or what an SSD should cost.

Revenue also differs from production capacity: one monthly total does not reveal how much additional manufacturing capacity has become available. We would look for more detailed operational disclosures before drawing conclusions about particular component supply chains. The monthly release does not establish a single cause for the increase.

SK hynix adds safety and cybersecurity credentials for LPDDR5X

The announcement: SK hynix said on November 11 that its LPDDR5X DRAM obtained IEC 61508 SIL 3 functional-safety certification, alongside ISO/SAE 21434-based Cybersecurity Management System certification. Its announcement identifies SGS-TÜV Saar as the certification body and discusses applications including robotics, industrial systems and vehicles. Read SK hynix’s certification update.

Our take: This story concerns DRAM and its qualifications for demanding systems, rather than a NAND flash or SSD launch. Functional safety addresses unintended failures; the cybersecurity management credential concerns processes for managing security across the product lifecycle. The scopes matter and should be assessed separately.

Neither credential is a promise that every device using the memory will be failure-proof or immune to attacks. For readers following industrial and automotive computing, the useful question is whether a component meets the requirements of a particular system design. Certification news answers a different question from a consumer performance benchmark.

What we will watch next

For the storage-density announcement, the next useful evidence would be deployment details, usable capacity and workload measurements. For controllers, it would be product-level availability and independently measured performance. For foundries, more detailed disclosures could clarify the mix behind revenue changes. These are questions for future reporting, rather than outcomes established by this week’s announcements.
