Kioxia LC9 SSD: How a Tiny Drive Now Stores a Staggering 245TB!

Forget everything you thought you knew about data storage. Kioxia has just pulled back the curtain on its groundbreaking LC9 Series SSDs, featuring an astonishing 245.76 terabytes (TB) of storage capacity in a compact 2.5-inch drive. This isn’t just an incremental upgrade; it’s a massive leap forward that makes traditional hard drives, like the new 30TB models from Seagate, look like ancient relics. Get ready to see how Kioxia’s latest innovation is packing unprecedented amounts of data into unbelievably small spaces.

The Astonishing Capacity of the Kioxia LC9 SSD

Imagine an SSD – a solid-state drive, known for its speed and compact size – that can hold nearly a quarter of a petabyte of data. That’s 245.76TB, enough to store tens of thousands of high-definition movies or virtually every photo you’ve ever taken, along with those of your entire neighborhood, all on a drive that fits in your hand! This incredible capacity from Kioxia’s LC9 series is available in the familiar 2.5-inch form factor or the newer, optimized E3.L “ruler” form factor, designed for modern server racks. For those wondering, an E3.S version is also available, though it currently maxes out at a still-impressive 122.88TB.

While the Kioxia LC9 is a PCIe Gen5 NVMe SSD, meaning it connects super fast to your computer or server, its focus isn’t necessarily on handling countless small, random write tasks (measured in “IOPS”). Instead, these colossal drives are optimized for applications that involve moving huge chunks of data sequentially, like storing vast archives, media libraries, or managing cloud-scale data. This makes them perfect for data centers and enterprise solutions where sheer storage density is paramount.

Powering the Beast: BiCS FLASH Technology

So, how does Kioxia achieve such mind-boggling capacity? The secret lies in its advanced memory technology. The LC9 SSDs utilize 2-terabit (2Tb) QLC NAND dies, specifically Kioxia’s BiCS FLASH generation 8. Let’s break that down simply:

  • NAND: This is the type of flash memory used in SSDs.
  • QLC (Quad-Level Cell): This means each memory cell can store four bits of data. While it might be a bit slower for certain demanding write operations compared to older technologies, QLC is fantastic for cramming more data into less space, making these high capacities possible and generally more cost-effective.
  • 2Tb Dies: These are incredibly dense individual memory chips.
  • BiCS FLASH generation 8: Kioxia’s latest, most efficient manufacturing process for these NAND chips.

To reach that massive 245.76TB, Kioxia stacks these tiny 2Tb dies an impressive 32 high, creating 8TB “packages” of memory. The move to the E3.L form factor over E3.S likely helps accommodate enough of these stacked packages to reach the higher capacities. Interestingly, the standard 2.5-inch form factor also offers a clever advantage: it allows for multiple circuit boards (PCBs) within the 15mm drive height, enabling even greater component density.

A New Era for Data Centers: Density Redefined

The sheer density offered by the Kioxia LC9 is truly transformative for data centers. Consider this: you would need approximately eight of Seagate’s brand-new 30TB 3.5-inch hard drives to match the capacity of just one single 245.76TB Kioxia LC9 SSD, which is significantly smaller at 2.5 inches.

This translates into incredible space savings and efficiency. Imagine a server rack unit (1U) – that’s about 1.75 inches tall – filled with ten of these 2.5-inch Kioxia LC9 drives. You’re looking at nearly 2.5 petabytes (PB) of storage in that tiny space! For context, one petabyte is 1,000 terabytes. Scaling up, a 2U server with 24 bays could house almost 6PB of data. This kind of density fundamentally changes how data centers are built and operated, allowing for more data in less physical footprint and using less power. This massive leap highlights the ongoing shift in enterprise storage, as we’ve previously explored with Seagate’s latest HAMR hard drives.

Final Words

These new 245.76TB Kioxia LC9 NVMe SSDs represent a significant milestone, offering an unprecedented blend of massive capacity and high performance within a remarkably compact design. We’ve seen hints of this at events like FMS 2024, where 122.88TB/128TB drives were making waves, but the rapid doubling of capacity to the 244.76TB/256TB class is truly astonishing.

This trend underscores a key difference between flash storage and traditional hard drives: due to advancements in NAND technology, SSD capacities are roughly doubling every year or two. Hard drive capacities, while still growing, are doing so at a drastically slower rate. These large-capacity SSDs are clearly designed to take over the role of hard drives in the high-capacity storage tiers of data centers. We are now effectively in an era where you only need about four of these incredibly dense Kioxia LC9 drives to store a full petabyte of data. The future of storage is here, and it’s tiny, fast, and capacious.
