KIOXIA has launched a solid-state drive that appears like one thing out of a science fiction novel: the LC9 Sequence, with a whopping 245.76TB of storage—sufficient to carry round 12,500 4K films at 20GB every.
Out there in capacities from 30.72TB to 245.76TB, the LC9 is available in 2.5-inch U.2, E3.S, and E3.L type components. These aren’t for client PCs however are constructed for enterprise the place area effectivity and knowledge density matter. Kioxia achieves this with its eighth-generation BiCS FLASH QLC NAND, stacking 32 reminiscence dies—every with 2 terabits—into an 8TB bundle. That is due to CMOS Bonded to Array (CBA) know-how, which bonds the NAND’s management circuitry to the reminiscence array on the wafer stage. The result’s an 11.5 by 13.5 millimeter bundle that maximizes knowledge density whereas conserving sign paths brief for efficiency.

The LC9 has sequential learn speeds of as much as 12GB/s and write speeds of 3GB/s, with random learn efficiency of 1.3 million IOPS. Client SSDs just like the Samsung 990 Professional high out at round 7.5GB/s for reads, so the LC9 is a beast for demanding environments. Its write endurance is rated at 0.3 drive writes per day (DWPD), which is about 67,000TB written over 5 years for the 245TB mannequin—good for read-intensive workloads like AI coaching or knowledge lakes. Twin-port connectivity provides redundancy for important techniques.
Safety and sturdiness are key to the LC9’s design for industries the place knowledge integrity is paramount. It has energy loss safety and end-to-end knowledge safety to guard in opposition to knowledge corruption throughout transfers or sudden shutdowns. For delicate knowledge, KIOXIA consists of Sanitize Prompt Erase (SIE), Self-Encrypting Drive (SED) and plans for FIPS 140-3 compliance with AES-256 encryption. The drive additionally helps the Leighton-Micali Signature algorithm, assembly authorities and enterprise safety requirements.
The LC9’s magic is in its large capability and sensible engineering. It makes use of a PCIe 5.0 x4 interface with NVMe 2.0 compliance so it really works with fashionable knowledge heart {hardware}. It’s additionally aligned with the Open Compute Mission’s Datacenter NVMe SSD specification, model 2.5, for simple integration into standardized, scalable techniques. Kioxia’s customized controller and firmware is optimized for hyperscale environments.
Pricing shouldn’t be disclosed as KIOXIA is working with knowledge heart clients on customized quotes based mostly on quantity. Sampling is underway with choose companions and a showcase is deliberate for the Way forward for Reminiscence and Storage convention in August 2025.
