Kioxia recently announced a new solid-state drive with the largest capacity to date, 245.76 TB.
LC9 drive characteristics
The new LC9 drive is designed for hyperscale workloads and AI model data storage. A total of 8 TB of cells were placed on a single NAND chip, which is considered the highest density at this stage.
It is also known that a new controller is used in the SSD. The case of the new product corresponds to the form factor of E3.L data center drives.
The sequential data read speed will be within 12 GB/s, and the write speed will be 3 GB/s. These figures are impressive for a device with such a number of chips and a high load on the controller. Random operations can be performed at a speed of 50,000 IOPS (write) and 1.3 million IOPS (read).
As for the specific features of the technology, there is paired error control, kernel-level recovery, and power loss protection. In addition, post-quantum cryptography algorithms, CNSA 2.0 firmware digital signature, and AES-256 encryption are supported.
The release is planned in several form factors:
- E3.L — up to 245.76 TB.
- E3.S — up to 122.88 TB.
- U.2 — up to 122.88 TB.
At this stage, there is no information on pricing, and the official product presentation will take place at Future of Memory and Storage in August of this year.
