A Kioxia announced a new 245 tb SSDthe largest in the world so far, with sufficient capacity to store up to 12,500 movies in 4K. The launch represents a significant leap in density and performance in the storage segment for date centers.
SSD is part of Kioxia’s LC9 line and uses BICS8 memory technology with QLC (quad-level cell) cells. This combination allows you to reach up to 2 tb per chip, with package 32 dies package, totaling 8 tb per unit stacked.

Formats and connections focused on data centers
The model of 245.76 tb is offered in E3.L formatfocused on large -scale corporate applications. There are also smaller versions, such as E3.S up to 122.88 tb, both with PCIE Gen 5.0 x4 connection and NVME 2.0 standard support. This advance reinforces the trend of massive storage devices, such as SSDs E2 with capacity of up to 1 petabyte.
Performance for heavy reading loads
Kioxia SSD reaches sequential reading speeds up to 12 GB/if written up to 3 GB/s. In random operations, there are about 1.3 million reading IOPs and 50,000 writing.
According to the company, this performance is ideal for intensive reading applications, such as training artificial intelligence models, vector databases and data lakes. Density also contributes to reducing the total cost of large -scale infrastructure property.
Durability within the standard for QLC
Despite the impressive capacity, durability follows the expected patterns for QLC chips, with a resistance of 0.3 DWPD (Drive Write Per Day). This is equivalent to approximately 67 petabytes of data recorded in five years in the most capacity model.
Advanced security and encryption
LC9 offers safety resources such as AES-256 encryption, energy loss protection and post-quantic encryption support. The controller also ensures robust error correction and dual-port support, making it ideal for sensitive environments.
This type of protection refers to solutions such as SSD with Team Group’s self -destruction circuit, aimed at extreme security contexts.
Thermal and energy efficiency
Kioxia highlighted the thermal optimization of LC9, which allows greater rack density, with lower power consumption and less need for refrigeration. This factor is decisive in modern data centers, where the balance between performance and consumption is essential.
