  • Kioxia Launches First 245.76 TB NVMe SSD for AI Workloads

    Kioxia Launches First 245.76 TB NVMe SSD for AI Workloads

    Key Takeaways

    1. Kioxia has launched the LC9 Series NVMe SSD with a capacity of 245.76 TB, the highest available for both 2.5-inch and EDSFF E3.L formats.
    2. The new SSD doubles the previous maximum capacity of 122.88 TB, catering to data centers with high space efficiency needs.
    3. The drive supports demanding applications like generative AI and vector databases by reducing I/O bottlenecks during data processing.
    4. It features advanced technology with 32 BiCS FLASH QLC dies and a PCIe 5.0 x4 NVMe 2.0 controller, offering fast speeds of up to 12 GB/s for reads.
    5. The drive includes reliability features like die-level recovery and power-loss protection, achieving around 1.3 million IOPS for reads and 50,000 IOPS for writes.

    Kioxia has introduced a new model with a capacity of 245.76 TB in its LC9 Series, making it the highest-capacity NVMe SSD available in both 2.5-inch and EDSFF E3.L formats. This new version doubles the previous maximum capacity of 122.88 TB in the series and is designed for data centers where space efficiency is crucial.

    Demand for High-Capacity Storage

    The needs of generative AI training, vector databases, and various retrieval-augmented generation tasks require large, efficient, and speedy storage solutions. Kioxia emphasizes that the LC9’s large scale is meant to alleviate I/O bottlenecks, which can cause costly GPUs to sit idle during data ingestion and inference processes.

    Advanced Technology and Performance

    This drive utilizes 32 of Kioxia’s 2 Tbit BiCS FLASH QLC dies, employing CMOS-direct-bonded-to-array (CBA) technology that allows for 8 TB in a single NAND package, marking another industry milestone. It features a PCIe 5.0 x4 (dual-port) NVMe 2.0 controller that offers up to 12 GB/s for sequential reads and 3 GB/s for writes, effectively balancing signal integrity with the high package density and extreme height.

    Specifications and Reliability

    In terms of random throughput, the drive achieves around 1.3 million IOPS for reads and 50,000 IOPS for writes, with an endurance rating of 0.3 DWPD suitable for typical hyperscale workloads. To ensure reliability, it includes die-level recovery, parity-based error management, and power-loss protection, in addition to Flexible Data Placement that helps minimize write amplification.

    Kioxia is currently sampling the 245 TB LC9 to selected partners, with larger volume units to be available in 2.5-inch U.2 (up to 122.88 TB), E3.S (up to 122.88 TB), and E3.L (245.76 TB) formats. A public demonstration is scheduled for the Future of Memory and Storage conference in August 2025.

  • Samsung 9100 Pro PCIe 5.0 SSDs Offer 14,800 MB/s Read Speeds

    Samsung 9100 Pro PCIe 5.0 SSDs Offer 14,800 MB/s Read Speeds

    Key Takeaways

    1. Samsung’s new PCIe 5.0 M.2 NVMe SSDs can achieve read speeds of up to 14,800 MB/s.
    2. Available sizes include 1TB, 2TB, 4TB, with an 8TB version expected later this year.
    3. The SSDs come in both heatsink and non-heatsink versions, maintaining the 2280 form factor.
    4. All models are backed by a five-year limited warranty and adhere to advanced data encryption standards.
    5. Pricing starts at $200 for the 1TB model and goes up to $570 for the 4TB heatsink version.

    Samsung has just revealed its super speedy PCIe 5.0 M.2 NVMe SSDs, which can achieve read speeds of up to 14,800 MB/s. You can now order the 9100 Pro and the 9100 Pro with Heatsink directly from Samsung’s website or from a few chosen retailers. These SSDs come in 1TB, 2TB, and 4TB sizes. Samsung also announced that they will release 8TB versions in the second half of this year. While these SSDs redefine the capabilities of PCIe 5.0, they do come at a higher price.

    Product Specifications

    Utilizing the PCIe 5.0 x4 interface, the 9100 Pro series maintains the 2280 form factor and offers both Heatsink and non-heatsink versions. Storage options include 1TB, 2TB, 4TB, and the upcoming 8TB (expected later this year), with comparable read and write speeds across the variants. The 4TB and 8TB options can achieve the maximum advertised sequential read speed of 14,800 MB/s and sequential write speeds of 13,400 MB/s. Meanwhile, the 1TB and 2TB models are slightly slower, reaching 14,700 MB/s for sequential reads, with the 1TB variant having the lowest sequential write speeds at 13,300 MB/s.

    Durability and Warranty

    All variants are equipped with Samsung’s V NAND TLC (V8) and come with a custom controller. Regarding durability, the 1TB model is rated for 600 TBW (Total Bytes Written), the 2TB version for 1,200, the 4TB for 2,400, and the 8TB for 4,800. Each model is backed by Samsung’s five-year limited warranty, which is typical for most Samsung SSDs. They also adhere to Class 0 (AES 256), TCG/Opal v2.0, and MS eDrive (IEEE1667) data encryption standards to keep your data secure.

    Pricing Information

    The pricing for the 1TB 9100 Pro SSD is set at $200, while the heatsink version costs $220. For the 2TB model, the price is $300 without the heatsink and $320 with it. The 4TB variant is priced at $550 for the non-heatsink version and $570 for the heatsink version. You can find all of these products available on Samsung’s online store, Amazon, Newegg, and Best Buy.
