1. Samsung has introduced a 61.44 TB SSD, the BM1743, using 7th generation V-NAND QLC memory. 2. The company plans to offer the drive in U.2 and E3.S form factors for PCIe 4.0 and 5.0 respectively. 3. Samsung envisions future drives reaching up to 120 TB capacity based on the same technology.

1. Kioxia is sampling 2 terabit NAND chips with a QLC design and BiCS 8 218-layer architecture. 2. The new chip offers higher bit density and power efficiency compared to previous generations. 3. Pure Storage plans to use these chips to enhance their all-flash storage solutions.

➀ Samsung has started mass production of its new V9 QLC V-NAND; ➁ The technology enables larger SSDs with features like channel hole etching for higher layer counts; ➂ Improved data retention performance and reduced power consumption are noted.

➀ Samsung has begun mass production of a 286-layer QLC NAND; ➁ The new NAND is aimed at the server market with a density of 28.5 Gb/mm²; ➂ It offers improved performance compared to the previous generation.

➀ The Samsung BM1743, a 128TB NVMe SSD, was showcased at the Future of Memory and Storage 2024 event, revealing its internal structure. ➁ The SSD features dual PCBs with a large number of NAND and DRAM chips, indicating high storage density. ➂ Samsung uses QLC technology in the BM1743, with reported 45K Random Write IOPS at 16KB, shifting from typical 4K benchmarks.

❶ The 4TB WD Blue SN5000, based on QLC technology, offers competitive performance with single-sided design suitable for various devices. ❷ It features BiCS6 QLC flash, promising efficiency and high data density, though it may lag slightly in write performance compared to TLC. ❸ Pricing and optimal utilization of its PCIe 4.0 interface remain concerns, but it presents a viable option for mainstream users if competitively priced.
