Nextron M22561 256GB M.2 NVME Gen3 Solid State Drive ( SSD )

The Nextron M22561 is a 256 GB M.2 2280 internal solid-state drive built on the PCIe 3.0 x4 NVMe interface. It is designed for users who want to move beyond legacy SATA storage without paying a premium, making it a practical upgrade for laptops, compact desktops, and small-form-factor systems. At the heart of the M22561 is the Silicon Motion SM2263XT controller. This is a DRAM-less architecture that leverages Host Memory Buffer (HMB) technology, allowing the drive to borrow a portion of system RAM as a cache buffer. The result is a cost-efficient design that still delivers meaningful NVMe performance suitable for everyday computing, light creative work, and general productivity. The drive uses 3D NAND flash memory, which stacks memory cells vertically to improve density and endurance compared to planar NAND. Data integrity is maintained through 4K LDPC (Low-Density Parity-Check) ECC error correction and end-to-end data path protection, reducing the likelihood of silent data corruption during read and write operations. S.M.A.R.T. monitoring support allows compatible systems and utilities to track drive health over time. Physically, the M22561 measures 8 × 2.2 × 0.4 cm and weighs approximately 20 g. Its single-sided PCB design keeps the thickness at 2.7 mm, which is compatible with slim notebooks and ultrabooks that have tight clearances around the M.2 slot. The drive is compatible with most Intel and AMD platform chipsets that expose a PCIe 3.0 x4 M.2 slot. Manufactured by Nextron Technologies LLP in India, the M22561 is sold with a stated 5-year limited warranty.
