🧰 Samsung M.2 NVMe 256 GB – Overview
Form Factor: M.2 2280 (22 mm × 80 mm)
Interface: NVMe PCIe Gen3 x4 (some newer models use Gen4)
Capacity: 256 GB
Controller: Samsung in-house controller (varies by model)
NAND Type: Samsung V-NAND (3D NAND)
Sequential Read/Write Speeds:
Read: ~2000–3500 MB/s depending on model
Write: ~1000–3000 MB/s depending on model
Random IOPS: Up to ~300K reads / ~300K writes
Form Factor: M.2 2280 (fits most modern motherboards)
🔧 Key Features
High-Speed Performance
NVMe over PCIe interface gives much faster read/write than SATA SSDs.
Ideal for OS drive, boot drive, gaming, and apps.
Durability & Reliability
Samsung M.2 NVMe SSDs are highly reliable with good endurance ratings.
TBW (Terabytes Written) ~150–200 TB for 256 GB models.
Low Power Consumption
Efficient operation compared to SATA SSDs, especially useful for laptops.
Samsung Ecosystem
Compatible with Samsung Magician software for firmware updates, optimization, and health monitoring.
🖥️ Compatibility
Motherboards: Any motherboard with M.2 slot supporting NVMe PCIe (PCIe 3.0 or 4.0)
Operating Systems: Windows 7/8/10/11, Linux, macOS (if supported by NVMe driver)
Form Factor Check: Ensure M.2 2280 slot; some boards may have M key vs B key differences (most NVMe drives are M key).
💡 Use Cases
Boot Drive / OS Drive – Enjoy very fast startup and load times.
Gaming – Reduce game load times significantly.
Content Creation / Productivity – Get high-speed access to project files, video editing, etc.
⚠️ Notes
M.2 NVMe is not compatible with M.2 SATA slots; NVMe requires PCIe lanes.
For full speed, connect to PCIe 3.0 x4 or PCIe 4.0 x4 slot depending on SSD model.
256 GB is enough for OS and a few games/apps; for large game libraries, 500 GB or 1 TB may be preferable.
