Lenovo 512GB M.2 2242 PCIe Gen3 x4 NVMe SSD (5SS0W79485)

Unlike standard 2.5-inch SATA drives, this Lenovo 512GB M.2 2242 SSD leverages PCIe Gen3 x4 and NVMe 1.3 to deliver up to 3500 MB/s sequential reads and 2700 MB/s writes, dramatically reducing boot times and application load. Its compact 2242 form factor fits ultra-thin laptops and small-form-factor desktops where space is at a premium, while the 3D TLC NAND ensures a balance of performance, endurance, and value. With hardware-based AES 256-bit encryption (when supported by the host system), it safeguards sensitive data without compromising speed.

Highlights

• 512 GB capacity with 3D TLC NAND for reliable everyday storage
• PCIe Gen3 x4 interface and NVMe 1.3 protocol for high throughput
• M.2 2242 form factor for compatibility with slim devices
• Sequential read up to 3500 MB/s, write up to 2700 MB/s
• Endurance rated at 150 TBW and MTBF of 1.5 million hours
• Hardware-based AES 256-bit encryption support

In daily use

This SSD transforms system responsiveness: boot your OS in seconds, launch heavy applications without lag, and transfer large files quickly. Its low power consumption (3-5 W active, 0.05 W idle) helps extend battery life in laptops, while the wide operating temperature range (0°C to 70°C) ensures stable performance under load. The drive is engineered to withstand shocks up to 1500G and vibration up to 20G, making it suitable for mobile workstations and rugged environments.
