Lenovo SSD 512GB M.2 PCIe 2242 NVMe Gen3 x4 solid state drive (5SS0V42255)

Built for systems that demand high-speed storage in a compact footprint, the Lenovo 5SS0V42255 delivers 512GB of NVMe performance in an M.2 2242 form factor. Unlike standard 2.5-inch SATA drives, this PCIe Gen3 x4 SSD uses a direct PCIe connection to slash load times and accelerate data-intensive tasks, making it a smart upgrade for ultrabooks, mini PCs, and embedded systems where space is at a premium.

Highlights

• 512GB capacity with 3D TLC NAND for a balance of performance and endurance
• PCIe Gen3 x4 interface with NVMe 1.3 support for sequential reads up to 3300 MB/s
• Compact M.2 2242 form factor (22mm x 42mm) fits slim devices and small-form-factor builds
• Host Memory Buffer (HMB) technology reduces cost and power without sacrificing speed
• Endurance rated at 300 TBW with 1.5 million hours MTBF for long-term reliability

In daily use

Boot your operating system in seconds, launch applications instantly, and transfer large files without waiting. The drive's low power consumption (under 5W active, under 0.1W idle) helps extend battery life in portable devices, while TRIM and S.M.A.R.T. support keep performance consistent over time. With an operating temperature range of 0°C to 70°C and shock resistance up to 1500G, it handles the bumps and thermal stress of mobile computing with ease.
