SSD Lenovo Liteon CL1 256GB M.2 PCIe NVMe Gen3 x4 (5SS0Z21492)

Get up to 1800 MB/s sequential reads from this 256GB M.2 2280 NVMe SSD. The Liteon CL1 pairs a Phison PS5008-E8 controller with 3D TLC NAND to deliver 120,000 random read IOPS and 100,000 random write IOPS, all in a compact card designed for Lenovo systems.

Overview

The Lenovo SSD Liteon CL1 256G M.2 PCIe (5SS0Z21492) is a high-performance solid-state drive built around the PCIe Gen3 x4 NVMe 1.3 interface. Its M.2 2280 form factor fits directly into compatible Lenovo laptops and desktops, replacing slower SATA drives with a significant speed boost. The drive uses 3D TLC NAND flash, which offers a good balance of performance, endurance, and cost. With a mean time between failures (MTBF) of 1,500,000 hours and an endurance rating of 100 TBW, it is built for reliable everyday use.

What stands out

• Sequential read speed up to 1800 MB/s – nearly 3x faster than typical SATA SSDs.
• Sequential write speed up to 1000 MB/s – quick file transfers and application loads.
• Random read IOPS up to 120,000 and random write IOPS up to 100,000 – responsive multitasking.
• NVMe 1.3 protocol over PCIe Gen3 x4 – low latency and high throughput.
• M.2 2280 form factor – easy installation in compatible Lenovo systems.
• Power-efficient: only 3.5 W active read/write and 0.05 W idle.
