Product Features

Extreme NVMe Performance

The SSD leverages PCIe Gen 3.0 x4 interface and NVMe 1.3 protocol, achieving sequential read speeds up to 3,300 MB/s and write speeds up to 1,200 MB/s (depending on system configuration). This ensures lightning-fast boot times, application launches, and high-speed file transfers.

High-Quality 3D TLC NAND Flash

Equipped with wafer-level 3D TLC NAND, this drive provides superior endurance, reliability, and consistent performance over its lifespan, suitable for heavy workloads.

SLC Cache for Burst Performance

Integrated “Max. Write” SLC caching technology enhances write performance during large or sequential data transfers, maintaining high speeds even under sustained loads.

Data Reliability and Longevity

Supports LDPC ECC (Low-Density Parity-Check Error Correction) and advanced wear leveling to improve data integrity, prevent errors, and prolong NAND life.

Intelligent Drive Management

Includes support for S.M.A.R.T. monitoring, TRIM optimization, and automatic Garbage Collection to maintain performance, manage data efficiently, and extend drive lifespan.

Durable and Compact Design

The M.2 2280 form factor, low weight (8 g), and solid-state construction ensure shock resistance, silent operation, and compatibility with ultrabooks, desktops, and mini-PCs. Advanced thermal management prevents overheating during heavy workloads.

Energy-Efficient Operation

Designed with low power consumption (0.17 W idle, 2.8 W max), making it efficient for portable systems while reducing heat generation in desktops.
