Key Features
- [IMPORTANT COMPATIBILITY] M.2 SATA III ONLY This SSD is an M.2 SATA III 6Gb/s drive featuring a B+M Key. It is designed strictly for M.2 slots that support the SATA protocol. Please Note: This drive is NOT compatible with NVMe or PCIe slots. Please verify your device specifications before purchase to ensure compatibility.

- [ADVANCED DURABILITY] 3D TLC NAND & LDPC Built with high-quality 3D TLC NAND flash and a total bytes written (TBW) rating of 70TB. It utilizes a RAID engine and LDPC (Low-Density Parity Check) error correction to ensure data integrity, superior stability, and a prolonged lifespan for your critical data.
- [EFFICIENCY] DEVSLEEP & SMART SUPPORT Supports SATA Device Sleep (DevSleep) mode, which conserves battery life by intelligently powering down the SSD when not in use while maintaining instant wake-up response.
