PCIe Gen 4x4 interface with read speeds up to 3,600MB/s and write speeds up to 2,800MB/s Supports NVMe 1.4 and Host Memory Buffer (HMB) for higher performance and lower latency Supports low density parity check (LDPC) coding to ensure accuracy of data transmission and reliability of data access Supports SLC Caching to improve sequential read/write and random read/write performance Supports RAID to protect data in the case of a drive failure Built-in E2E data protection for enhanced data transfer integrity The UD85 makes it easy to upgrade from PCIe Gen 3 to Gen 4. It's also backwards-compatible with Gen 3 for greater flexibility across systems. And, its M.2 2280 size easily integrates into designs with M.2 connectors, making it the perfect choice for thin laptops and small form factor PCs.
