 Upgrade Your Productivity

Upgrade Your Productivity

Looking to make the switch to the latest generation of PCIe interface? The UD85 is the perfect introduction to the power of PCIe 4.0. With support for NVMe 1.4 and Host Memory Buffer (HMB) technology, you'll get uninterrupted productivity via higher performance and lower latency for seamless execution across applications.

 Speed Up Your Efficiency

Speed Up Your Efficiency

The UD85 delivers a fast and smooth experience with read speeds up to 3,600MB/s and write speeds up to 2,800MB/s. It achieves improved sequential read/write and random read/write performance with support for SLC Caching.

 Do More With 4TB For Less

Do More With 4TB For Less

The UD85 is all about value: it's available in large storage capacities up to 4TB with an affordable price tag. Get all the space you need for applications, documents, photos, and videos without breaking the bank.

 A Flexible Upgrade

A Flexible Upgrade

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.

 Lower Latency With 3D NAND

Lower Latency With 3D NAND

With 3D NAND flash technology, the UD85 incorporates multiple layers of vertically-stacked memory cells to overcome the density limitations of its single-layered 2D counterpart and achieve greater capacities. A reduced distance between memory cells also results in lower latency and higher performance.

 Comprehensive Data Protection And Accuracy

Comprehensive Data Protection And Accuracy

The UD85 supports low density parity check (LDPC) coding to ensure accuracy of data transmission and reliability of data access, while RAID protects data in the case of a drive failure. It's also equipped with built-in E2E data protection and an automatic error correction code (ECC) function for enhanced data transfer integrity.
