Longsys has unveiled the WM8500, a 5nm Storage Processing Unit designed to reduce costs and increase capacity by providing up to 2:1 lossless data compression for enterprise SSDs.

Key Points

• The WM8500 is a DRAM-less ASIC that utilizes a High Level Cache and an intelligent Storage Agent to manage data compression.
• The chip supports single-drive capacities of up to 128TB, significantly exceeding the 8TB limit found in most mainstream consumer SSDs.
• Longsys claims the technology reduces DRAM requirements by 40%, offering a cost-effective alternative to traditional hard disk drives in data centers.
• The hardware is specifically optimized for AI workloads, though compression ratios may vary depending on data encryption or obfuscation levels.

Why it Matters

This technology addresses the rising costs of NAND flash by allowing data centers to maximize storage density through hardware-based compression. By lowering DRAM dependency, the WM8500 provides a scalable solution for AI-driven infrastructure that requires massive, cost-efficient storage capacity.
