Capable of delivering industry-best sub-1 millisecond latency on the taxing RocksDB workload, the 7600 SSD is ideal for workloads where response time is critical. The 7600 SSD provides the right balance of affordability, performance and predictable latency for most data center workloads including AI.
- With best-in-class sequential reads of 12 GB/s, the 7600 SSD outperforms competitive mainstream SSDs, with up to:
- 27% better sequential writes with 7 GB/s
- 5% better random reads with 2.1 MIOPS
- 100% better random writes with 400 KIOPS
- Unrivaled RocksDB workload performance and energy efficiency compared to competitive Gen5 SSDs, as follows:7
Random read | Random read while writing | |
Maximum performance | Up to 21% higher | Up to 23% higher |
99thpercentile latency | Up to 59% better | Up to 76% better |
Energy efficiency | Up to 78% better | Up to 79% better |
“At CoreWeave, we're relentlessly focused on pushing the boundaries of performance and helping our customers maximize their infrastructure efficiency,” said
Micron's vertical integration ensures that each of these SSDs is designed and manufactured with a Micron controller, G9 NAND, DRAM, firmware and manufacturing processes. This integration helps provide exceptional quality and a more reliable, secure supply chain. Additionally, key security features — including hardware root of trust, SPDM 1.2 (attestation) for identity authentication and firmware verification, CNSA 2.0 dual signed PKI/LMS firmware binary, self-encrypting drive (SED) and Micron Secure Execution Environment8 — help secure data. OCP 2.6 support is available for the Micron 9650 and 6600 ION SSDs, and the 7600 SSD utilizes OCP 2.5 support.9
