Micron has unveiled its 7500-series SSDs, integrating the advanced 232-layer 3D TLC NAND technology. While these SSDs maintain the PCIe Gen4 interface, their performance surpasses the preceding 7450-series. Primarily, they cater to an array of data center storage needs, from cloud to enterprise servers.
Although the 7500-series SSDs incorporate the controller and platform similar to the 7450-series, they are distinct and not mere rebrands. Significant enhancements include updated firmware and varied memory setups. Consequently, the 7500-series SSDs manifest a sub-1 ms Quality-of-Service (QoS) latency, augmented sequential and random read/write performance, and diminished latencies.
Performance metrics for these SSDs reveal maximum sequential read speeds reaching 7,000 MB/s and sequential write speeds touching 5,900 MB/s, outdoing the 7450-series marginally. Their random performance stands at approximately 1.1 million random read IOPS and 400 thousand random write IOPS, comparable to elite consumer SSDs. Notably, latency optimization was prioritized, making these SSDs especially adept for RocksDB applications.
Shifting from the 7450-series, Micron's 7500 SSDs target mainstream NVMe data center applications, exclusively produced in U.3/U.2/15mm form-factors, prevalent in the server drive industry. They provide a broad capacity spectrum, spanning from 800GB to a noteworthy 15.36TB.
Moreover, Micron will persist in offering the 7500 Pro drives optimized for capacity, with a pinnacle of 15.36TB and a daily write frequency (DWPD) of 1. They also present the endurance-centric mixed-use 7500 Max SSDs, boasting a 3 DWPD rating.
