Union Memory has introduced the UM301a, an M.2 80 form factor solid-state drive (SSD) that operates without DRAM, explicitly tailored for enterprise-level applications. This cutting-edge product utilizes a PCIe Gen4 ×4 interface and adheres to the NVMe 1.4b protocol, presenting users with three distinct capacity choices: 480GB, 960GB, and 1.92TB. Across the entire product lineup, sequential read speeds can soar up to 5000MB/s. Specifically, the 1.92TB variant achieves sequential write speeds of 2500MB/s, 4KB random read speeds of 350K IOPS, and random write speeds of 12K IOPS. When it comes to latency, the entire series maintains an average sequential read/write latency of 20μs, an average random read latency of 110μs, and a random write latency of 100μs. Moreover, the drive's endurance is remarkable, reaching 0.5 DWPD (Drive Writes Per Day) or 912.5 TBW/TB (Total Bytes Written per Terabyte).
A standout feature of the UM301a is its DRAM-less design. This innovative approach effectively mitigates the risk of system downtime stemming from unrecoverable DDR errors. Additionally, the drive boasts an impressive mean time between failures (MTBF) of up to 2 million hours and maintains an uncorrectable bit error rate (UBER) of less than 1E-17, ensuring exceptional reliability and data integrity.
