Union Memory launches UH711a SSD for the data center market
Union Memory recently launched the UH711a PCIe 4.0 SSD. Union Memory claims that the UH711a can provide high-performance, low-latency, and high-reliability solutions for the data center market.
The solid-state drive supports PCIe 4.0 x4 and NVMe 1.4 protocols. The NAND flash memory is 3D TLC. The size is 2.5 inches and the weight is less than 350g. There are three capacity versions, 1.92TB, 3.84TB, and 7.68TB.
In terms of speed, the maximum sequential read speed of the three versions is 7200MB/s, and the maximum sequential write speed is somewhat different, among which the maximum sequential write speed of the 1.92TB version is 2600MB/s; the maximum sequential write speed of the 3.84TB version is 4500MB/s; the maximum sequential write speed of the 7.68TB version is 4600MB/s.
The DWPD of the three versions is 1, the average trouble-free working time is 2 million hours, and the total data written volume is 3.5PB, 7.01PB, and 14.02PB respectively. When the hard disk is working, the maximum power consumption can reach 21W, which is much higher than that of the home M.2 hard disk.
UH711a supports features such as variable sectors, intelligent multi-flow, QoS, etc., and adopts a dynamic and static wear balance algorithm, which is officially claimed to be able to effectively extend the life of the hard disk. A dual firmware backup upgrade mechanism and power failure protection mechanisms can also reduce the risk of data loss.
Unlike the common M.2 interface of ordinary consumer hard drives, this hard drive uses a U.2 interface.
