On Friday Samsung announced
the PM1733 PCIe Gen4 Solid State Drive (SSD), an enterprise-class drive that offers “the highest performance of any SSD on the market today.” Built using Gen5 512Gb TLC V-NAND, the PM1733 will be available in both U.2 (Gen 4 x4) and HHHL (Gen 4 x8) forming factors with a maximum capacity of 30.72 TB and 15.36 TB, respectively. It is backward compatible with the older PCIe 3.0 interface but will significantly impede performance by using it on that platform.
The device reads at 8.0GB/s sequentially and at 1,500,000 IOPS randomly. Additional specs have not yet been disclosed, although Samsung has said that it has double the present Gen 3 SSDs throughput capabilities.
