Samsung said that this hard drive is developed for the next generation of enterprise storage systems. It uses Samsung's latest V-NAND technology, which combines 32 1TB NAND Flash memories; and each NAND Flash memory uses 16 V-NAND chip stacks. As a result, this hard drive can store 5,700 5GB high-definition movies, and its size is only 2.5 inches. In addition to the increase in capacity, the transmission performance of PM1643 has also been significantly improved, which is almost twice that of Samsung's previous generation of super-capacity SAS solid-state drives. Based on the 12Gb/s SAS interface, the random read speed and write speed of the PM1643 disk have reached 40000 IOPS and 50000 IOPS respectively, and the continuous read speed reached 2100MB/s and 1700 MB/s; the random read performance is the traditional 2.5-inch SATA 4 times of SSD, and continuous read performance is 3 times of the former. In order to achieve the above results, Samsung has made efforts in the design of...
