Samsung Electronics, the world leader in advanced memory technology, announced on March 3 that it will release the world’s largest 15.36 terabyte (TB) solid state drive (SSD), which is based on a Serial Attached SCSI (SAS) interface. It has four times larger storage capacities than existing products. The 15.36TB SSD has the largest storage capacity among single storage devices, including hard disk drive (HDD).
The unprecedented 15.36TB of data storage on a single SSD is enabled by combining 512 of Samsung’s third-generation, 256-gigabit (Gb) V-NAND memory chips. The 256Gb dies are stacked in 16 layers to form a single 512GB package. For the SSD, 32 512GB packages and about 550 memory chips, including 16GB DRAM, are mounted on both sides of two printed circuit boards (PCB). It is like memory chips for seven high performance laptops (2TB SSD and 8GB DRAM) are used on a 2.5-inch storage device.
The latest SSD is based on a SAS interface, which is used for server and storage, and can create two times faster SSD than the one based on a Serial ATA (SATA) interface, which is usually used in personal computers. Moreover, the SSD sports random read and write speeds of up to 200,000 and 32,000 IOPS respectively, and delivers sequential read and write speeds of up to 1,200MB/s, which is more than twice the speed of a typical SATA SSD, through Samsung’s advanced controller units and specially designed firmware that can access large amounts of high-density NAND flash concurrently.
In addition, it has two to ten times higher durability than a typical SATA SSD with 10 nano-class 128Gb NAND flash memories. Further, the drive boasts a highly dependable metadata protection mechanism in addition to featuring a data protection and restoration software tool in case of a momentary blackout, providing software solutions that improves the convenience and safety of customers’ system maintenance.
