The South Korean electronics giant Samsung has recently launched its latest range of high-capacity Solid State Drives (SSD) worldwide. Codenamed PM1633a, this latest 15.36TB storage drive is being claimed as the world’s largest-capacity SSD. It will ensure elevated accuracy and high-geared performance.
The 15.36TB SSD is formed on a 12 GB/s serial attached SCSI (SAS) interface devised specifically for enterprise storage systems and features four times increased storage capacities than the existent memory drives in the market.
The conventional storage drives measure 3.5 inches. The smaller size of PM1633a, 2.5 inches form factor, allows twice the number of usual drives to be stacked in the standard 2U rack of 19 inches.
The gigantic 15.36TB of memory on one SSD has been made possible by an ingenious combination of V-NAND (vertical NAND) chips, each one rated at 256 Gigabits. The sixteen layered 256GB dies have been combined in one 512GB unit. 32 such V-NAND memory units combine together to form one 15.36TB storage drive.
A Big Improvement To Older Chips
The technology had been brought to life by the use of third generation V-NAND based 256GB chips. Constructed in 48 layer cell-arrays, V-NAND chips serve as the basic unit for the PM1633a. whose efficiency and stability in performance has been made possible due to this technology. Previously released PM1633 was constructed using the 32 layered cell-array based 128GB V-NANA chips.
PM1633a is rated at 1 DWPD, which is a measure of the number of drives written per day. The metric serves as a unit of reliability and reflects the better ownership cost for the enterprise storage systems. 1 DWPD refers to the fact that a massive 15.36TB of data can be written onto this memory drive each day. This results in improvement of the cost of ownership because PM1633a can write up to 10x more data as opposed to the typical SATA SSD.
PM1633a also features random read speed of 200,000 IOPS. The write speed of PM1633a can go up to 32,000 IOPS. On the other hand, the sequential read/write speeds of PM1633a can vary up to 1200 Mbps. Thus, PM1633a is 1000x more powerful in terms of the IOPS values than a conventional SATA SSD. PM1633a encompasses a 16GB DRAM. Samsung has also released a customized firmware to access NAND memory in large quantities simultaneously.
Privacy and data protection are the top-most concerns of the modern-day enterprises. Thus, the latest SSD drive by Samsung PM1633a comes with a state-of-the-art metadata protection tool. PM1633a also contains a restoration tool for data recovery.
The Senior Vice President of the Memory Product Planning and Application Engineering Team, Jung-bae Lee expressed the company’s stance in his statement released to the media:
“To satisfy an increasing market need for ultra-high-capacity SAS SSDs from leading enterprise storage system manufacturers, we are directing our best efforts toward meeting our customers’ SSD requests. We will continue to lead the industry with next-generation SSDs, using our advanced 3D V-NAND memory technology, in order to accelerate the growth of the premium memory market while delivering greater performance and efficiency to our customers.”
The storage options in this range will include 48GB, 960GB, 1.92TB, 3.84TB and 7.68TB.
