Samsung Shows Off its Biggest and Fastest SSDs at FMS 2015
 

At the 2015 Flash Memory Summit, Samsung announced the fruition of its swanky new 48-layer 3D V-NAND chips, the PM1633a. Built in the 2.5-inch form-factor, and featuring a SAS 12 Gb/s interface, this drive offers an unformatted capacity nearing 16 TB (15,360 GB to be precise). The drive relies on ten 48-layer stacks of 256 Gb 3-bit NAND flash dies, making up 15,360 GB of unformatted capacity. Samsung showed off a system with 48 of these drives, making up 720 TB of total storage.

Besides the largest SSD, Samsung also showed off the fastest. The PM1725 SSD, designed for servers with high-traffic databases, where throughput is the king, is built in the 2.5-inch form factor (up to 3.2 TB) and HHHL form-factor (up to 6.4 TB). It features a PCI-Express 3.0 host bus, and talks to the OS over the modern NVMe protocol. The two offer random access throughput of up to 1,000,000 IOPS.
