PCIe PM971-NVMe SSSD by Samsung in Production

128GB, 256 and 512GB, in single ball grid array

Samsung Electronics Co., Ltd. has begun mass producing the industry’s first NVMe (*) PCIe SSD in a single ball grid array (BGA) package, for use in next-generation PCs and ultra-slim notebook PCs.

The BGA NVMe SSD, named PM971-NVMe, features an compact package that contains all essential SSD components including NAND flash memory, DRAM and controller while delivering outstanding performance.

The company rolls out first NVMe SSD in ultra-small BGA package design.

Samsung’s new BGA NVMe SSD triples the performance of a typical SATA SSD, in the smallest form factor available, with storage capacity reaching up to 512GB,” said Jung-bae Lee, SVP, memory product planning and application engineering team, Samsung. “The introduction of this small-scale SSD will help global PC companies to make timely launches of slimmer, more stylish computing devices, while offering consumers a more satisfactory computing environment.

Configuring the PM971-NVMe SSD in a single BGA package was enabled by combining 16 of firm’s 48-layer 256-gigabit V-NAND flash chips, one 20-nanometer 4Gb LPDDR4 mobile DRAM chip and a performance company’s controller. This SSD is 20x16x1.5mm and weighs only about one gram (an American dime by comparison weighs 2.3 grams). The single-package SSD’s volume is approximately a hundredth of a 2.5″ SSD or HDD, and its surface area is about a fifth of an M.2 SSD, allowing much more design flexibility for computing device manufacturers.

In addition, the PM971-NVMe SSD delivers a level of performance that easily surpasses the speed limit of a SATA 6Gb/s interface. It enables sequential read and write speeds of up to 1,500MB/s and 900MB/s respectively, when TurboWrite (**) technology is used. The performance figures can be directly compared to transferring a 5GB-equivalent, Full-HD movie in about 3s or downloading it in about 6s. It also boasts random read and write IO/s (input output operations per second) of up to 190,000 and 150,000 respectively, to easily handle high-speed operations. A HDD, by contrast, will only process up to 120 IO/s in random reads, making the new company’s SSD more than 1,500 times faster than an HDD in this regard.

The PM971-NVMe SSD line-up will be available in 512, 256 and 128GB storage options. The company will start providing this SSDs to its customers this month worldwide.

As a SSD provider, the company has a history of introducing advanced SSDs ahead of the industry. In June 2013, the firm introduced XP941 SSD in M.2 (mini PCIe 2.0) form factor (80x22mm), which was also the industry’s first PCIe SSD for PCs. Now, the company plans to rapidly expand its market base in the next-generation premium notebook PC sector with the new high-performance, BGA package, NVMe SSD.

Later this year, the firm plans to introduce more high-capacity and ultra-fast NVMe SSDs to meet increasing customer needs for improved performance and greater density.

(*) Often shortened as NVMe (Non-Volatile Memory Express) is an optimized, high performance, scalable host controller interface with a streamlined register interface and command set designed for enterprise, datacenter and client systems that use non-volatile memory storage. For more information.
(**) TurboWrite is a company’s proprietary technology that temporarily uses certain portions of an SSD as a write buffer. TurboWrite delivers better PC experiences as users can enjoy much faster sequential write speeds.
