Samsung today announced that it has begun mass producing the NVMe PCIe solid state drive (SSD) in a single ball grid array (BGA) package. This new SSD is 20mm x 16mm x 1.5mm and weighs only about one gram. 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. This new SSD will allow much more design flexibility for computing device manufacturers for use in their next-generation PCs and ultra-slim notebook PCs.
Configuring the PM971-NVMe SSD in a single BGA package was enabled by combining 16 of Samsung's 48-layer 256-gigabit (Gb) V-NAND flash chips, one 20-nanometer 4Gb LPDDR4 mobile DRAM chip and a high-performance Samsung controller.
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 (megabytes per second) 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 3 seconds or downloading it in about 6 seconds. It also boasts random read and write IOPS (input output operations per second) of up to 190K and 150K respectively, to easily handle high-speed operations. A hard drive, by contrast, will only process up to 120 IOPS in random reads, making the new Samsung SSD more than 1500 times faster than an HDD in this regard.
The new PM971-NVMe SSD line-up will be available in 512GB, 256GB and 128GB storage options to OEMs starting this month worldwide.
