Solid State Storage continues to come down in cost and scale higher in speed and density. Though spinning hard disk media will likely have a place at least in the data center perhaps for generations to come, SSDs are making great strides, driving toward cost parity with HDDs with each new generation of product, while offering orders of magnitude performance gains and even higher reliability in many applications. One of the biggest names in Flash storage is Samsung, from their consumer grade SSD 950 Pro and 850 EVO lines to the squarely enterprise-targeted product the company has announced for volume...

The rapid pace of innovation in the solid state storage market shows no signs of letting up. In only a few generations, the industry bumped up against the limits of the legacy SATA interface, and began leveraging PCI Express for additional bandwidth with some passable, though somewhat clunky bridged solutions (in retrospect). Then some ultra-fast, native PCI Express offerings hit, and have since evolved into multiple form factors, including slotted and gumstick models, with varying physical interfaces.Some of the more recent introductions, like the excellent Intel SSD 750, feature many of the latest...

NAND flash technology is advancing at a rapid clip, and that’s resulting in solid state drives (SSDs) that are faster, more capacious and cheaper (per GB). Look no further than Samsung’s announcement this week of its latest Vertical NAND (V-NAND) chips that allows for the ultra fast PM1725 NVMe SSD capable of delivering mind-blowing sequential read speeds of up to 5,500 megabytes per second. But if you think those read speeds are impressive, Samsung just made our jaws drop with the announcement of an incredible advancement on the storage density front. The company’s new PM1633a SSD manages to pack... Read more...
Sometimes it's the enterprise sector that gets dibs on the coolest technology, and so it goes with a trio of TCO-optimized, high-performance solid state drives from Samsung, all three of which are based on three-dimensional (3D) Vertical NAND (V-NAND) flash memory technology. And get this -- the fastest of bunch can read data at up to 5,500 megabytes per second. That's the rated sequential read speed of Samsung's PM1725, a half-height, half-length (HHHL) card-type NVMe SSD. Other rated specs include a random read speed of up to 1,000,000 IOPS, random write performance of up to 120,000 IOPS, and... Read more...
Samsung announced that it is putting its second generation of Vertical NAND (V-NAND) flash memory into mass production, and unlike the enterprise-facing first-gen V-NAND products, this new glut of storage is aimed at high-end consumer storage. This generation features 32-layer 3D V-NAND, which is a step up from the older generation’s 24 layers, although Samsung says that it can use essentially all the same manufacturing equipment, which saves a bundle on cost. This isn’t just theoretical stuff, though; Samsung is releasing a lineup of consumer SSDs with the technology in capacities... Read more...
Sadly, we're still waiting for SSDs to completely replace HDDs in the mainstream, but Samsung's unleashing a new solid state drive into the enterprise that'll have even average consumers drooling. The company has launched what it says is the world's first 3D V-NAND based SSD for enterprise applications. Samsung's V-NAND SSD comes in 960GB and 480GB versions, with the larger boasting the highest level of performance, offering more than 20 percent increase in sequential and random write speeds by utilizing 64 dies of MLC 3D V-NAND flash, each offering 128 gigabits (Gb) of storage, with a six-gigabit-per-second...

Samsung announced that it has developed and begun mass producing a new kind of NAND flash that could shake up the storage industry by substantially increasing the reliability, scaling, and performance of flash. The product is three dimensional vertical NAND (or 3D V-NAND), and it’s slated for use in both the consumer and enterprise markets in embedded storage and SSDs. By using a vertical cell design with 3D Charge Trap Flash (CTF) technology and a “vertical interconnect process technology” that links the cell array, Samsung enabled a single-chip density of 128Gb. In a release,... Read more...
