WD recently updated its mainstream Blue line of solid state drives with new 64-layer 3D BiCS NAND flash memory. When we first took a look at the original WD Blue SSD, we found it to be an admirable performer with competitive pricing. This new generation of drives, however, promises better performance and features all of the firmware tweaks and optimizations WD has gleaned over the Blue SSD line’s lifetime.In addition, SanDisk branded versions of the drive are hitting the market as well. Internally the WD Blue with 3D NAND and new SanDisk Ultra 3D are virtually identical, but the drives will target...

Memory chip maker Hynix continues to make impressive (and fast) strides in the field of NAND flash memory. Having launched 36-layer 128-gigabit (Gb) three-dimensional (3D) NAND flash chips in April 2016 followed by mass production of 48-layer 256Gb 3D NAND chips just seven months later, the company is now touting the industry's first 72-layer 256Gb 3D NAND flash chips. Hynix is using its own technologies to build these new NAND flash chips, which are based on triple-level cell (TLC) memory. TLC NAND chips are typically found in budget oriented solid state drives (SSDs) as they're less expensive...

Intel has been relatively quiet on the solid state drive (SSD) front lately, though the company has likely been devoting a lot time and resources to its upcoming 3D XPoint storage architecture. However today, the company has unleashed a flood of new SSD products that cover a broad spectrum of usage scenarios. All of the new SSD products make use of 3D NAND, while the cheapest of them can be had for less than $100. First up is the SSD 600p Series, which is offered in four capacities ranging from 128GB on up to 1TB, and is targeted at consumer desktops and notebooks. The SSDs are available in the...

Western Digital, a major player in the storage industry, announced this week that it has completed development of its next generation 3D NAND technology called BiCS3. Limited production is already underway in Japan with initial output expected later this year. If everything goes to plan, volume production will begin in the first half of next year. BiCS3 is the third generation of Bit-Cost Scalable NAND jointly developed between Western Digital and Toshiba. It's the world's first 64-layer 3D NAND solution, delivering the smallest chip area of any published 3D NAND. The initial plans are to deploy...

At some point in time, solid state drives (SSDs) are likely to finally supplant mechanical hard disk drives (HDDs) just as USB thumb sticks replaced floppies, but it won't happen until the cost of NAND flash memory drops even further, paving the way for parity in terms of price-per-gigabyte. It may even happen sooner than later—BeSang Inc., inventor of 3D monolithic chip technology in 2010, claims to have found a way to reduce the cost of 3D NAND from over 20 cents per gigabyte to just around 2 cents per gigabyte. The path to cheaper 3D NAND lies in shrinking the cell size of the overall structure,...

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...
