Samsung Promises High-Performance Storage with new Fifth-generation V-NAND

Samsung Promises High-Performance Storage with new Fifth-generation V-NAND

Samsung announced it has begun mass producing its fifth-generation V-NAND memory chips with the fastest data transfers now available. In its first use of the ‘Toggle DDR 4.0’ interface, the speed for transmitting data between storage and memory over Samsung’s new 256-gigabit (Gb) V-NAND has reached 1.4 Gbps, a 40-percent increase from its 64-layer predecessor.

The energy efficiency of Samsung’s new V-NAND remains comparable to that of the 64-layer chip, primarily because the operating voltage has been reduced from 1.8 volts to 1.2 volts. The new V-NAND also has the fastest data write speed to date at 500-microseconds (μs), which represents about a 30-percent improvement over the write speed of the previous generation, while the response time to read-signals has been significantly reduced to 50μs.

Packed inside Samsung’s fifth-generation V-NAND are more than 90 layers of ‘3D charge trap flash (CTF) cells,’ the largest amount in the industry, stacked in a pyramid structure with microscopic channel holes vertically drilled throughout. These channel holes, which are only a few hundred-nanometers (nm)-wide, contain more than 85 billion CTF cells that can store three bits of data each. This state-of-the-art memory fabrication is the result of several breakthroughs that include advanced circuit designs and new process technologies.

Thanks to enhancements in the V-NAND’s atomic layer deposition process, manufacturing productivity has also increased by more than 30 percent. The cutting-edge technique allows the height of each cell layer to be reduced by 20 percent, prevents crosstalk between cells and increases the efficiency of the chip’s data processing.

“Samsung’s fifth-generation V-NAND products and solutions will deliver the most advanced NAND in the rapidly growing premium memory market,” said Kye Hyun Kyung, executive vice president of Flash Product and Technology at Samsung Electronics. “In addition to the leading-edge advances we are announcing today, we are preparing to introduce 1-terabit (Tb) and quad-level cell (QLC) offerings to our V-NAND lineup that will continue to drive momentum for next-generation NAND memory solutions throughout the global market.”

Samsung will be quickly ramping up production of its fifth-generation V-NAND to meet a wide range of market needs, as it continues to lead the high-density memory movement across critical sectors such as supercomputing, enterprise servers and the latest mobile applications such as premium smartphones.

Soooooooooooo what you're saying is..........? That I am going to wait for them SSD's to replace my mechanical ones until these things drop to reduce the cost on the old ones?!? Was just looking at the abysmal read and write speeds of my HDD's trying to maintain speeds/performance while reading from and being written to at the same time. Just sad TBH....

Costs to replace all mechanical, but one 3th drive would be just over $500 and that is replacing four 500gb Seagate that are 7200rpm.... Thinking of going with two 1tb Samsung Evo's..

Anyone gots that proverbial input for me on my approach??

Most ssds would give better performance, even if its a value/mainstream one.
Looked at the crucial mx500?

Either I don't understand where you're thinking mainstream SSDs would offer better performance, or you don't understand that what Samsung is doing here is the performance of a single chip, without the controller. Remember, a single chip doesn't really offer impressive specs. What makes an SSD so good is the controller, since it's basically a processor that figures out how to maximize the throughput of each chip available. I personally like to think of it as a specialized RAID0 controller (I understand it's a bit more complex than that). I figure this is also why lower-capacity SSDs have a tendency to perform worse than their higher-capacity equivalents, since they often have fewer chips to read/write to.

All that being said, if Samsung created a single chip that can (by itself) nearly match a the performance of value SSD (with a controller), they created something pretty fast.

if me, i will keep using hdd for non-critical things (performance related)
until SSD have similar capacity and price

current avg HDD storage (most people pick) is 4TB.... with max 10TB
SSD avg storage still 512GB~1TB, been catching up really well... and there is 10TB+ ssd if you willing to pay it with your organ

^I would argue the average for probably 90% of users is actually around 240 or 256gb but i agree use the hdd's for things like video/music and files u dont use often like old game's u dont play often.
