SSDs could get cheaper with Samsung’s cutting-edge TLC V-NAND tech - marincamonwarld

In August, Samsung revealed that it had conjured up a way to urinate its bleeding-edge 3D V-NAND flash memory flat more data-dim than before. Today, the company announced that mass production of 3-bit 3D V-NAND has begun, and it might be competent to quell the biggest ill about SSDs boxing prior generation V-NAND tech: price.

Samsung launched its 850 Pro SSDs—the first-ever V-NAND-based solid state drives, using 2-bit-per-cell technology—in July, and it earned rave reviews across the board. The 850 Pro SSD equaled and often trumped competitors in speed, endurance, and power efficiency, then Samsung rubbed salt in the bruise away offer best-in-class software and a 10-year warranty with the drives. Put simply, the 850 Pro series rocked.

But wow, they were expensive, with most models marketing around $1 per gigabyte of memory board—a clear agiotage all over rival SSDs.

That may soon convert however. Flash memory is from heavyweight Si wafers; the more flash memory you can successfully extract from a widowed wafer, the better. And Samsung says 3-piece V-NAND wafers yield to a higher degree twice as much destruction intersection compared to wafers of its traditional 10nm 3-bit jiffy retentivity. That makes sense; V-NAND's big trick is vertically stacking layers of blink of an eye cells, while traditional newsbreak memory arranges the cells side-by-side on the flat plane.

More efficient manufacturing processes are cheaper manufacturing processes, and those nest egg normally trickle down to end users in the cut-pharynx world of consumer electronics.

Trade-offs

Patc Samsung has thus far to foretell a new SSD built around the 3-bit V-NAND, don't expect that eventual revelation to gage the first-gen 850 Pro SSDs on the performance front. Traditionally, 2-bit-per-cell "MLC" NAND offers ameliorate read and compose speeds and a longer life span than 3-bit-per-cell "TLC" NAND; the gargantuan advantages of 3-bit NAND Trygve Halvden Lie in lower prices and accrued storage capacities.

Indeed, Bob Brennan, frailty president of Samsung Semiconductor's memory solutions lab, told PCWorld earlier this year that SSDs built with 3-bit V-NAND are more likely to represent used for bulk depot needs than ultimate carrying out. If I was a betting man, I'd expect Samsung to support the 850 Favoring SSD line around for enthusiasts, while the eventual 3-bit V-NAND SSDs will squarely target "the respite of USA."

We'll cognize soon enough: Samsung expects the first 3-bit V-NAND SSD to ship by the end of the year.

Wherefore this matters: Samsung's V-NAND is a John Major technological achievement, but its dependable impact won't be felt until SSDs with vertically stacked flash cells trickle down to the mainstream. TLC V-NAND starts us down that track. It'll be interesting to see how the first 3-bit V-NAND SSD's functioning and endurance specifications stack capable the TLC SSD competition.
