Samsung's new flash stands above the competition

As you saw in Al's review, the Samsung 850 drive is more than just a small bump in model number and performance, it is the stellar introduction to 3D NAND.  The Tech Report is likely having nightmares from the drives reported longevity which is expected to be up to 10 times the cycles of current drives and means an update to their long running endurance test could see them testing into the 2020's.  While they haven't yet added the 850 to that particular test they did post a review which starts out with a comprehensive look at the history of Flash technology and why 3D NAND is faster and more resilient than previous types; read on to get  a better understanding of the fastest consumer SATA drive on the market.

"Most flash memory is limited to a single layer, but the V-NAND chips in Samsung's new 850 Pro SSD stack 32 layers on top of each other. This is next-level stuff, literally, and it's supposed to make the 850 Pro the fastest SATA drive around. We investigate."

Here are some goodies from yesterdays briefings at the 2014 Samsung SSD Summit:

Slides from the 3D V-NAND discussion. These provide some additional visuals for what I explained in the intro to the 850 PRO series SSD review:

Next we got into current launching lineups. First the 850 PRO that launched today:

Samsung also launched an 845DC PRO, which uses the previous generation 24-layer V-NAND:

Finally, as we walked out of the conference, we saw a 32-layer V-NAND wafer on display:

Introduction

Samsung has certainly been pushing the envelope in the SSD field. For the past two years straight, they have launched class leading storage products, frequently showing outside-the-box thinking. Their 840 PRO series was an impressive MLC performer to say the least, but even more impressive was the 840 EVO, which combined cost-efficient TLC flash with a super-fast SLC cache. The generous SLC area, present on each die and distributed amongst all flash chips within the drive, enabled the EVO to maintain PRO-level performance for the majority of typical consumer (and even power user) usage scenarios. The main win for the EVO was the fact that it could be produced at a much lower cost, and since its release, we've seen the EVO spearheading the push to lower cost SSDs.

All of these innovations might make you wonder what could possibly be next. Today I have that answer:

If you're going "Hey, they just changed the label from 840 to 850!", well, think again. This SSD might have the same MEX controller as its predecessor, but Samsung has done some significant overhauling of the flash memory itself. Allow me to demonstrate.

Here's standard (2D) flash memory, where the charge is stored on a horizontal plane:

..and now for 3D:

The charges (bits) are not stored at the top layer. They are stored within all of those smaller, thinner layers below it. You're still looking at a 2D plane (your display), so here's a better view:
