Samsung Announces SSD 850 EVO Series Featuring 3-bit V-NAND

Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today launched the 850 EVO, the latest addition to its branded solid state drive (SSD) line-up. Based on Samsung's 3-bit 3D Vertical NAND (V-NAND) technology, the 850 EVO SSD provides a significant boost in performance and endurance as compared to its predecessor, making it ideal for use in mainstream PCs. With the slogan of "a new caliber of performance & endurance," the new drive will be globally launched in a total of 53 countries in the United States, Europe and Asian markets later this month.

"We are thrilled to be providing users with an improved computing experience through the new 850 EVO SSDs," said Unsoo Kim, Senior Vice President of the Branded Product Marketing team at Samsung Electronics. "Samsung will continue to introduce V-NAND-based SSDs in a variety of form factors, while accelerating the growth of the global SSD market."
While the Samsung 850 PRO SSD that launched in July uses 2-bit 3D V-NAND for professional use in high-end client PCs and small- and medium-sized enterprise servers, the 850 EVO is built with 3-bit 3D V-NAND technology. This makes it more suitable for general consumer use in devices such as notebook and gaming PCs. With the introduction of the 850 EVO, Samsung launches the next iteration of its consumer SSD product line-up with new V-NAND-based SSDs.

The Samsung 850 EVO series comes in 1TB, 500GB, 250GB and 120GB capacity options, and boasts sequential read speeds of up to 540 megabytes per second (MB/s) and write speeds of up to 520 MB/s. With Samsung's TurboWrite technology, the 1TB version of the 850 EVO offers random write speeds of up to 90K IOPS, which enables fast storage of high volume data and multi-tasking operations. Additionally, the drive features outstanding reliability with 80GB data writes per day for five years in the 500GB and 1TB models.

Next year, Samsung plans to introduce an extended line-up of the 850 EVO in mSATA and M.2 form factors, based on 3-bit V-NAND technology. Samsung also expects that the 850 EVO will drive the expansion of the high-density SSD market, while satisfying the increasing market need for SSDs over 500GB in storage capacity.

I ain't convinced 3-bit is as reliable as claimed. Time will tell. This is primarily a cost saving design.

3bit/TLC 2d nand on the 840Evo made it through 900TB of writes on the 250GB drive...
The 840 pro 2-bit MLC has just breached 2PB and is still going.

Yes it is common knowledge that TLC is not going to last as long as MLC.
It however is good enough for many years of writes for the common person.

Something the 850evo does is set aside SLC cache (single level cells) aside for caching.
There is always a better enduring drive...

Enterprise drives are rated in writes per day... some up to 30/day for a 5 year life.

I would not be worried about these new TLC drives dying before you want to replace them for something faster.

Pretty much anything except the first couple rounds of SSDs are going to be indistinguishable for the average casual user, ignoring the few lemon drives where they switched in really bad flash after the reviews were published, and that one oddball Crucial drive that had a USB controller. And the SandForce drives that kill themselves. Or the Samsung TLCs that slow down with time. Hmm, the list is pretty long actually ...

on a different note, tigerdirect is offering the 840 evo 250GB with Farcry 4 for 100 bucks if you checkout with visa checkout. is it worth it going from a regular 840 to the 840evo?

If you do, don't forget to apply the firmware fix for the 840 EVO that I just mentioned in the previous post, unless you like 20MB/s after 4 weeks.

I suspect TLC V-NAND will have no worse durability than the 2-bit MLC of yesteryear.

The Intel VNAND will make for some interesting competition.
