Samsung has just announced 2TB 850 PRO and 850 EVO SSDs today. The drives aren't showing up on the company website yet so there is no pricing info yet but, according to the press release, the 2TB 850 PRO for 10 years or 300 terabytes written, and the 2TB 850 EVO for five years or 150 TBW.

Samsung, a market leader in advanced memory technology and an innovator in consumer electronics, today introduced the 2-terabyte (TB) 850 PRO and 850 EVO solid state drives (SSDs). Samsung’s 3D Vertical NAND (V-NAND) based retail SSD lineup now features 20 different products with a wide range of capacity options from 120 gigabyte (GB) to 2TB. Available in 50 countries, the launch of the 2TB drives addresses the ever-increasing consumer demand for high-performance and high-capacity memory solutions.

The new 2TB 850 SSD PRO and EVO drives remain in the same 7-millimeter, 2.5-inch aluminum case as their predecessors did. Equipped with Samsung’s advanced chip solutions, including 128 individual Samsung 32-layer 128Gb 3D V-NAND flash chips, an upgraded high-performance MHX controller that supports 2TB capacity, and four 20nm-class process technology-based 4Gb LPDDR3 DRAM chips, the 2TB 850 family provides industry-leading performance and power efficiency. With added capacity, professionals and consumers can experience a smoother computing environment prepared for the intense demands of rich content such as 4K UHD video editing and viewing.

If these are reasonably priced I'm getting one. I've been wanting a size and performance upgrade to my SSD.
 
TLC? more hardware defects like the 840's? NOPE NOPE NOPE OCTOPUS
 
TLC potentially has lower endurance, but realistically speaking, still at least an order of magnitude above what most consumers will be writing to these drives. The bigger issue with Samsung drives has been the performance drop over time due to some bugs in the firmware. I don't think that has been completely resolved yet.
 
Don't see the price mentioned anywhere but there are other sites saying it will be $800/$1000 for the evo/pro version. I think we are still a couple of years away from ssd's replacing HD's for bulk storage. They are great for fast main drive access but there is no way I'm replacing all the spinning disks in my file server until they are $100/tb or less.
 
Fun Part of the article:

The overall lifespan of the ICs has been reduced from 10,000 towards 5,000 program/erase cycles. Rumors are, that the numbers for consumer grade 20/25nm NAND flash memory (as used on the SSD tested today) are even lower at 3,000 program/erase cycles. But granted, as drastic as that sounds, it's all relative as this lifespan will very likely last longer than any mechanical HDD. Drive wearing protection and careful usage will help you out greatly. With an SSD filled normally and very heavy writing/usage of say 10 GBs data each day 365 days a year, you'd be looking at roughly 22 full SSD write cycles per year, out of the 3,000 (worst case scenario) available.

Much as I love Guru3D, when they leave the price till the END of the review it makes me upset.

Feel like I'm listening to a used car salesman.
 
That said, I'm still waiting on the SSD makers to move to PCIE 3.0 for the M.2 slot. So far there is ONLY Samsung selling SSD's in that bracket and they're insanely fast
 
Is it me or have I never had a problem with a SSD?

I even have a 4+ year Vertex 3 that's used in my rendering machine taking a daily pounding without issue.

And the Samsung 840 Pro's have been rated the most durable SSD's ever made. So am I missing something here?

The 840s have an issue where they slow way down over time. There's been a couple firmware releases to fix it but I hear some are still having issues.

I'm still rocking an Agility 2 as a game drive and no issues so far.

Knock on wood but I've never had a major issue with the 3 Samsung drives I have - 256GB 840 Pro, and 2x512 GB 840 Evos. The Evos did have the speed issue but the firmware update seemed to fix it for me.

The article you linked to mentions the drives were run in a RAID configuration and in Linux, perhaps the corruption issue doesn't exist in Windows on a non-RAID setup.

My 840 Pro has been heavily used too... 40 TB written so far
 
The 840 EVO had that performance degradation issue due its use of smaller-node TLC. I'm unaware of any such issue with the MLC 840 pro.

I'm hoping the newer implementation of TLC (which really uses a physically larger manufacturing process, and V-nand) in the 850 EVO will provide stable performance long-term. They probably have more headroom for the 8 voltage states required to represent 3-bits (TLC = 3-bit = 2^3 = 8 discrete voltage states). I haven't studied the issue in any real depth, but from my vague recollection:
I assume there are ranged thresholds for each voltage state, and in-between states an advanced error-correction algorithm... and then that the 19nm or 20nm process or whatever that was used in the 840 evo make it physically difficult to maintain proper voltage calibration over time, resulting in dependence upon that correction algorithm, and ultimately performance degradation. And I guess that is why a re-calibrating firmware was required, and will probably work to varying degree...and duration... OR I'm just mis-informed... heh

With regard to that and other firmware issues: I'm...slightly worried about my 850 pro, and slightly more worried about my dad's 850 evo.

I kinda wish I had jumped on that Sandisk 480gb extreme pro when it was down near $205 a long while back. BUT - I think it'll be ok.
 
I have 2 x 1TB EVO SSDs and neither have given me any issues. I'd be all over the 2TB EVO depending upon the price.
 
This should further push down pricing. The 500GB version was over $200 not long ago, it's now down to $161 and might drop further.

Course with the size of games these days 500GB might not even suffice anymore.

Except your "warning" makes as much sense as complaining about Ford Pintos when the car in question is a Ford Focus from 2015.

The 840s definitely had problems, but the 850s are based on an entirely different technology.

Apples and oranges. Stop fear-mongering.
 
My 160GB Intel's in RAID0 are getting a little long in the tooth...

Replace with a single 2TB? Yes, please! Then I wouldn't have to download steam games multiple times and juggle to make space.

Did you guys read his link or just assume it was the 840 Evo performance degradation? The current issue being discussed includes the 850 Pro.

You shouldn't use any Samsung SSD on a Linux system at this point.
 
That price premium isn't all that bad. Now lets see what Amazon and the Egg list them for :D
 
Need 4TB Pros for $250/ea. That would be something to get excited about.
 
When you're paying $.50/GB for smaller capacities, paying the same for a 2TB doesn't seem worth it...

Hope it's the start of price drops across the board for all capacities though.
 
Why are the news articles so excited about the 850 PRO warranty for 2TB when the warranty is identical to that of 512GB/1TB? It's not like it's anything new. Am I missing something?
 
It's still completely nuts to see a 10 year warranty on any electronic device, much less SSDs which everyone still thinks are more perishable than HDDs.

Because they were excited before about the 10 year warranty and are still excited about it.

I'm excited about it but I'm also shocked the Evo (a cheaper alternative) carries an impressive 5 year. These are warranties you see on enterprise grade equipment!
 
Now I get it!

I still think I want to wait for an 860 PRO series or equivalent though I know it could be a while.
 
I'm in need of a storage system upgrade and my needs require up to hundreds of TB.
I was thinking of getting a 60 bay Storinator from 45drives, but now I'm questioning whether or not in 4-5 years, 4-8TB SSDs are going to cost the same as enterprise drives today, considering HDDs aren't going to grow anytime soon because of all the density and technology issues.

Kind of makes it hard to decide if I want to invest in a 60 bay system if in 3-5 years, I could be filling it up with SSDs that consume 1/10th of the power and require half the space. I'd then say that the enclosure is not suited for SSD because of SSD format and would be wasted and the $1K power supply would be unneeded if 4/6th of the drives are SSDs which don't consume power. FYI, I'd be buying disks as storage needs grow, power costs money and why spin unused HDDs and wear them out unnecessarily.

Hard to pick a long term storage solution at this point.

Wish Samsung would hurry up and release 4TB already at $500 price point, then I'd buy those SSDs instead of 4-6TB WDs enterprise and get Storinator enclosure modified for SSDs instead of 3.5" format.

Back in 2010 I saw companies at LinuxWorld Expo demoing 3.5" SSD for enterprise drives with like 2TB of space, I wonder if Samsung at all plans to release 3.5" format SSDs. With current technology, those puppies would probably contain up to 20TB.

Drool...not that I could afford one, but it would be awesome.

I'd be happy with a 4TB SSD at a reasonable price point.
