Samsung 860 EVO SSD Makes an Appearance

Hot on the heels of Samsung updating its website with its next performance-segment SSD 860 Pro series, with its range-topping 4 TB variant, a similar pre-launch website update revealed the company's next mainstream SATA SSD, the 860 EVO. The drive will be available in three form-factors, 7 mm-thick 2.5-inch, M.2-2280, and mSATA; all with SATA 6 Gbps interface. The 2.5-inch version comes in 250 GB, 500 GB, 1 TB, 2 TB, and 4 TB variants; while the M.2-2280 version comes in just 500 GB, 1 TB, and 2 TB variants; and the mSATA version in 250 GB, 500 GB, and 1 TB variants. The drives combine Samsung's latest generation 3D VNAND flash memory built in the 10 nm-class sliicon fabrication process, with an updated controller and refined firmware.

The 860 EVO offers sequential transfer rates of up to 550 MB/s, with up to 520 MB/s sequential writes, up to 97,000 IOPS 4K random reads, and up to 88,000 IOPS 4K random writes. The new-generation flash is rated for "8 times higher" endurance than the 850 EVO series; with up to 2,400 TBW. Samsung is reinforcing its faith in the drive by backing it with 5-year warranties. The company is introducing the new TurboWrite feature, which is a user-configurable SLC cache. You can set anywhere between 12 GB to 72 GB of the NAND flash to function as SLC, so the controller can juggle hot data in and out of it, for improved performance, using the Samsung Magician software.

Basically Samsung bringing components uptodate in order to keep cost low.

I'm curious how they improved endurance that much.

Well, I know that pretty much all 850 Pro (the big ones) can do 1PB of writes without much hassle. They just used the values very conservatively before. And with some tweaks to NAND, they now feel confident to state such endurance.

How soon and How Much?

I see the Crucial MX500 1TB, on Amazon, has 3DNAND and a 5 year warranty. $259.99
Also, the 500GB, more my needs, is $134.99 with the same 5 year warranty...
Sequential reads/writes up to 560/510 MB/s and random reads/writes up to 95k/90k on all file types

I don't know much, but, M.2 with SATA3 read and write speeds? Didn't know that was possible.

You're making the same mistake anyone that doesn't read makes.
It's an M.2 drive, but it doesn't "speak" NVMe, it only "speaks" AHCI. Thus, it's very much a SATA drive.
M.2 can do that: https://en.wikipedia.org/wiki/M.2

I am still hanging on to an old Samsung 840 Evo 500 GB and i have been waiting in what seems like forever for the 860 Evo to show up
Hope that the 860 Evo 1 TB in the same price range as the new Crucial MX500 1 TB

Would be great. Sadly that mSATA one is likely going to stay high. Not much competition in that area.

The 850 Pro uses MLC NAND though these ones here use TLC NAND. The question is how did they improve their TLC NAND so much that it has 8x better endurance.

That's what I was wondering about, too. But we'll need anadtech's review to figure that out.

I was hoping for a 2tb msata drive to be released. I had heard that one of Samsung's portable drives does use a 2tb msata ssd, but the last time I checked it was priced at over $600. That was at least a year ago. Why no consumer release of a separate, individual 2tb msata ssd, not enclosed in a case, just by itself?

Could it have anything to do with mSATA going the way of the dodo?

And here I was under the impression that the 850 Pro was SLC. Where did I get that idea?

How would configuring the SLC cache impact capacity? Each cell I configure to work as SLC will cause me to lose the other 2bits. So configuring a 72GB SLC pool would make it "lose" an additional 144GB from the regular TLC pool? If the first 12GB already preconfigured as SLC then increasing to 72GB would drop the total drive capacity by 120GB?

I can accept that msata drives are not as popular as they were a few years ago, due to the fact that there are newer form factors and technologies like M.2 and NVME; the fact that Samsung are releasing these NEW and CURRENT drives in the msata form factor in addition to the other form factors, would suggest, that possibly, MAYBE, the form factor isn't quite as dead as some would believe. What I am saying is, if you are Samsung and you are acknowledging that there is at least SOME demand for msata, why not go just a little further and acknowledge that there might be demand, as well, for 2tb in an msata form factor?

Am I making too much of a leap in thinking that there are some current owners of 1tb msata drives that might perhaps wish for a 2tb msata drive? Am I crazy for thinking that???

2012, Samsung created 3D NAND - V1 – 850 PRO. – This was the first V-NAND SSD using 32 Layer SLC
2014 – Dec, Samsung ships 3D NAND V2. – 850 EVO using 32 Layer MLC
2016 – MarchSamsung transitions to 48-layer – 850 PRO using MLC and 850 EVO using TLC

I am having trouble finding where it says these are TLC. Where did you get that info?
