Samsung 850 evo vs samsung 860 evo which is better?

Samsung 860 EVO is the renewal of one of the best SSDs that we can find on the market, and clearly the best if we talk about 2.5-inch models with the SATA III 6 GB / s interface. These types of SSDs have evolved little in recent years, although Samsung always finds some way to improve what it offers its users. We see all the improvements that have been introduced in Samsung 850 EVO vs Samsung 860 EVO.

Samsung 850 EVO vs Samsung 860 EVO: improving what was excellent

Samsung 850 EVO and Samsung 860 EVO have very similar sales prices and characteristics that do not seem too different, although we are going to check if there are any major changes inside. Both models are based on Samsung's 64-layer V-NAND memory technology, although with the difference that the 850 EVO uses TLC-type memories, and the 860 EVO uses 3-bit MLC-type memories.

	Samsung 860 EVO	Samsung 850 EVO

Controller	Samsung MJX	Samsung MJX
Memories	V-NAND MLC 64 layers (really is a TLC)	V-NAND TLC 64 layers
Sequential reading	550 Mb / s	540 Mb / s

4K writing	90, 000 IOPS	88, 000 IOPS

Greater resistance and slightly higher speed

MLC memories offer lower storage density as they only store two bits per cell, compared to 3 bits per cell in TLC memory. This makes TLC memory offer 50% more storage density, helping to reduce the size of the chips used to manufacture the SSD, and therefore its price. However, not everything is pink with TLC memory, since storing more bits per cell makes it wear out faster, this means that MLC memories are more durable. But Samsung uses it for marketing, since its 3-bit memories are equivalent to TLC memories.

Therefore, we already have an important difference, the Samsung 860 EVO will last us longer than its predecessor making the same use of both. The Samsung 860 EVO 4TB is capable of supporting up to 2400TB of written data, while the 850 EVO of the same capacity only supports 1200TB written.

Endurance (TB)
	Samsung 860 EVO	Samsung 850 EVO
250 GB	150	75
512 GB	300	150
1TB	600	300
2 TB	1200	600
4TB	2400	1200

In terms of performance, Samsung promises up to 550 MB / s of sequential write and up to 520 MB / s of sequential read on the 860 EVO, and 540 MB / s and 520 MB / s respectively on the Samsung 850 EVO. The improvement is negligible in this regard, as are the random read and write speeds left at 98, 000 IOPS on the 860 EVO and 90, 000 IOPS on the 850 EVO. Our tests confirm that there are hardly any differences, since we have obtained almost the same results in the different benchmark applications used. The Samsung 860 EVO is somewhat faster overall, but the difference is pretty slim.

Final words and conclusion about Samsung 850 EVO vs Samsung 860 EVO

The conclusion is clear, Samsung has maintained the benefits, but has changed the V-NAND TLC memories for the V-NAND ML C, which allows to slightly improve the durability of the new Samsung 860 EVO making you much more attractive than its predecessors., especially if we consider that the price is the same or almost the same.

If you have a Samsung 850 EVO, you are not worth taking the leap , unless you are thinking of getting a larger capacity model. On the other hand, if you are going to buy a new SSD, it does not make much sense for you to go for the Samsung 850 EVO, because its successor offers you much more resistance and slightly higher speed. Samsung 860 Evo 1 TB is for sale for approximately 200 euros.
