Samsung 860 EVO vs 860 QVO: Technical Comparison of SSDs

When buying an SSD , there are so many models on the market that it is often difficult to know which one is better and you end up looking only at the theoretical capacity and speeds. In this article we are going to make a technical comparison between the Samsung 860 EVO vs 860 QVO SSDs to see which of the two best-selling models of this manufacturer is better, and especially which one is more worth buying.

If we only stick to the cost, both SSDs have fairly even prices (although the QVO model is frequently on sale and is cheaper). For reference, these are the prices of the 1 TB variants of both models:

But let’s see what technical characteristics these two solid state devices offer to check if one is superior to the other, or on the contrary, neither stands out above the other and it is only worth looking at the price when buying them.

Technology Samsung V-NAND 3D NAND QLC
Warranty 5 years 3 years

It is obvious that in terms of theoretical performance we do not have a winner, because their speeds are exactly the same. Both SSDs use the Samsung MJX controller and have 1GB of DDR4LP SDRAM cache , so this is perfectly normal.

We did find differences in terms of the interfaces offered, since while the 860 QVO is only available in 2.5-inch format, the 860 EVO is also offered in M.2 and mSATA formats.

The main difference between both SSDs lies in the type of chips used; While the Samsung 860 EVO makes use of 3D NAND QLC chips, the 860 EVO uses Samsung V-NAND chips which are MLC chips . As a result, the Samsung 860 EVO has a much longer durability than the 860 QVO and, therefore, its warranty period is also much longer.

Additional characteristics

The Samsung 860 EVO boasts of TRIM support, 256-bit AES encryption support, SMART support, DevSleep and Garbage Collection support, and is supposed to have a durability of 1.5 million hours.

For its part, the Samsung 860 QLC slightly expands those features, since in addition to having TRIM, SMART, DevSleep and Garbage Collection support, it extends the encryption compatibility with AES-256, TCG / Opal and IEEE1667, in addition to adding support for WWN .

Otherwise, they are two identical SSDs in terms of their additional features, including of course compatibility with the Samsung Magician software.

Which of the two is worth buying?

As we have seen in this comparative technique of the Samsung 860 EVO vs 860 QVO SSDs, they are two very similar SSDs in terms of characteristics and performance, but the EVO model wins in terms of durability, and it also does so by a landslide.

In other words, unless there is a very good offer for the 860 QVO that makes the price difference substantial, the 860 EVO is a better SSD because, with equal performance, it has much better durability and will be a device that It will last at full capacity for much longer.
