Samsung recently announced that they would launch their SSDs with QLC NAND, the latest type of NAND that has come out of the labs and that aims to lower the price of SSDs even more, at the expense of the durability of these units. to remember, the higher the density of data inside a NAND chip, the lower the durability of the chip.
Anyway, NASexpert has three models of SSD Samsung 860 QVO units, in sizes of 1TB, 2TB and 4TB. Their prices are especially striking, with a price of 118 euros for the 1TB model, 226 euros for the 2TB model and 452 euros for the 4TB model, without a doubt, especially striking prices for SSD units with capacities that exceed TB capacity.

In terms of performance, the new SATA 4TB SSDs with QLC V-NAND memory (4-bits per cell) will deliver similar performance to SSDs that use V-NAND TLC memory (3-bits per cell).
However, because increasing the capacity per chip produces a drop of up to 50% in the electrical load necessary to determine which cells have information, the alternative that Samsung will use is to use a 3-bit controller in conjunction with its TurboWrite Technology to maintain the same levels of performance.
In this way we have that 4TB SATA SSDs with NAND QLC will be conformed with up to 32 fourth-generation and 64-layer V-NAND memory chips, and will be able to deliver a sequential read / write performance of 540 MB / s and 520 MB / s, respectively.
