Samsung have jumped up the alphabet, going from EVO to QVO with their new lower cost QLC based SSD family. The 4TB model Allyn reviewed sells for $600, not bad for a drive of that size but still a little pricey for some. A more affordable option can be seen at The Tech Report, the 1TB drive they reviewed sells for $150. If you are on a somewhat limited budget and don't mind a small hit in performance nor a three year warranty or 360TB written endurance then this drive is worth a look.
Samsung's EVO drives have ruled the SATA roost for the last several years. Today, Samsung is introducing high-capacity, lower-cost 860 QVO drives with four-bit-per-cell QLC NAND inside. Can they live up to the high expectations Samsung has set with its past products?"
Here are some more Storage reviews from around the web:

Samsung has opted to name this new product 'QVO'. The Q presumably stems from the use QLC flash, which can store four bits per cell.
While QLC writes are far slower than what we are used to seeing from a modern SSD, SLC caching is the answer to bridging that performance gap. The 860 QVO employs Samsung's Intelligent TurboWrite, which has a minimum 6GB static cache plus a dynamic cache of up to 72GB. This dynamic cache varies based on available QLC area which can be reconfigured to operate in SLC mode. Do note the 'After TubroWrite' speeds of 80 and 160 MB/s - that's the raw QLC speeds that you will see if the cache has been exhausted during an extended write period.
The rest of the specs are about what we expect from a SATA SSD, but I do have a concern with those QD1 4KB random read ratings of only 7,500 IOPS. This is on the low side especially for Samsung, who typically dominate in low QD random read performance.
