Samsung recently announced that they would be releasing QLC NAND based SSDs. TLC writes three bits per cell, QLC writes 4-bits per cell. New products named Samsung 860 QVO are surfacing everywhere right now at etailers in volume sizes of 1TB, 2TB, and 4 TB. And the prices look to be very sweet.
French online store NASexpert, for example, is listing three models, with sizes of Samsung 860 1, 2 and 4 TB QVO (Quality & Value Optimized SSD). The 1 Terabyte SATA-SSD would cost 118 euros, the 2 TB SSD would sell at 226 euros and the 4 TB variant is only 452 euros.
Endurance could be a thing with the new QLC drives, albeit we doubt it. Computerbase writes that the new SSDs can deal with up to 1,440 Terabytes, that most likely is the 4 TB model, so if you half that by size that is 720 TBW for the 2TB model and 360 TBW for the 1 TB model. In pale comparison, the Samsung 860 Evo (4 TB model) has an endurance of 2,400 terabytes written. Overall, the TBW values seem to be half that of the EV. Another difference is the warranty. The 860 Evo has a 5-year warranty, while the 860 QVO has a 3-year warranty. They also mention that random reads are listed at 96,000 IOPS, and random writes ay 89,000 IOPS. The maximum read speed would be 550 MB/second, and the maximum write speed would be 520 MB/s. NASexpert reports that the SSDs will probably be available in December.
Of course, you will read all the juicy details once we post our review.
