TeamGroup T-Force Cardea Z44Q 2TB, M.2 2280 / M-Key / PCIe 4.0 x4, Kühlkörper

As a piece of hardware, the Z44Q is a product we can recommend, but as stated the people will judge on endurance mostly, QLC has a bit of that scare factor. Realistically writing 50 GB per day every day each year would still make this 4TB SSD last almost 44 years, and that is true fact. That's 22 years for the 2TB model. I see QLC SSDs as a good option for laptops and cold storage, say NAS storage of your movie or game collection. If you want a bit more ease of mind then your next stop is a TLC-based SSD. However, there is another major influencing dynamic to consider in the NAND arena, ... pricing. QLC will need to come down in price significantly for it to make enough sense. Currently, you can find TLC-based SSDs in more or less the same performance class going for less than 15 cents per GB. Of course end-users will fee towards the TLC NAND product series for reasons aforementioned. Performance-wise this QLC product did not disappoint at all but at PCIe Gen 4.0 you'd expect a little more. The dreaded QLC write hole has been polished away by a huge buffer, so for normal and everyday usage and say a gaming PC, really it's an advised product multiple times faster than any of the fastest SATA3 SSDs. But pricing levels for QLC, as stated, need to come down before a larger audience will accept and adopt QLC based SSDs. The huge plus today is volume size, a 4 TB version of this SSD is incredibly nice to have, and that is the sole advantage of QLC. If you want it, this is a proper product offering good overall performance and really good IOPS, and sustained performance. However for QLC to get accepted, prices need to come down, at least substantially below TLC NAND prices.
