Model overview based on user reviews  
The A-Data XPG SPECTRIX S40G RGB SSD offers a visually appealing design with its beautiful RGB lighting. However, users have noted some performance issues, particularly with heat management. The SSD tends to heat up to 85 degrees, which significantly reduces the read/write speeds. The included radiator is described as a primitive aluminium plate and is not very efficient. In terms of capacity, the product offers a good capacity/price ratio, but the use of QLC memory in the 4TB version leads to a drastic speed drop to 150 Mb/s after the buffer is full. Overall, while the model is functional, it is considered nothing special and comparable to other models like the 8100, but with added backlighting.

NVME 1.3 needs cooling with liquid cooling

I bought the Spectrix S40G RGB 512GB at Сomputeruniverse
The lighting is beautiful
It heats up to 85 degrees, the radiator is a primitive aluminium plate. When heated, the stated read/write speeds are reduced by 2 times.

normal model, nothing special
3 May 2022 
Essentially the same 8100 only with backlight. In 4 TB version 4 memory chips marked ADATA, obviously at the moment there is no 1 TB per TLC chip. For example, the Corsair MP510 has 8 chips for a 4 TB drive. TLC is declared there, everything is fair. And here 3D nand is declared on the off site, and that's it .. :)
Capacity/price. There is a buffer at which the declared speeds are achieved
QLC memory (at least in 4 TB version). After buffer overflow, the speed drops to 150 Mb/s. The radiator is not efficient and sham
BlueBear: use A-Data AS40G-4TT-C few months
