Samsung likely sees less value in dedicating engineering and production capacity to optimizing new high?density NAND for the 600MB/s ceiling of SATA, especially when NVMe can use the same NAND at much higher speeds. If Samsung eventually scales back SATA SSDs, the market may rely more on smaller brands and lower?tier OEMs, which can make it harder to find high?quality, long?warranty SATA drives at consumer?friendly prices. That doesn’t mean Samsung?grade reliability is gone, but the easiest path to it through Samsung’s 800?series may narrow.

To begin with, SATA drives are easy to cool. Their plastic/metal 2.5-inch shells act as natural heat sinks, meaning you don't have to implement active cooling. However, NVMe drives aren't so easy to deal with. As you migrate to high-capacity M.2 drives to replace your SATA storage, you might encounter thermal throttling. High-capacity NVMe drives, particularly faster, more modern drives, run extremely hot and, as a result, can slow themselves down to prevent overheating and damaging their internal components.

In order for you to prevent this further, you also need to make sure you have active cooling in place or at least a heat sink, which doesn't come included with the drive itself. This is another cost you have to incur on top of the price of the drive itself being more expensive than SATA to begin with.
